MAX361CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX361CSE+T is a precision, quad, single-pole single-throw (SPST) analog switch featuring four normally closed channels. It operates with single positive supplies (+10V to +30V) or split supplies (±4.5V to ±20V). The device offers low channel on-resistance of less than 85Ω at +25°C and guaranteed matching within 3Ω between channels. Leakage current remains below 500pA at +25°C. Switching performance includes turn-on times under 250ns and turn-off times under 170ns. The component utilizes a 44V silicon-gate process for rail-to-rail signal handling and CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the narrow SOIC package and commercial temperature range during sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure supply voltage sequencing aligns with absolute maximum ratings to prevent damage. Validate pinout compatibility against existing PCB layouts before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed states are required upon power-up. Compare against the MAX362 if normally open functionality is preferred. Consider the MAX391 series for lower on-resistance requirements. Verify bipolar versus unipolar supply constraints match the target application's signal range and leakage specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX361/MAX362 family of precision analog switches manufactured by Analog Devices/Maxim Integrated. The CSE designation indicates a commercial temperature range variant housed in a 16-pin Narrow SO package. It serves as a monolithic solution for signal routing in mixed-signal systems requiring high isolation and low distortion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX362CSE+T provides identical electrical characteristics but features normally open switches instead of normally closed.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the MAX361CSE+T switches?

The MAX361CSE+T contains four normally closed (NC) switches that connect the COM terminal to the NC terminal when the logic input is low.

How does the MAX361 handle analog signals relative to its supply rails?

It supports rail-to-rail analog signal handling, allowing signals to swing from the negative supply to the positive supply due to its 44V maximum breakdown voltage.

Is the MAX361 compatible with standard logic families?

Yes, it features CMOS logic inputs that provide reduced input loading and are compatible with TTL and CMOS logic levels.
