ULN2003A - Darlington Transistor Array (SEN97H)


ULN2003A 7-Channel High-Current Darlington Array

Ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads, the Series ULN20xxA/L high-voltage, high-current Darlington arrays feature continuous load current ratings to 500 mA for each of the seven drivers. At an appropriate duty cycle depending on ambient temperature and number of drivers turned ON simultaneously, typical power loads totaling over 230 W (350 mA x 7, 95 V) can be controlled. 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 ULN2003A/L has series input resistors selected for operation directly with 5 V TTL or CMOS. The device will handle numerous interface needs — particularly those beyond the capabilities of standard logic buffers.

The ULN2003A/L is a standard Darlington array. Outputs are capable of sinking 500 mA and will withstand at least 50 V in the OFF state. Outputs may be paralleled for higher load current capability.

16-pin DIL package.

TTL, DTL, PMOS, or CMOS-Compatible Inputs
