MAX4666ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4666ESE is a quad single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 5Ω with guaranteed matching and flatness over the signal range. The device supports rail-to-rail analog signal handling and operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. It includes two normally closed and two normally open switches, ensuring break-before-make switching times. Key electrical parameters include a maximum off-leakage current of 5nA at +85°C, TTL/CMOS-compatible control inputs, and an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure the component meets RoHS compliance requirements if applicable to the assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4666ESE when mixed normally open and normally closed channels are required within a single package. Consider this component for designs needing low on-resistance and high isolation. Verify that the supply voltage ranges and logic levels align with the system architecture constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4664/MAX4665/MAX4666 family of quad SPST CMOS analog switches. While the MAX4664 offers four normally closed switches and the MAX4665 provides four normally open switches, the MAX4666 specifically combines two of each configuration to facilitate break-before-make operations.
