SG55451B/SG55461/SG55471
SG75451B/SG75461/SG75471
DUAL PERIPHERAL POSITIVE-AND DRIVER
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.
