Signal Switches, Multiplexers, Decoders FAQ

How does the device handle partial power-down scenarios?

The device includes IOFF circuitry that disables the output, preventing damaging backflow current through the device when it is powered down.

What is the function of the nOE input pins?

The separate output enable inputs (1OE to 4OE) control the state of each switch; the switch is disabled (high-impedance OFF-state) when the corresponding nOE input is HIGH.
