74LVC2G126

Dual bus buffer/line driver; 3-state

The 74LVC2G126 is a dual buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). 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

  • Wide supply voltage range from 1.65 V to 5.5 V

  • Overvoltage tolerant inputs to 5.5 V

  • High noise immunity

  • ±24 mA output drive (VCC = 3.0 V)

  • CMOS low power consumption

  • IOFF circuitry provides partial Power-down mode operation

  • Latch-up performance exceeds 250 mA

  • Direct interface with TTL levels

  • Complies with JEDEC standard:

    • JESD8-7 (1.65 V to 1.95 V)

    • JESD8-5 (2.3 V to 2.7 V)

    • JESD8-B/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

  • Multiple package options

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