Overview
The SN75451BPS 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 SN75451BPS is characterized for operation from 0°C to 70°C, making it suitable for commercial applications. It features AND logic inputs and is designed to ensure freedom from latch-up, with diode-clamped inputs that simplify circuit design.
