| Product List |
The ULN2803 is a high-voltage, high-current Darlington transistor array featuring eight open-collector common-emitter pairs, each capable of handling 500 mA. Designed for driving a wide range of loads, including solenoids, relays, DC motors, and LED displays, these arrays offer high-voltage outputs up to 50V and include output clamp diodes for inductive load driving. The inputs are compatible with various logic types, and the pin configuration simplifies board layout. Available in SOP18 and QFN20(4x4) packages, the ULN2803 is ideal for relay-driver applications and high-power buffering.
