Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the dual output enable inputs?

The dual output enable inputs allow independent control of the eight outputs, enabling flexible bus management and isolation configurations.

How does the supply voltage affect propagation delay?

Propagation delay decreases as supply voltage increases; it is slower at 2 V and faster at 6 V, as specified in the electrical characteristics.
