Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial-power-down scenarios?

The Ioff circuitry disables the outputs when the supply voltage is 0 V, preventing current backflow into the device and inhibiting damage.

What is the purpose of the input-disable feature?

The input-disable feature allows floating input conditions, ensuring proper device operation even when inputs are not actively driven.
