MAX4542ESA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542ESA+T is a dual single-pole/single-throw (SPST) analog switch from the MAX4541–MAX4544 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.7V to +12V and features two normally closed (NC) switches. Key electrical parameters include a maximum on-resistance of 60Ω, a maximum charge injection of 5pC, and a positive supply current of 1µA. The device supports bidirectional signal switching with an analog signal range spanning the entire supply voltage. It is housed in an 8-pin SOIC package and is rated for operation within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure compatibility with existing PCB footprints and verify that the component meets all required environmental standards for the intended deployment environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST configuration with normally closed contacts is required. It is appropriate for low-voltage single-supply applications where low power consumption and fast switching speeds are necessary. Consider the 60Ω maximum on-resistance and 5pC charge injection limits relative to the specific signal integrity requirements of the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of precision, dual analog switches designed for low-voltage, single-supply operation. While the MAX4541 offers two normally open switches and the MAX4543 provides mixed NO/NC functionality, the MAX4542 specifically provides two normally closed switches. The MAX4544 variant differs by offering a single-pole/double-throw configuration instead of dual SPST.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541ESA+T and MAX4543ESA+T are pin-compatible alternatives within the same series. Verify that the alternative switch configuration (normally open or mixed NO/NC) aligns with the circuit's logical requirements before substitution.
