Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE0 and OE1 pins?

OE0 and OE1 are active-low output enable inputs. When either pin is HIGH, the associated outputs enter a high-impedance OFF-state.

Are the inputs overvoltage tolerant?

Yes, the inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed voltage environments.
