74AHC126; 74AHCT126

Quad buffer/line driver; 3-state

The 74AHC126; 74AHCT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW on nOE causes the outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

  • Balanced propagation delays
  • All inputs have Schmitt-trigger action
  • Inputs accept voltages higher than VCC
  • Input levels:
    • For 74AHC126: CMOS level
    • For 74AHCT126: TTL level
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
    • CDM JESD22-C101C exceeds 1000 V
  • Multiple package options
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
