Description:

The 75451N, more formally known as the DS75451N, is a dual peripheral driver IC designed by Texas Instruments (originally National Semiconductor). It’s tailored for interfacing TTL logic with higher voltage/current loads, making it a reliable choice for driving relays, lamps, and other inductive or resistive loads in control systems. With two open-collector drivers and built-in protection, it’s a compact solution for switching applications where robustness and simplicity are key.
