Buffers, Drivers, Receivers, Transceivers FAQ

How does the IOFF circuitry function?

The IOFF circuitry disables the outputs to prevent potentially damaging backflow current through the device when it is powered down.

What is the purpose of the bus hold feature?

Bus hold on data inputs ensures that the inputs remain at a defined logic level even when disconnected or floating, preventing undefined states.
