MAX4664CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4664CPE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches with a maximum on-resistance of 5Ω and guaranteed matching to 0.5Ω. The device operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, supporting Rail-to-Rail analog signals. It offers low off-leakage current of 5nA max at +85°C, TTL/CMOS-compatible control inputs, and ESD protection exceeding 2kV per Method 3015.7. The component is housed in a 16-pin Plastic DIP package and functions within an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' corresponds to the 0°C to +70°C commercial temperature grade and 16-pin PDIP package. Confirm that the ordering information matches the manufacturer's current datasheet revision, as product availability and specifications may change. Ensure compliance with RoHS directives if required for the target assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed configuration is required for the analog switching application. Consider the MAX4665 if normally open switches are needed, or the MAX4666 for break-before-make timing requirements. Evaluate the 5Ω on-resistance against the load current and voltage drop constraints of the specific circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of CMOS analog switches. The MAX4664 specifically denotes the variant with four normally closed channels. Other family members include the MAX4665 (four NO switches) and MAX4666 (two NC and two NO switches). The 'C' suffix indicates the commercial temperature range, while 'E' variants support extended industrial temperatures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4665CPE provides identical electrical characteristics but with four normally open switches instead of normally closed.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic input threshold voltage for the MAX4664CPE?

The device has logic thresholds of +0.8V for Logic Low and +2.4V for Logic High, ensuring compatibility with TTL and CMOS logic levels.

Does the MAX4664CPE support break-before-make switching?

No, the MAX4664CPE does not guarantee break-before-make switching times; this feature is specific to the MAX4666 model.

What is the maximum continuous current the switches can handle?

Each switch terminal (COM_, NO_, NC_) can handle a continuous current of ±100mA.
