Overview
The SN75451BDR 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 SN75451BDR is characterized for operation from 0°C to 70°C and is known for its high-speed switching capabilities and freedom from latch-up. It features diode-clamped inputs that simplify circuit design and is suitable for a variety of applications requiring high-current and high-speed switching.
