MAX4542EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542EUA 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 µMAX package. The device offers a maximum on-resistance of 60Ω and low leakage currents of 100pA. Switching speeds include a maximum turn-on time of 150ns and a maximum turn-off time of 100ns. Power consumption is minimized at 5µW, making it suitable for battery-powered applications. The component operates across 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 for the 8-pin µMAX format. Cross-reference datasheet specifications for absolute maximum ratings before implementation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally closed analog switch is required for low-voltage single-supply designs. Consider the 60Ω on-resistance and 150ns switching speed limits relative to signal integrity requirements. Evaluate the 8-pin µMAX footprint constraints during layout planning.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply dual analog switches. While sharing core electrical characteristics with the series, the MAX4542 variant specifically provides two normally closed channels, distinguishing it from the normally open or mixed configurations found in other family members.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX4541ESA and MAX4543ESA. Verify that alternative parts match the required contact state (normally closed vs. normally open) and ensure the replacement package matches the 8-pin µMAX form factor.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4542?

The MAX4542 contains two single-pole/single-throw switches that are normally closed (NC).

Is the MAX4542EUA suitable for high-frequency signal switching?

The device supports switching up to 1MHz with specified crosstalk and off-isolation performance, though switching times are in the nanosecond range.

How does the MAX4542 handle overvoltage protection?

Signals exceeding the supply voltage are clamped by internal diodes; external blocking diodes may be added if current must be limited below 10mA.
