Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements for your application. Ensure the ordering suffix matches the required temperature grade and package variant. Request official datasheets and certification documents prior to finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel latchable multiplexer is required for microprocessor interfaces. Verify that the analog signal range fits within the specified supply voltage limits. Consider the 18-Wide SO package dimensions for PCB layout constraints. Ensure the system timing requirements align with the 1.5µs switching speed specifications provided in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG528/DG529 series of 8-channel latchable multiplexers. The E suffix indicates the extended temperature grade (-40°C to +85°C), while W denotes the Wide Small-Outline package. This series is designed to replace older industry-standard multiplexers while offering improved integration through onboard latching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG528EWN+ is pin and electrically compatible with the standard DG528/DG529 and ADG528/ADG529 devices. Verify that substitute parts maintain the same latch functionality and break-before-make characteristics to ensure circuit compatibility.
