Signal Switches, Multiplexers, Decoders FAQ

How are static logic values established on the input pins?

Static logic zero is achieved by leaving both true and complement inputs unconnected for VCC > 3.0V. Static logic one requires connecting the true input to VCC while leaving the complement input unconnected.

What termination scheme is recommended for the inputs?

Inputs should be terminated with a single resistor connected between the true and complement pins of a given differential input pair.
