A2803 Product details

HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS

Featuring continuous load current ratings to 500 mA for each of the drivers, the Series ULN28xxA/LW and ULQ28xxA/LW high voltage, 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.

FEATURES
■ TTL, DTL, PMOS, or CMOS Compatible Inputs
■ Output Current to 500 mA
■ Output Voltage to 95 V
■ Transient-Protected Outputs
■ Dual In-Line Package or Wide-Body Small-Outline Package
