Overview
The SN75454BP 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, ensuring freedom from latch-up and high-speed switching capabilities. The SN75454B specifically functions as a NOR driver, with its logic gates internally connected to the bases of the npn output transistors.
