Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for end-of-life notices as discontinuation may affect long-term availability. Validate package markings against official specifications to prevent counterfeit infiltration during sourcing.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring a single analog switch with low power consumption. Ensure the design accommodates the MSOP-8 package thermal constraints given the 320 mW power dissipation limit. Verify that the required signal voltage levels fall within the specified ±15 V dual supply range. Consider the 18.5 Ohm on-resistance impact on signal integrity for precision circuits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG41x family of CMOS analog switches manufactured by Vishay Siliconix. It serves as the lead-free (E3 suffix) tape-and-reel variant of the DG417LDQ. The DG series is characterized by high speed and low power consumption, distinguishing it from older bipolar switch technologies. It complements other variants like the DG411 and DG419 which offer different channel counts or configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG417BDY-E3 is a documented alternative offering similar electrical characteristics but in an SOIC-8 tube package. Designers must account for pinout compatibility and thermal performance differences when substituting packages. Verify that the replacement meets all voltage and current ratings for the specific application.
