Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm RoHS compliance status and material declarations. Confirm availability through authorized distributors, as standard packaging quantities may vary. Ensure the QFN-8L footprint matches the target PCB layout requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SP3T configuration is required within a compact QFN-8L footprint. Verify that the 1.1 Ohm on-resistance meets the system's signal integrity requirements. Ensure the 1.6 V minimum supply voltage aligns with the available power rails in the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of enhanced analog switches from Vishay Siliconix. These devices are designed for high-performance switching applications requiring low distortion and fast switching speeds. The DG2042 variant specifically provides a single SP3T topology, distinguishing it from dual or quad channel counterparts in the same family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible replacements within the DG20xx series. Verify if alternative packages such as MSOP or TSSOP are available for the same electrical specifications if board space constraints change.
