74LVC257A

Quad 2-input multiplexer with 5 V tolerant inputs/outputs; 3-state

The 74LVC257A is a quad 2-input multiplexer; 3-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.

Features and benefits

  • 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

  • Output drive capability 50 Ω transmission lines at 85 °C

  • 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
