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.
