MAX4602EWE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4602EWE+T is a quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Wide SOIC package. It features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω across the signal range. The device supports rail-to-rail analog signals and operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. Electrical characteristics include a maximum off-leakage current of 2.5nA at +85°C, turn-on time of 250ns, and turn-off time of 350ns. It provides over 2000V ESD protection and maintains TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the Wide SOIC footprint matches the target PCB layout dimensions before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring low distortion and high reliability compared to mechanical relays. Verify that the required analog signal voltage stays within the supported single or dual supply rails. Consider the 2.5Ω on-resistance impact on signal integrity for low-voltage applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4601/MAX4602/MAX4603 family of quad analog switches. While the MAX4601 offers normally closed switches and the MAX4603 combines both types, the MAX4602 specifically provides four normally open channels. All variants share identical electrical performance specifications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4601EWE+ and MAX4603EWE+. These parts share the same package and electrical ratings but differ in switch configuration (normally closed or mixed).
