MAX4642EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4642EUA is a monolithic, dual, single-pole/single-throw (SPST) CMOS analog switch featuring two normally closed (NC) channels. It operates from a single supply ranging from +1.8V to +5.5V and provides low on-resistance with guaranteed flatness over the entire analog signal range. The device offers fast switching times of less than 20ns while consuming minimal quiescent power. Key electrical characteristics include an on-resistance of 4Ω max at +5V supply, leakage currents below 0.35nA across the temperature range, and excellent AC performance with -97dB crosstalk at 1MHz. 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 and check for obsolescence notices as availability may be limited. Ensure proper ESD handling procedures are followed during storage and installation to maintain device reliability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual normally closed analog switch is required for low-voltage single-supply operation. Consider the MAX4641 if normally open switches are needed instead. Evaluate the package constraints to ensure the 8-pin µMAX footprint fits the design layout requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4641/MAX4642/MAX4643 family of high-speed, low-voltage analog switches manufactured by Analog Devices / Maxim Integrated. The series is designed for portable and battery-powered applications requiring efficient signal routing with minimal power impact.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4641EUA serves as a functional alternative within the same family but features normally open (NO) switches instead of normally closed contacts. Verify logic state requirements before substituting.
