SN75477D TI Peripheral Driver | 8-SOIC | 500mA Output, 50V

Product Overview

The SN75477D is a high-voltage, high-current peripheral driver from Texas Instruments, designed to interface between low-level logic circuits and high-power loads. Housed in an 8-pin SOIC package, it integrates two independent drivers with open-collector outputs, capable of sinking up to 500 mA per channel and withstanding up to 50 V. The device features internal clamp diodes for inductive load protection, making it ideal for driving relays, solenoids, lamps, and stepper motors in industrial and automotive applications.
