Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm that the Pb-Free suffix 'G' indicates NiPdAu lead finish. Ensure compatibility with existing PCB layouts designed for the MC10/100EP57DT series, as this device serves as a pin-for-pin replacement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring high-frequency differential signal multiplexing. It is suitable for designs needing a 4:1 MUX with guaranteed AC parameters over temperature and voltage variations. Consider the 20-pin TSSOP package constraints and termination requirements for PECL/ECL logic levels.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the VBB pins?

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

How does the device handle floating select inputs?

The SEL0 and SEL1 pins include internal 75kΩ pull-down resistors. If left floating, they default to a LOW condition.
