Buffers, Drivers, Receivers, Transceivers FAQ

How is the 3-state output controlled?

The 3-state output is controlled by the output enable inputs (nOE). When nOE is HIGH, the output assumes a high-impedance OFF-state.

What is the input voltage tolerance?

The inputs are overvoltage tolerant to 5.5 V, which allows the device to be used as a translator between different voltage domains.
