Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm package integrity and pin alignment against the 8-uMAX/uSOP specification before PCB assembly. Ensure storage conditions maintain moisture sensitivity level compliance. Cross-reference ordering information with official manufacturer documentation to validate suffix designations and revision levels prior to final procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Evaluate the 35 Ohm on-resistance against system loss requirements and verify compatibility with available control logic voltages. Assess thermal performance based on the specified power dissipation limits within the target operating environment. Consider the 175 ns switching speed relative to application bandwidth needs. Confirm that the 30 mA continuous current rating exceeds peak load demands during operation.
