MAX4665ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4665ESE+ is a quad single-pole single-throw (SPST) CMOS analog switch featuring four normally open channels. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. The device guarantees a maximum on-resistance of 5Ω with a match and flatness of 0.5Ω over the signal range. It handles rail-to-rail analog signals, offers off-leakage current of 5nA max at +85°C, and includes ESD protection exceeding 2kV per Method 3015.7. TTL/CMOS-compatible inputs ensure logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST switches configured as normally open
• Rail-to-rail signal handling capability across full supply range
• TTL and CMOS compatible digital control inputs
• Guaranteed low on-resistance matching and flatness

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing systems
• PBX and PABX communication systems
• Avionics signal switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component marking against the official datasheet pinout and electrical specifications. Confirm the package type matches the required board layout. Ensure the operating temperature range aligns with system requirements. Check for RoHS compliance status if mandated by local regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when four normally open analog paths are required. Compare on-resistance values against other series members like the MAX4663 or MAX4664 if different contact states or resistance levels are needed. Verify that the voltage thresholds meet the specific logic interface requirements of the controlling circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX466x family of quad analog switches manufactured by Analog Devices / Maxim Integrated. The family includes variants with different contact configurations such as normally closed (MAX4664) or mixed break-before-make (MAX4666). All share similar electrical characteristics regarding resistance and leakage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4664ESE+ serves as a functional substitute if normally closed contacts are acceptable instead of normally open. The MAX4666ESE+ provides mixed NO/NC configuration with guaranteed break-before-make timing.
