Data Sheet

1. General description
The 74HC126; 74HCT126 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 include clamp diodes. This enables the use of
current limiting resistors to interface inputs to voltages in excess of V
CC
.
