MAX4542ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542ESA+ is a precision, dual analog switch designed for single-supply operation from +2.7V to +12V. It features two normally closed (NC) switches within an 8-pin SO package. Key electrical parameters include a maximum on-resistance of 60Ω and a maximum leakage current of 100pA. The device operates with a supply current of less than 1µA and supports switching speeds with a maximum turn-on time of 100ns and turn-off time of 75ns. It functions reliably across a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official manufacturer documentation to confirm authenticity and specifications. Ensure the ordering suffix matches the required package type and temperature rating. Cross-reference part numbers with authorized distributors to validate availability and compliance with relevant standards before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally closed analog switch is required for low-voltage applications. Consider the 60Ω on-resistance limit and 100pA leakage current for signal integrity requirements. Verify that the operating voltage range of +2.7V to +12V aligns with the system design constraints and that the SOIC-8 package fits the board layout.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4542ESA+ belongs to the MAX4541–MAX4544 family of low-voltage, single-supply dual analog switches. While sharing similar electrical characteristics with other members of the series, it is distinctively configured with two normally closed switches, unlike the normally open or mixed configurations found in other variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541ESA+ and MAX4543ESA+ are pin-compatible alternatives within the same family. The MAX4541ESA+ provides two normally open switches, while the MAX4543ESA+ offers one normally open and one normally closed switch. Verify logic sense inversion when substituting these parts.
