MAX351CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX351CSE+ is a precision, quad, single-pole single-throw (SPST) analog switch featuring four normally closed channels. It operates with a single supply from +10V to +30V or split supplies of ±4.5V to ±20V. The device provides an on resistance of less than 35Ω, guaranteed channel matching within 2Ω, and low leakage currents below 6nA at +85°C. Switching times are fast, with turn-on under 175ns and turn-off under 145ns. It utilizes a 44V silicon-gate process for rail-to-rail signal handling and includes ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' against official documentation to confirm the commercial temperature range and narrow SOIC package configuration. Ensure that the ordering details align with the manufacturer's current specifications before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when normally closed analog switching is required alongside high precision and low leakage characteristics. Verify that the operating voltage range and logic levels match the system requirements, as the device supports both single and dual supply configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX351/MAX352/MAX353 family of precision analog switches. While the MAX351 features four normally closed switches, the MAX352 offers four normally open switches, and the MAX353 combines two of each type. All variants share similar electrical performance profiles.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX352CSE+ and MAX353CSE+. These parts maintain identical pinouts and electrical characteristics but differ in their internal switch configurations regarding normally open and normally closed states.
