MAX4663CWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663CWE is a quad single-pole single-throw (SPST) CMOS analog switch featuring two normally open and two normally closed channels. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, with TTL/CMOS-compatible logic inputs via a separate VL pin. The device guarantees a maximum on-resistance of 2.5Ω, matched between channels to 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. The component includes guaranteed break-before-make switching and offers >2kV ESD protection.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching for reliable signal routing
• Rail-to-Rail analog signal handling capability
• TTL/CMOS-compatible control inputs across full supply range

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement
• Avionics test equipment
• ADC systems
• Communication systems
• Audio-signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWE' confirms the industrial temperature range of 0°C to +70°C and the 16-pin Wide SOIC package. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure design compatibility with the required single or dual supply voltage configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and precise channel matching are critical. The MAX4663 is distinct from the MAX4661 (all NC) and MAX4662 (all NO) due to its mixed configuration. Verify that the 2.5Ω on-resistance meets system requirements compared to lower-resistance alternatives if signal integrity is paramount.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4663 belongs to the MAX4661/MAX4662/MAX4663 family of quad SPST CMOS analog switches. These devices are designed as solid-state replacements for mechanical relays, offering lower power consumption, reduced board space, and higher reliability in automatic test equipment and data acquisition applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4661CWE: Identical package and electrical characteristics except all four switches are Normally Closed instead of mixed NO/NC. MAX4662CWE: Identical package and electrical characteristics except all four switches are Normally Open.
