MAX4734EUB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4734EUB+ is a low on-resistance, low-voltage, 4-channel CMOS analog multiplexer operating from a single 1.6V to 3.6V supply. It features fast switching speeds with turn-on and turn-off times of 25ns and 20ns maximum at 3V. The device handles rail-to-rail analog signals and consumes less than 4μW of quiescent power. It offers a maximum on-resistance of 0.8Ω at 3V and 2Ω at 1.8V, with high current handling capacity of 150mA continuous. Available in a space-saving 10-pin μMAX package, it includes break-before-make switching and 1.8V CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Maxim Integrated datasheets to confirm pinout alignment and electrical specifications. Ensure that the 10-pin μMAX package dimensions match your PCB footprint requirements. Check RoHS compliance status if environmental regulations apply to your specific manufacturing process or end-use application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low voltage operation between 1.6V and 3.6V is required alongside minimal power consumption. Consider the 0.8Ω on-resistance for applications demanding high continuous current handling up to 150mA. Verify that the 1.8V CMOS logic interface aligns with your system's control signals without requiring additional level shifting circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4734 series consists of low on-resistance, low-voltage, 4-channel CMOS analog multiplexers. The EUB+ suffix specifically denotes the -40°C to +85°C temperature range and the 10-pin μMAX package format. Other variants include the ETC+ for the 12-pin TQFN package and tape-and-reel options indicated by the 'T' suffix.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX4734ETC+ for the TQFN package variant. Cross-family replacements should be evaluated based on matching channel count, supply voltage range, and on-resistance specifications to ensure functional equivalence in the target circuit design.

Analog Switches, Multiplexers, Demultiplexers FAQ
