DESCRIPTION

The ULN2801A-ULN2805Aeachcontain 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

least50V inthe offstate.Outputsmaybe paralleled

for highercurrent capability.

Fiveversions are available to simplify interfacing to

standard logic families: the ULN2801A is designed

for generalpurpose applicationswith a current limit

resistor; the ULN2802Ahas a 10.5kΩ inputresistor

and zenerfor 14-25V PMOS; theULN2803Ahas 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

wherehigher output current is required.

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

a copperleadfromandfeaturetheconvenientinput-
