MAX4700EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4700EPE is a dual SPST CMOS analog switch in a 16-pin Plastic DIP package. It operates from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies, featuring TTL/CMOS-compatible logic inputs via a separate VL pin. The device provides low on-resistance of 1.25Ω max, matched between channels to 0.3Ω max, with flatness over the signal range. It handles Rail-to-Rail analog signals and offers guaranteed break-before-make switching. Key electrical parameters include off-leakage current of 5nA max at +85°C, continuous current handling of ±200mA, and ESD protection exceeding 2kV per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the complete part number including suffixes such as temperature grade and package type when ordering. Confirm that the specific variant matches the required operating temperature range and physical footprint for your PCB design. Check for any recent product change notices or obsolescence announcements from Analog Devices regarding this component family before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4700EPE when break-before-make timing is critical to avoid signal overlap in multiplexed paths. Ensure the supply voltage range aligns with the system's power rails, noting the separate logic supply requirement. Consider the 16-PDIP package constraints if board space is limited, and verify that the ±200mA continuous current rating meets the load requirements of the switched signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4700 belongs to the MAX4680/MAX4690/MAX4700 family of dual SPST analog switches. Unlike the MAX4680 (dual NC) and MAX4690 (dual NO), the MAX4700 combines one normally closed and one normally open switch. This configuration distinguishes it within the series while sharing common low on-resistance and high isolation characteristics typical of Maxim's CMOS analog switch technology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX4680EPE and MAX4690EPE, though their switch configurations differ. For functional equivalence requiring identical break-before-make behavior, no direct cross-model substitute is listed in the provided documentation. Verify compatibility with alternative dual SPST switches if the specific NC/NO mix is not mandatory.
