Description

The ULQ2801A-ULQ2805Aeach contain eight darlington transistors with common emitters and integral 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.Outputsmaybe paralleled for higher current capability.

Five versions are available to simplify interfacing to standard logic families : the ULQ2801Ais designed for generalpurpose applications with a current limit resistor ; theULQ2802Ahas a 10.5kW inputresistor and zener for 14-25VPMOS ; theULQ2803Ahas a 2.7kW input resistor for 5V TTL and CMOS ; the ULQ2804A has a 10.5kW input  esistor 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 input- opposite-outputpinout to simplify board layout.
