Eight Darlington array
Features
■ Eight Darlingtons per package
■ Extended temperature range: -40 to 105 °C
■ Output current to 500 mA
■ Output voltage to 50 V
■ Integral suppression diodes
■ Versions for all popular logic families
■ Output can be paralleled
■ Inputs pinned opposite outputs to simplify
board layout
Description
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 capability.
Five versions are available to simplify interfacing
to standard logic families: the ULQ2801A is
DIP-18
designed for general purpose applications with a
current limit resistor; the ULQ2802A has a 10.5
kΩ input resistor and zener for 14-25V PMOS; the
ULQ2803A has a 2.7 kΩ input resistor for 5 V TTL
and CMOS; the ULQ2804A has a 10.5 kΩ 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.
