Description
General part information
SN55451B Series
The SN5545xB and SN7545xB devices are dual-peripheral drivers designed for use in systems that employ TTL logic. This family is functionally interchangeable with and replaces the SN75450 family and the SN75450A family devices manufactured previously. The speed of the devices is equal to that of the SN75450 family, and the parts are designed to ensure freedom from latch-up. Diode-clamped inputs simplify circuit design.
The SNx5451B, SNx5452B, SNx5453B, and SNx5454B devices are dual peripheral AND, NAND, OR, and NOR drivers, respectively (assuming positive logic), with the output of the logic gates internally connected to the bases of the npn output transistors.
The SN5545xB drivers are characterized for operation over the full military range of –55°C to 125°C. The SN7545xB drivers are characterized for operation from 0°C to 70°C.
