Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX4643EUA+G24
Analog Switches, Multiplexers, Demultiplexers Overview
The MAX4643EUA+G24 is a monolithic, dual, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply ranging from +1.8V to +5.5V and features low on-resistance of 4Ω maximum at +5V supply. The device provides rail-to-rail analog signal range capability with guaranteed on-resistance flatness of 1Ω and channel matching of 0.6Ω. It offers fast switching times under 20ns while consuming less than 0.01µW of quiescent power. The component includes one normally open and one normally closed switch, with leakage currents below 0.35nA across the entire temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes
Verify the specific ordering suffix G24 against current manufacturer documentation to confirm packaging details and availability status. Confirm RoHS compliance and environmental certifications as required for your application. Check for any product change notices or obsolescence alerts directly from the manufacturer before finalizing procurement plans.
Analog Switches, Multiplexers, Demultiplexers Selection Notes
Select this component when a mixed configuration of normally open and normally closed switches is required within a dual SPST architecture. Ensure the operating voltage aligns with the +1.8V to +5.5V single-supply range. Consider the package size constraints as it utilizes an 8-pin µMAX footprint suitable for space-sensitive designs.
Analog Switches, Multiplexers, Demultiplexers Part Context
This part belongs to the MAX4641/MAX4642/MAX4643 family of high-speed, low-voltage CMOS analog switches. While the MAX4641 contains two normally open switches and the MAX4642 contains two normally closed switches, the MAX4643 specifically combines one of each type in a single package.
Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
Direct functional replacements within the same family include MAX4641EUA and MAX4642EUA, though their switch configurations differ. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
Analog Switches, Multiplexers, Demultiplexers FAQ
What is the difference between the MAX4641, MAX4642, and MAX4643?
The MAX4641 contains two normally open (NO) switches. The MAX4642 contains two normally closed (NC) switches. The MAX4643 contains one normally open (NO) switch and one normally closed (NC) switch.
What is the maximum on-resistance specified for the MAX4643?
The on-resistance is guaranteed to be a maximum of 4Ω at a +5V supply and 8Ω at a +3V supply.
Does the MAX4643 support break-before-make timing?
Yes, the MAX4643 includes a break-before-make feature, which ensures that one switch opens before the other closes to prevent shorting signals during switching transitions.
