Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry disables all outputs when the supply pin is held at 0 V, preventing damaging current backflow through the device regardless of applied input voltages.

What are the output enable conditions?

Both active low output enable pins, OE1 and OE2, must be low for the outputs to be active. If either pin is high, the outputs enter a high-impedance state.
