SN75447D TI Peripheral Driver | 8-SOIC | 500mA Output, 50V

Product Overview

The SN75447D 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 four independent Darlington transistor pairs with open-collector outputs, each capable of sinking up to 500 mA and withstanding up to 50 V. This device is ideal for driving relays, solenoids, stepper motors, and incandescent lamps in industrial and automotive applications.
