MAX4751EUD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4751EUD+T is a low-voltage, single-supply quad SPST analog switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates from a +1.6V to +3.6V supply and features a maximum on-resistance of 0.9Ω at +3V and 2.5Ω at +1.8V. The device provides fast switching with turn-on times of 30ns and turn-off times of 25ns at +3V. It handles rail-to-rail analog signals and consumes less than 1µW of quiescent power. The component is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix '+T' indicates tape and reel packaging when sourcing components. Confirm that the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the part number matches the 14-pin TSSOP physical footprint required for the target PCB layout. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low on-resistance and fast switching within a narrow single-supply voltage window. The MAX4751 variant specifically provides four normally open switches suitable for general-purpose signal path control. Consider the 1.8V CMOS logic compatibility when interfacing with microcontrollers powered at +3V. Evaluate the thermal dissipation requirements based on the continuous current handling capabilities specified in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4751/MAX4752/MAX4753 family of low-voltage analog switches. The MAX4751 variant distinguishes itself by providing four normally open channels, whereas the MAX4752 offers four normally closed channels and the MAX4753 combines two of each. All variants share identical electrical characteristics and package options, allowing for design flexibility without changing the physical board layout.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4752EUD+T and MAX4753EUD+T, which offer different switch states but maintain identical pinouts and electrical performance. Verify that any replacement maintains the 14-pin TSSOP package dimensions and the specified operating temperature range.
