Overview

2003 THRU 2024 HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 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 ope...
