MAX4661CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4661CAE is a quad single-pole single-throw (SPST) CMOS analog switch featuring four 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 and an on-resistance match between channels of 0.5Ω. It handles rail-to-rail analog signals with off-leakage current limited to 5nA at +85°C. The component is housed in a 16-pin SSOP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST switches configured as normally closed
• Low on-resistance with guaranteed channel matching and flatness
• Rail-to-rail signal handling capability across the full supply range
• TTL/CMOS-compatible control inputs for flexible logic interfacing

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing in communication systems
• Data acquisition and sample-and-hold circuits
• PBX and PABX system switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CAE' to confirm the 16-pin SSOP package and commercial temperature range. Ensure the design requires normally closed logic states, as this variant differs electrically from the MAX4662 series. Confirm that the application voltage does not exceed the absolute maximum ratings to prevent permanent damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and high channel matching are critical for signal integrity. The MAX4661 is suitable for applications requiring normally closed default states. For break-before-make timing requirements, consider the MAX4663 variant instead. Verify that the board space constraints align with the compact SSOP footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4661/MAX4662/MAX4663 family of 2.5Ω quad analog switches. The MAX4661 specifically provides four normally closed switches, distinguishing it from the MAX4662's normally open configuration. These devices serve as solid-state alternatives to mechanical relays, offering lower power consumption and higher reliability in switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4662CAE offers identical electrical characteristics but features normally open switches instead of normally closed ones.
