74LVC2G240

Dual inverting buffer/line driver; 3-state

The 74LVC2G240 is a dual inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH level at pins nOE causes the outputs to assume a high-impedance OFF-state. Schmitt trigger action at all inputs makes the circuit highly tolerant of slower input rise and fall times.

Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of the 74LVC2G240 as a translator in a mixed 3.3 V and 5 V environment.

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

特性

  • Wide supply voltage range from 1.65 V to 5.5 V

  • 5 V tolerant input/output for interfacing with 5 V logic

  • High noise immunity

  • ±24 mA output drive (VCC = 3.0 V)

  • CMOS low power consumption

  • Latch-up performance exceeds 250 mA

  • Direct interface with TTL levels

  • Inputs accept voltages up to 5 V

  • 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
