MAX4664CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4664CSE is a quad single-pole single-throw (SPST) CMOS analog switch featuring four 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 5Ω with a channel-to-channel match of 0.5Ω and flatness of 0.5Ω over the signal range. Digital inputs utilize +0.8V and +2.4V logic thresholds for TTL/CMOS compatibility. Key electrical parameters include a maximum off-leakage current of 5nA at +85°C, a typical charge injection of 300pC, and an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail signal handling capability across the full supply voltage range
• Guaranteed low on-resistance matching and flatness for low-distortion performance
• TTL and CMOS compatible control inputs for flexible logic interfacing

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing systems

• Avionics applications requiring reliable switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' confirms the commercial temperature grade and SOIC package. Confirm RoHS compliance status as indicated by the '+' designation in ordering information. Ensure the source document matches the manufacturer's official datasheet for the MAX4664 series to validate pinout and absolute maximum ratings before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed configuration is required for the analog path. Compare against MAX4665 (normally open) and MAX4666 (mixed NO/NC) if different switching states are needed. Verify that the 5Ω on-resistance meets the system's voltage drop requirements and that the 16-pin narrow SOIC package fits the board layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of quad SPST CMOS analog switches. The family shares identical electrical characteristics and pinouts but differs in internal switch configuration. The MAX4664 specifically provides four normally closed switches, distinguishing it from the normally open MAX4665 and the mixed-state MAX4666 within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4665CSE and MAX4666CSE, provided the specific NO/NC configuration aligns with the circuit design. Cross-family replacements require verification of on-resistance, leakage, and supply voltage compatibility.
