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 500mA. The Darlington pairs can be paralleled for higher current capability.

The ULQ2003A-Q1 has a 2.7kΩ series base resistor for each Darlington pair, for operation directly with TTL or 5V CMOS devices. The ULQ2004A-Q1 has a 10.5kΩ series base resistor to allow operation directly from CMOS devices that use supply voltages of 6V to 15V. The required input current of the ULQ2004A-Q1 is below that of the ULQ2003A-Q1.
