Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The SN74AUCH16244DGGR features active bus-hold circuitry that holds unused or undriven inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors.

What is the purpose of the Ioff feature?

The Ioff circuitry ensures the device is fully specified for partial-power-down applications by disabling outputs to prevent damaging current backflow through the device when it is powered down.
