Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the DIR pin?

The DIR pin controls the direction of data flow. A low state directs data from B to A, while a high state directs data from A to B.

How does the OE pin operate?

The OE pin is an active-low output enable. When low, the device functions according to the DIR pin setting. When high, all outputs enter a high-impedance state.
