1. General description
The 74AHC126; 74AHCT126 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. Inputs are overvoltage tolerant. This feature allows the use of these devices as
translators in mixed voltage environments.
2. Features
