74ABT125 - Quad buffer

General Description

The 74ABT125 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.

This device is fully specified for partial power down applications using IOFF.

Key Features

  • Supply voltage range from 4.5 V to 5.5 V.
  • BiCMOS high speed and output drive.
  • Direct interface with TTL levels.
  • Power-up 3-state.
  • Inputs are disabled during 3-state mode.
  • IOFF circuitry provides partial Power-down mode operation.
  • Latch-up protection exceeds 500 mA per JESD78B class II level A.
  • Quad bus interface.
  • 3-state buffers.
  • Live insertion and extraction permitted.
  • Output capability: HIGH -32.

74ABT125 Quad buffer; 3-state Rev. 9 — 13 March 2023 Product data sheet 1. General description The 74ABT125 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. 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. 2. Features and benefits • Supply voltage range from 4.5 V to 5.
