The UDN2981AT is an 8-channel high-voltage, high-current source driver IC designed for interfacing between low-level logic circuitry and higher voltage loads. Each channel can source up to 500 mA and withstand output voltages up to 50 V, making it suitable for driving LEDs, relays, lamps, and solenoids directly from logic signals. Its open-emitter outputs and internal clamp diodes provide protection against inductive load transients, ensuring reliable operation in demanding industrial and automotive environments.
