MAX4736ETC+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4736ETC+T is a dual single-pole/double throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single supply voltage ranging from 1.6V to 4.2V and features low on-resistance of 0.8Ω maximum at V+ = 2.7V. The device supports rail-to-rail analog signal handling, fast switching speeds with tON max of 25ns and tOFF max of 20ns, and consumes less than 4μW quiescent power. It includes break-before-make switching logic and is available in a 12-pin TQFN package measuring 3mm x 3mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix +T indicates tape and reel packaging and + denotes lead-free/RoHS-compliant status. Confirm the component is sourced from authorized distributors to ensure authenticity. Check the datasheet for proper power-supply sequencing requirements and absolute maximum ratings to prevent permanent damage during installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and fast switching are required for single-supply applications. Ensure the operating voltage falls within the 1.6V to 4.2V range. Consider the 12-pin TQFN package size if space constraints exist. Verify logic input compatibility with the system's control voltage levels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Compatible alternatives include the MAX4736EUB+T (10-pin μMAX) and MAX4736ELB+T (10-pin μDFN). These variants offer identical electrical characteristics but differ in physical package dimensions and pin configurations. Ensure mechanical fit and PCB layout compatibility before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum continuous current rating for the analog switches?

The maximum continuous current rating for COM_, NO_, and NC_ pins is ±300mA.

Is the MAX4736ETC+T RoHS compliant?

Yes, the '+' suffix in the part number indicates that the device is lead-free and RoHS compliant.

How does the device handle signals exceeding the supply voltage?

Signals on COM_, NO_, or NC_ exceeding V+ or GND are clamped by internal diodes. Forward current must be limited to the maximum current rating to avoid damage.
