MAX4542EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542EUA+T is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features two normally closed (NC) switches in an 8-pin µMAX package with an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum on-resistance (RON) of 60Ω and a maximum charge injection of 5pC. The device offers low power consumption of less than 5µW and low leakage currents up to 10nA at +85°C. Switching speeds are specified with a maximum turn-on time of 150ns and a maximum turn-off time of 100ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component marking code 'AAAE' on the top surface to confirm authenticity. Ensure the package matches the 8-pin µMAX outline dimensions provided in the datasheet. Confirm that the ordering suffix '+T' indicates tape and reel packaging rather than tube or cut tape formats.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual normally closed switch topology is required within the MAX454x family. Compare against the MAX4541 (dual NO) and MAX4543 (mixed NO/NC) if different contact states are needed. Verify that the 60Ω maximum RON meets the signal path requirements for the specific application voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4541–MAX4544 series of low-voltage, single-supply analog switches manufactured by Maxim Integrated. The series provides various configurations including SPST and SPDT options in multiple package styles such as SOT23, µMAX, SO, and DIP. The MAX4542 specifically defines the dual normally closed variant within this lineup.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4542CUA+T serves as a commercial grade alternative with a 0°C to +70°C temperature range. Other pin-compatible devices include the MAX323, MAX324, and MAX325 series.
