ULN2001 LINEAR INTEGRATED CIRCUIT

3CH DARLINGTON SINK

DRIVER

 DESCRIPTION
The UTC ULN2001 is high-voltage, high-current darlington
transistor arrays. Each consists of three NPN darlington pairs that
feature high-voltage outputs with common-cathode clamp diodes
for switching inductive loads. The collector-current rating of a single
darlington pair is 500mA. All units feature integral clamp diodes for
switching inductive loads.
Applications include relay, hammer, lamp and display (LED)
drivers.
The UTC ULN2001 has a 2.7kΩ series base resistor for each
darlington pair for operation directly with TTL or 5V CMOS devices.

 FEATURES
* Output Current (Single Output): 500mA max
* High Sustaining Voltage Output: 50V min
* Inputs Compatible with Various Types of Logic
* Output Clamp Diodes
* Relay-Driver Applications
