Description

This PDF data sheet is for the Allegro ULN2823A High-Voltage High-Current Darlington Array.

Allegro MicroSystems ULN2823A High-Voltage High-Current Darlington Array

Featuring continuous load current ratings to 500 mA for each of the drivers, the Series ULN28xxA highvoltage, high-current Darlington arrays are ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads. Typical power loads totaling over 260 W (350 mA x 8, 95 V) can be controlled at an appropriate duty cycle depending on ambient temperature and number of drivers turned ON simultaneously. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes.
The ULx2823A have series input resistors selected for operation directly with 5 V TTL or CMOS. These devices will handle numerous interface needs – particularly those beyond the capabilities of standard logic buffers.
The ULx2823A will withstand 95 V in the OFF state.
These Darlington arrays are furnished in 18-pin dual in-line plastic packages (suffix “A”). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. Prefix “ULN” devices are rated for operation over the temperature range of -20 deg C to +85 deg C.
