74VHC14
Hex Schmitt Inverter
Features
General Description
The VHC14 is an advanced high speed CMOS Hex
Schmitt Inverter fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to
equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation. Pin configuration and function are the same as the VHC04 but the inputs have hysteresis between the positive-going and negative-going
input thresholds, which are capable of transforming
slowly changing input signals into sharply defined, jitterfree output signals, thus providing greater noise margin
than conventional inverters.
An input protection circuit ensures that 0 V to 7 V can be
applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.
High Speed: tPD = 5.5 ns (Typ.) at VCC = 5 V
Low Power Dissipation: ICC = 2 A (Max.) at TA = 25C
High Noise Immunity: VNIH = VNIL = 28% VCC (Min.)
Power down protection is provided on all inputs
Low Noise: VOLP = 0.8 V (Max.)

Absolute Maximum Ratings(1)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.

Note:
1. Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired.
The data book specifications should be met, without exception, to ensure that the system design is reliable over its
power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside databook specifications.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors
are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical
and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise.
Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global
problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
