MAX4641EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4641EUA is a monolithic dual single-pole/single-throw (SPST) CMOS analog switch from the MAX4641/MAX4642/MAX4643 series. It operates on a single supply voltage ranging from +1.8V to +5.5V and features two normally open switches. The device guarantees an on-resistance of 4Ω maximum at +5V supply and 8Ω maximum at +3V supply, with a channel-to-channel matching of 0.6Ω and flatness of 1Ω over the entire analog signal range. 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 remain below 0.35nA across the operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for any specific environmental certifications required by your region. Ensure the ordering suffix matches the exact package type needed for your PCB layout. Review the datasheet for absolute maximum ratings to prevent damage during handling and assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low voltage operation down to 1.8V is required alongside high-speed switching capabilities. Consider the MAX4642 if normally closed contacts are needed instead of normally open. Evaluate the MAX4643 for mixed NO/NC configurations. Ensure the application does not exceed the ±50mA continuous current rating per terminal. Verify that the logic input levels are compatible with the system's control voltage at the chosen supply level.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4641/MAX4642/MAX4643 family of high-speed, low-voltage analog switches. These devices share identical electrical characteristics and pinouts but differ in their internal switch configuration. The MAX4641 specifically provides two normally open switches, distinguishing it from the NC variants within the same series. They are designed for portable and battery-powered applications requiring minimal power draw.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include the MAX4642EUA (dual SPST Normally Closed) and MAX4643EUA (one NO, one NC). Both use the same 8-pin µMAX package and share identical electrical specifications. Ensure the replacement matches the required switch state (NO vs NC) for the specific circuit design.
