MAX351ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX351ESE+ is a precision, quad, single-pole single-throw (SPST) analog switch featuring four normally closed switches. It operates with a single positive supply (+10V to +30V) or split supplies (±4.5V to ±20V). The device offers low on resistance of less than 35Ω, guaranteed channel matching within 2Ω, and flatness over the signal range of ∆3Ω max. Leakage is less than 250pA at +25°C and 6nA at +85°C. Switching times are under 175ns for turn-on and 145ns for turn-off. Charge injection is guaranteed below 10pC. 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 ordering suffix 'ESE+' against official manufacturer documentation to confirm package type and temperature range. Ensure that any alternative part numbers selected maintain identical electrical characteristics and pin configurations to guarantee functional compatibility in existing designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring normally closed analog switching paths. Verify that the required supply voltage falls within the specified single or bipolar ranges. Confirm that the operating temperature environment aligns with the -40°C to +85°C industrial rating defined for the E-grade designation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX351/MAX352/MAX353 family of precision analog switches. While the MAX351 provides four normally closed switches, the MAX352 offers four normally open switches, and the MAX353 combines two of each. All variants share similar electrical performance metrics and fabrication processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other parts from the MAX351/MAX352/MAX353 series with compatible suffixes. Cross-vendor replacements require verification of on-resistance, leakage current, and package dimensions to ensure mechanical and electrical fit.
