MAX4666ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4666ESE+ is a quad single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 5Ω. It integrates two normally closed and two normally open switches, ensuring break-before-make switching times. The device operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. Electrical characteristics include an on-resistance match of 0.5Ω max, flatness of 0.5Ω max, and off-leakage current of 5nA max at +85°C. Turn-on time is 275ns maximum, while turn-off time is 175ns maximum. It utilizes TTL/CMOS-compatible control inputs with logic thresholds of +0.8V and +2.4V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation includes the plus suffix to confirm compliance with RoHS standards. Confirm the package variant matches the required narrow SOIC footprint. Ensure the temperature grade corresponds to industrial specifications if operation outside standard ranges is necessary. Cross-reference the manufacturer's ordering information to validate availability and lead times.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when break-before-make timing is critical to prevent signal overlap between channels. Choose this part over normally open or normally closed variants to utilize mixed switch states within a single package. Verify that the supply voltage requirements align with the specified single or dual rail configurations for optimal performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4664/MAX4665/MAX4666 family of quad analog switches. While sharing identical electrical parameters and pinouts, it differs from the MAX4664 by having four normally closed switches and from the MAX4665 by having four normally open switches. This specific configuration provides a balanced mix of contact states.
