MAX4542CSA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542CSA+ is a precision, dual analog switch designed for single-supply operation from +2.7V to +12V. It features two normally closed (NC) switches with a maximum on-resistance of 60Ω and a typical value of 33Ω at +5V. The device offers low power consumption of 5µW, fast switching speeds with turn-on times up to 150ns and turn-off times up to 100ns, and low leakage currents of 100pA maximum. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CSA+' against official manufacturer documentation to confirm the commercial temperature range and surface-mount SOIC-8 packaging. Ensure compatibility with system voltage requirements and logic levels before finalizing procurement specifications.

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 maximum on-resistance and 150ns turn-on time limits. Verify that the 0°C to +70°C operating range meets environmental constraints compared to extended temperature variants.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. While sharing core electrical characteristics like supply range and power consumption, the MAX4542 is distinguished by its dual normally-closed configuration, contrasting with the normally-open or mixed configurations of other family members.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4542ESA+ serves as a pin-compatible alternative offering an extended industrial temperature range (-40°C to +85°C). Verify functional equivalence regarding the normally-closed channel configuration and ensure the replacement package matches the design constraints.
