Overview
The SN75451BD is a dual peripheral driver designed by Texas Instruments for use in systems that employ TTL (Transistor-Transistor Logic) logic. This device is part of the SN7545xB family, which is functionally interchangeable with and replaces the earlier SN75450 and SN75450A families. The SN75451BD is characterized for high-speed switching and is designed to ensure freedom from latch-up, making it suitable for a variety of high-current switching applications.
