Description

The ULQ2001, ULQ2003 and ULQ2004 are high

voltage, high current darlington arrays each

containing seven open collector darlington pairs

with common emitters. Each channel rated at

500mA and can withstand peak currents of

600mA. Suppression diodes are included for

inductive load driving and the inputs are pinned

opposite the outputs to simplify board layout.

The versions interface to all common logic

families.

These versatile devices are useful for driving a

wide range of loads including solenoids, relays

DC motors, LED displays filament lamps, thermal

print-heads and high power buffers.

The ULQ2001A/2003A and 2004A are supplied in

16 pin plastic DIP packages with a copper lead-

frame to reduce thermal resistance. They are

available also in small outline package (SO-16) as

ULQ2003D1/2004D1.
