SN55450B - SN55454B, SN75451B - SN75454B
Dual Peripheral Drivers
Series 55450B/75451B dual peripheral drivers are a family of versatile devices designed for use
in systems that employ TTL logic. This family is functionally interchangeable with and replaces the
75450 family and the 75450A family of devices. The speed of 55450B/75451B family is equal to
that of the 75450 family, and the parts have been designed to ensure freedom from latch-up. Diode
clamped inputs simplify circuit design.
Typical applications include high-speed logic buffers, power drivers, relay drivers, lamp drivers, MOS
drivers, line drivers, and memory drivers.
