3 Description
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.
