Signal Switches, Multiplexers, Decoders FAQ

How does the device handle unused differential input pairs?

Unused differential input pairs should be terminated by connecting one input to VCC and the complementary input to GND through a 1kΩ resistor. In this configuration, the corresponding VT pin must be left open.

What is the function of the VREF-AC pins?

These pins provide an output bias voltage equal to VCC minus 1.2V. They are used to bias the circuit when AC-coupling data inputs and should be bypassed with a 0.01µF low ESR capacitor to VCC.
