74AHC125 - Quad buffer/line driver

General Description

The 74AHC125; 74AHCT125 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE).

A HIGH on nOE causes the outputs to assume a high impedance OFF-state.

Inputs are overvoltage tolerant.

Key Features

  • Wide supply voltage range from 2.0 V to 5.5 V.
  • Overvoltage tolerant inputs to 5.5 V.
  • High noise immunity.
  • CMOS low power dissipation.
  • Balanced propagation delays.
  • All inputs have a Schmitt-trigger action.
  • Input levels:.
  • For 74AHC125: CMOS level.
  • For 74AHCT125: TTL level.
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A.
  • ESD protection:.
  • HBM: ANSI/ESDA/JEDEC JS-001 class 2.

74AHC125; 74AHCT125 Quad buffer/line driver; 3-state Rev. 8 — 28 April 2025 Product data sheet 1. General description The 74AHC125; 74AHCT125 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A HIGH 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. 2. Features and benefits • Wide supply voltage range from 2.0 V to 5.5 V • Overvoltage tolerant inputs to 5.
