MAX361ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX361ESE is a precision, quad, single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches with low channel on-resistance of less than 85Ω at +25°C and guaranteed matching within 3Ω between channels. The device operates with a single positive supply from +10V to +30V or split supplies ranging from ±4.5V to ±20V. It offers fast switching times, with turn-on time under 250ns and turn-off time under 170ns at +25°C. The package is a 16-pin Narrow SOIC, and the operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'ESE' corresponds to the 16-pin Narrow SOIC package and the -40°C to +85°C temperature range. Confirm that the component is sourced directly from Analog Devices Inc./Maxim Integrated or authorized distributors to ensure authenticity. Check for any recent product change notices or obsolescence announcements related to this part number before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX361ESE when normally closed SPST switching is required in applications demanding low on-resistance and high off-isolation. Ensure the system voltage falls within the specified single-supply (+10V to +30V) or bipolar-supply (±4.5V to ±20V) ranges. Consider the Narrow SOIC package constraints for PCB layout and thermal management. Verify that the logic input levels are compatible with the system's CMOS/TTL standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX361/MAX362 series consists of precision quad SPST analog switches fabricated using an improved 44V silicon-gate process. The MAX361 variant specifically provides four normally closed switches, while the MAX362 offers four normally open switches. Both share identical electrical characteristics regarding on-resistance, leakage, and switching speeds. The series is designed for rail-to-rail analog signal handling with extremely low charge injection and low power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other MAX361 variants such as MAX361CSE (0°C to +70°C), MAX361EPE (-40°C to +85°C, Plastic DIP), and MAX361EJE (-40°C to +85°C, CERDIP). Ensure the substitute matches the required package type and temperature range. Cross-referencing with similar quad SPST analog switches from other manufacturers requires careful verification of pin compatibility and electrical specifications.
