Overview
The SN75451B is a dual-peripheral driver integrated circuit produced by Texas Instruments. It is designed for use in systems that employ TTL (Transistor-Transistor Logic) and is part of the SN7545xB family, which replaces the earlier SN75450 and SN75450A families. This device is characterized for operation from 0°C to 70°C and is functionally interchangeable with its predecessors while ensuring freedom from latch-up. The SN75451B features diode-clamped inputs, which simplify circuit design, and it includes internal logic gates connected to the bases of npn output transistors.
