Description  

designed for general purpose applications with a  

current limit resistor; the ULQ2802A has a 10.5  

k

Ω

input resistor and zener for 14-25V PMOS; the  

ULQ2803A has a 2.7 k

Ω

input resistor for 5 V TTL  

and CMOS; the ULQ2804A has a 10.5 k

Ω

input  

resistor for 6-15 V CMOS.  

The ULQ2801A-ULQ2804A each contain eight  

Darlington transistors with common emitters and  

integral suppression diodes for inductive loads.  

Each Darlington features a peak load current  

rating of 600 mA (500 mA continuous) and can  

withstand at least 50 V in the off state. Outputs  

may be paralleled for higher current capabilit

y

.  

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.  

Five versions are available to simplify interfacing  

to standard logic families: the ULQ2801A is
