FAQ

How does the Ioff feature benefit the SN74LV139ADGVRE4?

The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.

What is the function of the G input pins?

The active-low enable (G) inputs can be used as data lines in demultiplexing applications or to control the output state.
