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 -55C to 125C and the SG75451B/SG75461/SG75471 drivers are chracterized for operation from 0C to 70C.

Note A. Junction Temperature Calculation: TJ = TA + (PD x JA). Note B. The above numbers for JC are maximums for the limiting
thermal resistance of the package in a standard mounting configuration. The JA numbers are meant to be guidelines for the thermal performance of the device/pcboard 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 -55C TA 125C, and SG75451B/461/471 with 0C TA 70C. Typical values are tested at V CC = 5V, and T A = 25C. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
