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 in an 8-pin SO package with an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum on-resistance (RON) of 60Ω and a maximum RON matching between channels of 2Ω at +5V supply. The device exhibits low power consumption of less than 5µW and guarantees a maximum charge injection of 5pC. Switching speeds are specified with a maximum turn-on time (tON) of 150ns and a maximum turn-off time (tOFF) of 100ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the package type and temperature rating. Ensure that the component meets all relevant environmental compliance standards required for the intended deployment environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally closed switch topology is required within a single-supply system. Consider the 60Ω maximum on-resistance and 5pC charge injection limits relative to the signal path requirements. Verify that the 8-pin SO package dimensions fit the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply dual SPST/SPDT analog switches. While other members like the MAX4541 offer normally open configurations, the MAX4542 specifically provides two normally closed switches. This family shares common electrical characteristics such as low leakage and fast switching speeds across various package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4542ESA is pin-compatible with the MAX323, MAX324, and MAX325 series. When evaluating substitutes, verify that the alternative device maintains the same dual NC configuration and operates within the required voltage and temperature ranges.
