ULN2003A/L and ULN2023A/L are ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads, the Series ULN2003A/L and ULN2023A/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. ULN2003A/L and ULN2023A/L feature open-collector outputs with integral clamp diodes.

The ULN2003A/L and ULN2023A/L have series input resistors selected for operation directly with 5 V TTL or CMOS.  ULN2003A/L and ULN2023A/L will handle numerous interface needs - particularly those beyond the capabilities of standard logic buffers.
