DUAL PERIPHERAL POSITIVE-AND DRIVER
DESCRIPTION
FEATURES
• 300mA output current capability
• High-voltage output
• No output latch-up at 20V
• High speed switching
• TTL or DTL compatible diode-clamped inputs
• Standard supply voltages
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,
powerdrivers, relaydrivers, MOSdrivers, linedrivers, andmemorydrivers.
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.
HIGH RELIABILITY FEATURES
- SG55451B/SG55461/SG55471
♦ Available to MIL-STD-883
♦ Scheduled for MIL-M-38510 QPL listing
♦ LMI level "S"processing available

Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The θJA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.

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.)
