DESCRIPTION

The ULN2801A-ULN2805Aeach contain eight darlington 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 offstate.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 ULN2802Ahas a 10.5k? input resistor and zener for 14-25V PMOS; the ULN2803Ahas a 2.7k?input resistor for 5V TTL and CMOS ; the ULN2804A has a 10.5k?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 fromand featurethe convenient input
