MAX4665CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4665CSE is a quad, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 5Ω with guaranteed matching and flatness over the signal range. The device supports rail-to-rail analog signal handling and operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. It includes TTL/CMOS-compatible control inputs and offers ESD protection exceeding 2kV per Method 3015.7. The component is housed in a 16-pin Narrow SO package and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' to confirm the 0°C to +70°C operating temperature range and the 16-pin Narrow SOIC package configuration. Ensure that the application environment remains within these thermal limits. Cross-reference the manufacturer's current documentation for any updates regarding lead-free status or RoHS compliance before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent normally open analog switches are required. It is suitable for applications demanding low distortion and high reliability compared to mechanical relays. Verify that the system voltage requirements align with the specified single or dual supply ranges. Consider the package constraints if board space is limited, as it serves as a compact alternative to traditional switching mechanisms.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of quad analog switches. While all three variants share identical electrical characteristics and pinouts, they differ in switch configuration. The MAX4665 specifically provides four normally open switches, distinguishing it from the MAX4664 which offers four normally closed switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4664 and MAX4666 are pin-compatible alternatives within the same series. The MAX4664 provides four normally closed switches, while the MAX4666 offers two normally open and two normally closed switches with break-before-make timing. These can replace the MAX4665 only if the specific switch state configuration meets the circuit requirements.
