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 during partial-power-down scenarios.

What is the purpose of the two output enable inputs?

OE1 and OE2 are active-low inputs that control the 3-state outputs. If either input is high, all corresponding outputs enter a high-impedance state.
