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.
