MAX4666CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4666CSE is a quad single-pole single-throw (SPST) CMOS analog switch featuring two normally open and two normally closed 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 8Ω under single-supply conditions and 5Ω under dual-supply conditions, with channel matching limited to 0.5Ω and flatness up to 1.1Ω. It supports rail-to-rail signal handling and includes guaranteed break-before-make switching for the MAX4666 variant. The component utilizes TTL/CMOS-compatible logic inputs and is housed in a 16-pin narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features four independent SPST switches configured as two normally open and two normally closed channels
• Supports rail-to-rail analog signal handling across wide supply voltage ranges
• Provides guaranteed break-before-make switching timing to prevent signal shorting
• Includes internal ESD protection exceeding 2kV per Method 3015.7

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in industrial systems
• Audio-signal routing in communication equipment
• Automatic test equipment requiring current switching
• PBX and PABX system signal paths

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'SE' designation corresponds to the 16-pin narrow SOIC package. Ensure the ordering code matches the exact pinout requirements for the mixed NO/NC configuration before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when mixed normally open and normally closed switching is required within a single package. The MAX4666 is distinct from the MAX4664 (all NC) and MAX4665 (all NO). Verify that the 5Ω to 8Ω on-resistance meets the application's signal integrity requirements compared to lower resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of 5Ω quad SPST CMOS analog switches. While all three share similar electrical characteristics and packaging options, they differ strictly in their internal switch configurations. The MAX4666 specifically integrates two NO and two NC switches to facilitate break-before-make applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4664CSE provides identical specifications but contains four normally closed switches. MAX4665CSE offers four normally open switches. Both are direct pin-compatible replacements if the specific NO/NC mix of the MAX4666 is not functionally required.
