74AHC125; 74AHCT125
Quad buffer/line driver; 3-state
Rev. 6 — 4 September 2023
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
