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 VCC.
