Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status by checking for the '-E3' designation if halogen-free requirements are mandatory. Ensure the ordering part number matches the exact package type and temperature grade specified in the design documentation before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring fast switching speeds and low on-resistance within a standard SOIC footprint. Verify that the logic control polarity aligns with the system requirements, as the DG411 series uses non-inverting logic. Consider thermal derating guidelines provided in the datasheet for power dissipation calculations under varying ambient temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG411HS family of precision analog switches manufactured by Vishay Siliconix. It serves as a high-performance alternative to older CMOS technologies, offering improved switching speeds and lower power consumption. The HS variant specifically denotes enhanced high-voltage capabilities compared to standard commercial grades.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
