About the Item
Allegro MicroSystems ULN2824LW High-Voltage High-Current Darlington Array
Featuring continuous load current ratings to 500 mA for each of the drivers, the Series ULN28xxLW 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 ULN2824LW have series input resistors for operation directly from 6 V to 15 V CMOS or PMOS logic outputs.
The ULx2824LW will withstand 95 V in the OFF state.
These Darlington arrays are furnished in 18-lead small-outline plastic packages (suffix “LW”). 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.
