MAX4666EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4666EPE is a quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It integrates two normally closed and two normally open switches, ensuring guaranteed break-before-make switching times. The device operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 5Ω, an on-resistance match between channels of 0.5Ω max, and an on-resistance flatness of 0.5Ω max over the specified signal range. Off-leakage current is limited to 5nA maximum at +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates two normally closed and two normally open SPST switches within a single quad configuration.
• Guarantees break-before-make switching times to prevent signal shorting during transitions.
• Supports Rail-to-Rail analog signal handling across wide supply voltage ranges.
• Features TTL/CMOS-compatible control inputs for direct interfacing with standard logic families.

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing systems
• PBX and PABX telecommunications systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EPE' corresponds to the -40°C to +85°C temperature range and 16-pin Plastic DIP package. Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Ensure the source documentation matches the manufacturer's official datasheet specifications for the MAX4666 series.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when break-before-make timing is critical to avoid signal overlap between switched paths. The dual supply capability allows for bipolar signal processing, while the single supply option simplifies power management. Verify that the 5Ω on-resistance and 5nA leakage current meet the distortion and isolation requirements of the specific application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4666EPE belongs to the MAX4664/MAX4665/MAX4666 family of 5Ω quad SPST CMOS analog switches. While the MAX4664 offers four normally closed switches and the MAX4665 provides four normally open switches, the MAX4666 uniquely combines two of each type. This family serves as a solid-state alternative to mechanical relays in applications requiring low power consumption and high reliability.
