Translators, Level Shifters FAQ

How does the output enable input function?

A LOW signal on the OE input causes the outputs to assume a high-impedance OFF-state.

What is the maximum input voltage allowed?

Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VDD(A), up to VDD(A) + 0.5 V.
