Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EN-T1-E4 against official Vishay documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's environmental declaration. Check for obsolescence notices or lifecycle changes directly from Vishay, as availability may be restricted.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8:1 multiplexing function is required within a compact QFN-16 footprint. Ensure the application voltage does not exceed the 13.2 V maximum limit. Verify that the 137 Ohm on-resistance meets the signal integrity requirements of the target circuit. Consider thermal management if operating near the upper temperature limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG945x series of high-speed analog switches from Vishay Siliconix. It shares functional similarities with other members of the family but is distinct in its 8-channel configuration. The E4 suffix typically indicates lead-free composition compliant with RoHS standards.
