DESCRIPTION

The ULN2801A-ULN2805A each 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 ULN2801A is designed

for general purpose applications with a current limit

resistor ; the ULN2802A has a 10.5kΩ input resistor

and zener for 14-25V PMOS ; the ULN2803A has a

2.7kΩ input resistor for 5V TTL and CMOS ; the

ULN2804A has a 10.5kΩ input resistor for 6-15V

CMOS and the ULN2805A 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 from and feature the convenient input-

opposite-output pinout to simplify board layout.
