SG55451B/SG55461/SG55471
SG75451B/SG75461/SG75471
DUAL PERIPHERAL POSITIVE-AND DRIVER
DESCRIPTION
The SG5541B/SG55461/SG55471 (SG75451B/SG75461/SG75471) series 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 simplify 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 operation 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.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG55451B/461/471 with -55°C ≤ TA ≤ 125°C, and
SG75451B/461/471 with 0°C ≤ TA ≤ 70°C. Typical values are tested at VCC = 5V, and TA = 25°C. Low duty cycle pulse testing techniques are used
which maintains junction and case temperatures equal to the ambient temperature.)
