DESCRIPTION

The SG5541B/SG55461/SG55471 (SG75451B/SG75461/SG75471) se-

ries of dual peripheral Positive-AND drivers are a family of versatile

devices designed for use in systems that employ TTL or DTL logic. This

family of drivers are direct replacements for the Texas Instruments

SN55451B/61/71 (SN75451B/61/71)series. Diode-clamped inputs sim-

plify circuit design. Typical applications include high-speed logic buffers,

power drivers, relay drivers, MOS drivers, line drivers, and memory drivers.

The SG55451B/SG55461/SG55471 drivers are characterized for opera-

tion over the full military ambient temperature range of -55°C to 125°C and

the SG75451B/SG75461/SG75471 drivers are chracterized for operation

from 0°C to 70°C.
