Buffers, Drivers, Receivers, Transceivers FAQ

How does the IOFF circuitry function?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the purpose of the bus hold feature?

Bus hold on all data inputs eliminates the need for external pull-up resistors to hold unused inputs at a valid logic level.
