Overview
The SN75453BDR is a dual-output driver produced by Texas Instruments, designed for use in systems that employ TTL (Transistor-Transistor Logic) logic. This device is part of the SN7545xB family, which replaces the earlier SN75450 and SN75450A families. The SN75453BDR is characterized for operation from 0°C to 70°C and is functionally interchangeable with its military-grade counterpart, the SN5545xB, which operates over a wider temperature range of –55°C to 125°C.
The device features dual peripheral OR drivers, with the output of the logic gates internally connected to the bases of the npn output transistors. It is designed to ensure freedom from latch-up and includes diode-clamped inputs to simplify circuit design.
