MAX4663EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663EPE+ is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices. 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 +4.5V to +36V supply or dual ±4.5V to ±20V supplies. It includes a separate logic supply pin for TTL/CMOS compatibility, off-leakage current of 5nA max at +85°C, and guaranteed break-before-make switching. The component is housed in a 16-pin Plastic DIP package and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching prevents signal overlap during transitions.
• Rail-to-Rail signal handling capability accommodates full voltage swing ranges.
• Low on-resistance ensures minimal signal attenuation in active paths.
• TTL/CMOS-compatible control inputs simplify interface logic requirements.

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing in communication systems
• Sample-and-hold circuits in data acquisition systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPE+' against the manufacturer's official documentation to confirm the extended temperature range (-40°C to +85°C) and the 16-pin PDIP package configuration. Ensure that the logic supply pin is correctly biased for the intended application voltage to maintain specified electrical performance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are required. The MAX4663 variant specifically provides mixed normally open and normally closed switches with break-before-make timing. Verify that the system power supply voltages remain within the specified limits to prevent latch-up or damage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX466x family of quad analog switches, which also includes the MAX4661 (all NC) and MAX4662 (all NO). The MAX4663 distinguishes itself by combining two NC and two NO switches with guaranteed break-before-make functionality, offering flexibility in multiplexing applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4661EPE+ and MAX4662EPE+. Note that these alternatives lack the mixed NC/NO configuration and break-before-make timing found in the MAX4663. Verify pinout compatibility before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness for the MAX4663?

The on-resistance flatness is guaranteed to be 0.5Ω maximum over the specified signal range.

How does the MAX4663 handle switching transitions?

It features guaranteed break-before-make switching, ensuring one switch opens before the other closes to prevent signal shorting.

Is the logic supply voltage independent of the analog supply?

Yes, a separate logic supply pin allows for TTL/CMOS compatibility regardless of the analog supply voltage level.
