MAX4665CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4665CSE+ is a quad single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 5Ω. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. The device guarantees an on-resistance match between channels of 0.5Ω max and flatness of 0.5Ω max over the signal range. It handles Rail-to-Rail analog signals with off-leakage current limited to 5nA max at +85°C. Turn-on time reaches 275ns, while turn-off time is 175ns. The component is housed in a 16-pin Narrow SO package and supports TTL/CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' confirms the commercial temperature range of 0°C to +70°C and the 16-pin Narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are required. Ensure the application utilizes single or dual supplies within the specified voltage limits. Verify that the 5Ω on-resistance meets the system's signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of quad analog switches. While the MAX4664 offers normally closed contacts and the MAX4666 provides mixed break-before-make functionality, the MAX4665 specifically features four normally open switches for standard signal path switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4664CSE+ and MAX4666CSE+. These parts share identical pinouts and electrical characteristics but differ in internal switch contact configurations.
