Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle mixed voltage systems?

The inputs accept voltages up to 5.5V, allowing the device to be driven by 5V devices while operating on a lower VCC supply such as 3.3V.

What is the function of the OE input?

Each output is disabled (high-impedance state) when its associated Output Enable (OE) input is high. When OE is low, the gate passes data from the A input to the Y output.
