Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused or floating data inputs?

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level, eliminating the need for external pull-up resistors.

What is the function of the OE input when set HIGH?

When the Output Enable (OE) input is HIGH, it disables both A and B ports by placing them in a HIGH Z condition.
