DESCRIPTION

The ULQ2801A-ULQ2805Aeach contain eight dar-

lington transistors with common emitters and inte-

gral suppression diodes for inductive loads. Each

darlington features a peak load current rating of

600mA (500mA continuous) and can withstand at

least 50V in the off state. Outputs may be paralleled

for higher current capability.

Five versions are available to simplify interfacing to

standard logic families : the ULQ2801A is designed

for general purpose applications with a current limit

resistor ; the ULQ2802A has a 10.5k

Ω inputresistor

and zener for 14-25V PMOS ; the ULQ2803A has a

2.7k

Ω input resistor for 5V TTL and CMOS ; the

ULQ2804A has a 10.5k

Ω input resistor for 6-15V

CMOS and the ULQ2805A is designed to sink a

minimum of 350mA for standard and Schottky TTL

where higher output current is required.

All types are supplied in a 18-lead plastic DIP with

a copper lead frame and feature the convenient in-

put-opposite-outputpinout to simplify board layout.
