74ABT126D

Quad buffer; 3-state

The 74ABT126 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. 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

  • Supply voltage range from 4.5 V to 5.5 V

  • BiCMOS high speed and output drive

  • Direct interface with TTL levels

  • Quad bus interface

  • 3-state buffers

  • Live insertion and extraction permitted

  • Output capability: +64 mA and -32 mA

  • Inputs are disabled during 3-state mode

  • Latch-up protection:

    • JESD78: exceeds 500 mA
