MAX4665CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4665CPE is a quad, single-pole/single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It features four normally open switches with a maximum on-resistance of 8Ω and a maximum on-resistance match of 0.5Ω over the signal range. The device supports single-supply operation from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Operating temperature range is specified from 0°C to +70°C. Key electrical parameters include a maximum off-leakage current of 0.5nA at +25°C and a typical turn-on time of 250ns under single-supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail signal handling capability across the full supply voltage range
• Guaranteed low on-resistance flatness for minimal signal distortion
• TTL/CMOS-compatible digital control inputs for logic interfacing

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPE confirms the 16-pin Plastic DIP package and the 0°C to +70°C commercial temperature grade. Ensure the component source matches Analog Devices / Maxim Integrated specifications. Confirm RoHS compliance status as indicated by the plus sign in the part number before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration with normally open contacts is required. The 16-pin DIP package suits through-hole prototyping or manufacturing environments. Verify that the 8Ω maximum 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 low-voltage, high-speed CMOS analog switches. While sharing similar electrical characteristics, the MAX4665 specifically provides four normally open switches, distinguishing it from the MAX4664 which offers normally closed switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4664CPE serves as a functional substitute if normally closed contacts are acceptable instead of normally open. The MAX4666CPE provides mixed NO/NC configurations but guarantees break-before-make timing.
