MAX4747ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4747ETE+ is a low-voltage analog switch IC from the MAX4747–MAX4750 family, manufactured by Analog Devices Inc./Maxim Integrated. It features four normally open (NO) single-pole single-throw (SPST) switches housed in a 16-pin Thin QFN package with an exposed pad. The device operates on a single supply voltage ranging from +2V to +11V and supports rail-to-rail analog signal handling. Key electrical parameters include a maximum on-resistance of 50Ω at +3V and 25Ω at +5V, with channel matching limited to 3.5Ω at +3V and 3Ω at +5V. Leakage current is guaranteed below 0.1nA at +25°C, and quiescent power consumption is typically less than 0.5nW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official documentation. Confirm that the exposed pad is correctly identified for thermal and electrical connection requirements. Ensure the ordering suffix matches the specific package type and temperature range intended for your design implementation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require quad SPST switching with extremely low power consumption. Consider the 16-pin TQFN package dimensions for PCB layout constraints. Verify that the application signals remain within the specified supply voltage limits to maintain the guaranteed on-resistance and leakage performance characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4747–MAX4750 series of low-voltage analog switches. While other variants in the series offer different switch configurations such as normally closed or SPDT arrangements, the MAX4747 specifically provides four normally open switches. The ETE+ suffix denotes the 16-pin Thin QFN package with lead-free/RoHS compliance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include the MAX4748ETE+, MAX4749ETE+, and MAX4750ETE+. These parts share identical pinouts and electrical characteristics but differ in internal switch configuration (normally closed or SPDT). Cross-referencing datasheets is required to ensure the switch topology matches the circuit design.
