Signal Switches, Multiplexers, Decoders FAQ

How does the COM_SEL pin function relative to SEL0 and SEL1?

The COM_SEL pin provides common select control for both channels simultaneously. When active, it overrides individual SEL0 and SEL1 pins, ensuring synchronized switching between Channel 0 and Channel 1.

What is the purpose of the VBB output reference pins?

The VBB pins provide a reference voltage approximately equal to VCC minus 1.4V. They are used to bias unused inverting inputs in single-ended applications or serve as termination points for AC-coupled differential inputs.
