3 Description
The ULQ200xA-Q1 devices are high-voltage high-
current Darlington transistor arrays. Each consists of
seven npn Darlington pairs that feature high-voltage
outputs with common-cathode clamp diodes for
switching inductive loads. The collector-current rating
of a single Darlington pair is 500 mA. The Darlington
pairs can be paralleled for higher current capability.
The ULQ2003A-Q1 has a 2.7-kΩ series base resistor
for each Darlington pair, for operation directly with
TTL or 5-V CMOS devices. The ULQ2004A-Q1 has a
10.5-kΩ series base resistor to allow operation
directly from CMOS devices that use supply voltages
of 6 V to 15 V. The required input current of the
ULQ2004A-Q1 is below that of the ULQ2003A-Q1.
