MAX4642EUA+G104

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4642EUA+G104 is a monolithic, dual, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply ranging from +1.8V to +5.5V and features two normally closed (NC) switches. The device provides a low on-resistance of 4Ω maximum at +5V supply, with guaranteed on-resistance flatness of 1Ω and channel matching of 0.6Ω. Switching times are fast, with typical turn-on and turn-off times of 18ns and 12ns respectively at +5V. Quiescent power consumption is less than 0.01µW, and leakage currents are below 0.35nA over the entire temperature range. It is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure packaging specifications match design requirements. Validate part number suffixes against current datasheets.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low voltage operation and minimal power draw. Consider the normally closed configuration when designing default state logic. Evaluate thermal dissipation limits if operating near maximum ratings. Compare switching speed requirements against typical performance curves. Ensure supply voltage compatibility within the specified 1.8V to 5.5V range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4641/MAX4642/MAX4643 family of high-speed, low-voltage analog switches. The MAX4642 specifically offers dual normally closed switches, distinguishing it from the MAX4641 (normally open) and MAX4643 (mixed NO/NC). All variants share similar electrical characteristics and package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include MAX4641EUA (normally open) and MAX4643EUA (mixed configuration) within the same package. Cross-reference with other Maxim dual SPST switches like MAX4617 or MAX4619 if pinout compatibility allows.
