Signal Switches, Multiplexers, Decoders FAQ

How does the Bus Enable (BE) pin control the switch state?

The switches are turned ON when the BE input signal is Low. When the BE signal is High, the bus disconnects, placing the outputs in a high-impedance state.

What is the typical input capacitance of the PI3C3245?

The typical input capacitance is 3.5 pF when the input voltage is 0V.
