Quad buffer; 3-state
Rev. 6 — 8 October 2020
Product data sheet
1. General description
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.

[1] This parameter is valid for any VCC between 0 V and 2.1 V, with a transition time of up to 10 ms. From VCC = 2.1 V to VCC = 5 V ± 10 %
a transition time of up to 100 μs is permitted.
[2] Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[3] This is the increase in supply current for each input at 3.4 V.

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Draft — The document is a draft version only. The content is still under
