    74LVC541A

    Octal buffer/line driver with 5 V tolerant inputs/outputs; 3-state

    The 74LVC541A is an 8-bit buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high-impedance OFF-state . Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

    Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

    This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

    特性

    • Overvoltage tolerant inputs to 5.5 V

    • Wide supply voltage range from 1.2 V to 3.6 V

    • CMOS low power consumption

    • Direct interface with TTL levels

    • IOFF circuitry provides partial Power-down mode operation

    • Complies with JEDEC standard:

      • JESD8-7A (1.65 V to 1.95 V)

      • JESD8-5A (2.3 V to 2.7 V)

      • JESD8-C/JESD36 (2.7 V to 3.6 V)

    • ESD protection:

      • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

      • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

    • Specified from -40 °C to +85 °C and -40 °C to +125 °C
