Product Overview
The SN75451BD is a dual peripheral driver from Texas Instruments, designed for high-current, high-voltage interface applications. Housed in an 8-pin SOIC package, it features two independent drivers with open-collector outputs capable of sinking up to 500 mA per channel. Each driver includes a clamping diode for inductive load protection, making it ideal for driving relays, solenoids, lamps, and other loads in industrial and automotive systems.
