Buffers, Drivers, Receivers, Transceivers FAQ

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

The Ioff circuitry automatically disables the outputs when the supply voltage drops to 0 V, preventing current backflow into the device.

What is the purpose of the input-disable feature?

It allows floating input conditions without causing excessive current draw or oscillation, ensuring stable operation during inactive states.
