MAX4736EGC+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4736EGC+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 turn-on time of 25ns and turn-off time of 20ns, and consumes less than 4μW of quiescent power. It includes break-before-make switching logic and is available in a 12-pin TQFN package.

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 specific package type matches the required footprint, as the MAX4736 family includes μMAX, μDFN, and TQFN options. Ensure the temperature range meets application requirements, as the E-grade variant covers -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and fast switching are critical for signal integrity in low-voltage environments. Consider the 12-pin TQFN package for space-constrained designs requiring exposed pad grounding. Verify logic input compatibility, as the device supports 1.8V CMOS logic levels when powered from a 3V supply.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4736 belongs to the Maxim Integrated line of low-voltage analog switches, designed for portable and battery-operated applications.

The device is part of a broader family including variants with different package options and temperature ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include MAX4736ETC+, MAX4736EUB+, and MAX4736ELB+. These variants share identical electrical characteristics but differ in package type: TQFN, μMAX, and μDFN respectively. Ensure pinout compatibility and thermal management requirements align with the selected replacement.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range supported by the MAX4736?

The MAX4736 supports rail-to-rail analog signals ranging from GND to V+, allowing bidirectional signal passage without significant change in on-resistance.

How does the MAX4736 handle logic input levels?

The digital logic inputs are 1.8V CMOS compatible when using a single 3V supply. Inputs can be driven up to 3.6V regardless of the supply voltage, with VIH typically at 1.4V and VIL at 0.5V for a 3V supply.

What is the break-before-make interval for the MAX4736?

The MAX4736 features a break-before-make switching mechanism with a typical interval of 5ns at +25°C, ensuring that one channel opens before another closes to prevent signal shorting.
