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 leadframe to reduce thermal resistance. They are
available also in small outline package (SO-16) as
ULQ2003D1/2004D1.
