Overview
ULQ2801 - ULQ2802 ULQ2803 - ULQ2804 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.
