MAX4679EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4679EPE+ is a quad SPST CMOS analog switch in a 16-pin plastic DIP package. It integrates two normally closed and two normally open switches with guaranteed break-before-make switching. The device operates from single +2.7V to +11V or dual ±2.7V to ±5.5V supplies. Key electrical parameters include a maximum on-resistance of 1.6Ω at ±5V, 0.3Ω channel matching, and 0.4Ω flatness. Off-leakage current is 0.1nA at +25°C. The -3dB bandwidth reaches 66MHz with dual supplies. Logic inputs are TTL/CMOS compatible via a separate VL pin.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates two normally closed and two normally open SPST switches within a single quad configuration.
• Features guaranteed break-before-make switching logic for reliable signal path transitions.
• Supports rail-to-rail analog signal ranges across the full supply voltage spectrum.
• Includes a separate logic supply input allowing independent control of analog and digital domains.

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio signal routing systems
• ADC and data-acquisition systems
• Avionics and communications systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPE+' corresponds to the 16-pin plastic DIP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the ordering documentation matches the manufacturer's part numbering system for Analog Devices / Maxim Integrated components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when mixed NC/NO switching is required without external logic. The separate VL pin allows logic levels to differ from the analog supply. Verify that the 1.6Ω on-resistance meets the signal integrity requirements for the target application bandwidth and current load.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4677/MAX4678/MAX4679 family of low-voltage CMOS analog switches. While the MAX4677 offers four NC switches and the MAX4678 provides four NO switches, the MAX4679 uniquely combines both types. All variants share identical electrical characteristics regarding resistance, leakage, and speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4677EPE+ (four NC) and MAX4678EPE+ (four NO), provided the specific switch configuration aligns with the circuit design requirements.
