MAX4641EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4641EUA+ is a dual single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from +1.8V to +5.5V and features low on-resistance of 4Ω maximum at +5V supply. The device provides rail-to-rail analog signal range, fast switching times under 20ns, and extremely low quiescent power consumption below 0.01µW. It offers guaranteed on-resistance flatness of 1Ω and channel matching of 0.6Ω at +5V. Leakage currents are maintained below 0.35nA across the entire temperature range. The component is housed in an 8-pin µMAX package with an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and logic thresholds before integration. Confirm availability through authorized distributors as stock status varies. Validate RoHS compliance requirements for the specific revision. Cross-reference pin configurations to prevent installation errors during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low voltage operation and high speed. Consider the MAX4642 or MAX4643 if normally closed contacts are needed instead of normally open. Evaluate thermal dissipation limits when designing for higher ambient temperatures. Verify that the 8-pin µMAX package fits the available PCB footprint constraints. Check logic level compatibility if operating below +5V supply.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4641/MAX4642/MAX4643 family of high-speed, low-voltage, dual SPST CMOS analog switches. The family differentiates devices based on switch configuration: normally open, normally closed, or mixed. All variants share similar electrical characteristics including low on-resistance and low power consumption. They are designed for portable and battery-powered applications where power efficiency is critical.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include MAX4641EGA and MAX4642EGA. These alternatives offer identical functionality but utilize an 8-pin QFN 3x3 package instead of the µMAX format. Verify pinout compatibility and thermal performance differences between package types before substitution.
