Description
The ULQ2801A-ULQ2804A each contain eight
Darlington transistors with common emitter s an d
integral suppression diodes for inductive loads.
Each Darlington features a peak load curre nt
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 cap ability.
Five versions are available to simplify interfacing
to standard logic families: the ULQ2801A is
designed for general purpose applications with a
current limit resistor; the ULQ2802A has a
10.5 k input resistor and zener for 14-25 V
PMOS; the ULQ2803A has a 2.7 k input resistor
for 5 V TTL and CMOS; the ULQ2804A has a
10.5 k input resistor for 6-15 V CMOS.
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.
