MAX4665ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4665ESE is a quad single-pole/single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 8Ω under single-supply conditions and 5Ω under dual-supply conditions. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. The device provides rail-to-rail signal handling, guaranteed on-resistance matching of 0.5Ω max between channels, and flatness of 1.1Ω max over the specified signal range in single-supply mode. It includes TTL/CMOS-compatible control inputs with logic thresholds at +0.8V and +2.4V. The component supports an operating temperature range of -40°C to +85°C and is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the industrial temperature range (-40°C to +85°C) and the 'S' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status as required by project specifications. Ensure ordering documentation matches the exact part number to avoid confusion with the MAX4664 or MAX4666 variants which have different internal switch configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPST switches are required with low distortion characteristics. It serves as a direct alternative to mechanical relays where board space and reliability are critical constraints. Verify that the application signal levels remain within the absolute maximum ratings relative to the chosen supply voltage configuration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4664/MAX4665/MAX4666 family of quad analog switches manufactured by Maxim Integrated. While sharing identical electrical performance and pinouts, the MAX4665 is distinguished by its four normally open (NO) switches. This contrasts with the MAX4664 which features four normally closed (NC) switches, and the MAX4666 which combines two NC and two NO switches.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4665 and MAX4666?

The MAX4665 contains four normally open (NO) switches, whereas the MAX4666 contains two normally closed (NC) and two normally open (NO) switches.

Does the MAX4665 support break-before-make switching?

No, only the MAX4666 variant guarantees break-before-make switching times. The MAX4665 does not specify this feature.

What are the logic input voltage thresholds?

The device features +0.8V and +2.4V logic thresholds, ensuring compatibility with TTL and CMOS logic standards.
