MAX4747EUD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4747EUD+T is a low-voltage, quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals. The device features guaranteed on-resistance of 50Ω (max) at +3V and 25Ω (max) at +5V, with channel matching of 3.5Ω (max) at +3V and 3Ω (max) at +5V. Leakage current is guaranteed below 0.1nA at +25°C, and quiescent power consumption is less than 0.5nW (typ). It utilizes TTL/CMOS-compatible logic inputs and offers -84dB crosstalk and -72dB off-isolation at 1MHz. The component is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

• Medical devices such as glucose meters and PDAs

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 extended industrial temperature range of -40°C to +85°C. Ensure the part number includes the '+' symbol to guarantee lead-free and RoHS-compliant manufacturing standards as specified in the official documentation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring quad SPST switching within a low-voltage environment. Verify that the system supply voltage falls between +2V and +11V. Consider the 14-pin TSSOP package constraints for PCB layout. Evaluate if the 50Ω maximum on-resistance meets the signal integrity requirements for the specific analog load being switched.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4747–MAX4750 family of low-voltage analog switches. While the MAX4747 specifically provides four normally open switches, related variants include the MAX4748 (normally closed), MAX4749 (mixed NO/NC), and MAX4750 (dual SPDT). All members share similar electrical characteristics and are available in TSSOP, Thin QFN, and WLP packages.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include MAX4748EUD+, MAX4749EUD+, and MAX4750EUD+. These parts share identical pinouts and electrical specifications but differ in switch configuration (Normally Closed or SPDT). Cross-family replacements require verification of on-resistance and voltage compatibility.
