Overview
The SN75452BD, produced by Texas Instruments, is a dual-peripheral driver designed 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 SN75452BD is characterized for operation from 0°C to 70°C and is known for its high-speed switching capabilities and freedom from latch-up.
The device features NAND logic inputs and open-collector outputs, making it versatile for various applications. It is particularly suited for systems requiring high-current, high-speed switching and is compatible with standard supply voltages.
