7 Detailed Description
7.1 Description
This device contains six independent buffers with Schmitt-trigger inputs. Each gate performs the Boolean
function Y = A in positive logic.
7.2 Functional Block Diagram

One of Six Channels

xA xY

7.3 Feature Description

7.3.1 Balanced CMOS Push-Pull Outputs
This device includes balanced CMOS push-pull outputs. The term balanced indicates that the device can sink
and source similar currents. The drive capability of this device may create fast edges into light loads, so routing
and load conditions should be considered to prevent ringing. Additionally, the outputs of this device are capable
of driving larger currents than the device can sustain without being damaged. It is important to limit the output
power of the device to avoid damage due to overcurrent. The electrical and thermal limits defined in the Absolute
Maximum Ratings must be followed at all times.
Unused push-pull CMOS outputs must be left disconnected.
7.3.2 TTL-Compatible Schmitt-Trigger CMOS Inputs
This device includes TTL-compatible CMOS inputs with Schmitt-trigger architecture. These inputs are
specifically designed to interface with TTL logic devices by having reduced input voltage thresholds.
TTL-compatible Schmitt-trigger CMOS inputs are high impedance and are typically modeled as a resistor in
parallel with the input capacitance given in the Electrical Characteristics. The worst case resistance is calculated
with the maximum input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage
current, given in the Electrical Characteristics, using Ohm's law (R = V ÷ I).
The Schmitt-trigger input architecture provides hysteresis as defined by ΔVT in the Electrical Characteristics
table, which makes this device extremely tolerant to slow or noisy inputs. While the inputs can be driven much
slower than standard CMOS inputs, it is still recommended to properly terminate unused inputs. Driving the
inputs with slow transitioning signals will increase dynamic current consumption of the device. For additional
information regarding Schmitt-trigger inputs, please see Understanding Schmitt Triggers.
Do not leave TTL-compatible CMOS inputs floating at any time during operation. Unused inputs must be
terminated at VCC or GND. If a system will not be actively driving an input at all times, a pull-up or pull-down
resistor can be added to provide a valid input voltage during these times. The resistor value will depend on
multiple factors, however a 10kΩ resistor is recommended and will typically meet all requirements.

8 Application and Implementation

Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.

8.1 Application Information

The SN74ACT17 can be used to drive signals over relatively long traces or transmission lines. A series damping
resistor placed in series with the transmitter’s output can be used to reduce ringing caused by impedance
mismatches between the driver, transmission line, and receiver. The figure in the Application Curve section
shows the received signal with three separate resistor values. Just a small amount of resistance can make a
significant impact on signal integrity in this type of application.

8.2.1 Design Requirements

8.2.1.1 Power Considerations
Ensure the desired supply voltage is within the range specified in the Recommended Operating Conditions.
The supply voltage sets the device's electrical characteristics of the device as described in the Electrical
Characteristics section.
The positive voltage supply must be capable of sourcing current equal to the total current to be sourced by all
outputs of the SN74ACT17 plus the maximum static supply current, ICC, listed in the Electrical Characteristics,
and any transient current required for switching. The logic device can only source as much current that is
provided by the positive supply source. Ensure the maximum total current through VCC listed in the Absolute
Maximum Ratings is not exceeded.
The ground must be capable of sinking current equal to the total current to be sunk by all outputs of the
SN74ACT17 plus the maximum supply current, ICC, listed in the Electrical Characteristics, and any transient
current required for switching. The logic device can only sink as much current that can be sunk into its ground
connection. Ensure the maximum total current through GND listed in the Absolute Maximum Ratings is not
exceeded.
The SN74ACT17 can drive a load with a total capacitance less than or equal to 50pF while still meeting all of
the data sheet specifications. Larger capacitive loads can be applied; however, it is not recommended to exceed
50pF.
The SN74ACT17 can drive a load with total resistance described by RL ≥ VO / IO, with the output voltage and
current defined in the Electrical Characteristics table with VOH and VOL. When outputting in the HIGH state, the
output voltage in the equation is defined as the difference between the measured output voltage and the supply
voltage at the VCC pin.
Total power consumption can be calculated using the information provided in CMOS Power Consumption and
Cpd Calculation.
Thermal increase can be calculated using the information provided in Thermal Characteristics of Standard Linear
and Logic (SLL) Packages and Devices.

CAUTION
The maximum junction temperature, TJ(max) listed in the Absolute Maximum Ratings, is an additional
limitation to prevent damage to the device. Do not violate any values listed in the Absolute Maximum
Ratings. These limits are provided to prevent damage to the device.

8.2.1.2 Input Considerations

Input signals must cross to be considered a logic LOW, and to be considered a logic HIGH. Do not exceed the
maximum input voltage range found in the Absolute Maximum Ratings.
Unused inputs must be terminated to either VCC or ground. The unused inputs can be directly terminated if the
input is completely unused, or they can be connected with a pull-up or pull-down resistor if the input will be used
sometimes, but not always. A pull-up resistor is used for a default state of HIGH, and a pull-down resistor is used
for a default state of LOW. The drive current of the controller, leakage current into the SN74ACT17 (as specified
in the Electrical Characteristics), and the desired input transition rate limits the resistor size. A 10kΩ resistor
value is often used due to these factors.
Refer to the Feature Description section for additional information regarding the inputs for this device.
8.2.1.3 Output Considerations
The positive supply voltage is used to produce the output HIGH voltage. Drawing current from the output will
decrease the output voltage as specified by the VOH specification in the Electrical Characteristics. The ground
voltage is used to produce the output LOW voltage. Sinking current into the output will increase the output
voltage as specified by the VOL specification in the Electrical Characteristics.
Push-pull outputs that could be in opposite states, even for a very short time period, should never be connected
directly together. This can cause excessive current and damage to the device.
Two channels within the same device with the same input signals can be connected in parallel for additional
output drive strength.
Unused outputs can be left floating. Do not connect outputs directly to VCC or ground.
Refer to the Feature Description section for additional information regarding the outputs for this device.

8.2.2 Detailed Design Procedure

1. Add a decoupling capacitor from VCC to GND. The capacitor needs to be placed physically close to the
device and electrically close to both the VCC and GND pins. An example layout is shown in the Layout
section.
2. Ensure the capacitive load at the output is ≤ 50pF. This is not a hard limit; by design, however, it will optimize
performance. This can be accomplished by providing short, appropriately sized traces from the SN74ACT17
to one or more of the receiving devices.
3. Ensure the resistive load at the output is larger than (VCC / IO(max))Ω. Doing this will prevent the maximum
output current from the Absolute Maximum Ratings from being violated. Most CMOS inputs have a resistive
load measured in MΩ; much larger than the minimum calculated previously.
4. Thermal issues are rarely a concern for logic gates; the power consumption and thermal increase, however,
can be calculated using the steps provided in the application report, CMOS Power Consumption and Cpd
Calculation.

8.3 Power Supply Recommendations

The power supply can be any voltage between the minimum and maximum supply voltage rating located in
the Recommended Operating Conditions. Each VCC terminal should have a good bypass capacitor to prevent
power disturbance. A 0.1μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass
capacitors to reject different frequencies of noise. The 0.1μF and 1μF capacitors are commonly used in parallel.
The bypass capacitor should be installed as close to the power terminal as possible for best results.
8.4 Layout
8.4.1 Layout Guidelines
• Bypass capacitor placement
– Place near the positive supply terminal of the device
– Provide an electrically short ground return path
– Use wide traces to minimize impedance
– Keep the device, capacitors, and traces on the same side of the board whenever possible
• Signal trace geometry
– 8mil to 12mil trace width
– Lengths less than 12cm to minimize transmission line effects
– Avoid 90° corners for signal traces
– Use an unbroken ground plane below signal traces
– Flood fill areas around signal traces
– For traces longer than 12cm
• Use impedance controlled traces
• Source-terminate using a series damping resistor near the output
• Avoid branches; buffer signals that must branch separately

MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown.
Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board.

(6)
Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part.

Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two
combined represent the entire part marking for that device.
