MAX4751EUD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4751EUD is a low on-resistance, low-voltage, quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.6V to +3.6V supply and features fast switching speeds with tON = 30ns and tOFF = 25ns. The device handles rail-to-rail analog signals while consuming less than 1µW of quiescent power. Key electrical parameters include a maximum on-resistance of 0.9Ω at +3V supply and 2.5Ω at +1.8V supply. It offers an on-resistance flatness of 0.1Ω max at +3V and RON matching of 0.12Ω max at +3V. The component supports 1.8V CMOS logic compatibility and provides high current-handling capacity of 100mA continuous.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EUD corresponds to the TSSOP-14 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the operating voltage range aligns with system requirements before procurement. Check for any specific environmental certifications required for the target application market.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low on-resistance in compact surface-mount packages. The 1.8V CMOS logic compatibility simplifies interface design with microcontrollers. Consider the 100mA continuous current rating for load driving requirements. Evaluate the thermal dissipation characteristics within the TSSOP-14 package for high-current scenarios.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4751 belongs to the MAX475x family of low-voltage analog switches, which includes variants like the MAX4752 and MAX4753. These devices share similar electrical characteristics but may differ in specific configurations or switching behaviors. The MAX4751 specifically focuses on SPST functionality with break-before-make or make-before-break options depending on the variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other members of the MAX475x family such as the MAX4752 or MAX4753, provided pinout and functional differences are accounted for. Verify package compatibility and electrical parameter equivalence before substitution.
