MAX4711CUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711CUE+T is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features fault protection on the NO_ and NC_ pins, allowing signals to exceed supply rails without excessive current draw. The device operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. Key electrical parameters include a maximum on-resistance of 25Ω at +25°C with a single +5V supply, and turn-on/turn-off times of less than 125ns and 80ns respectively. It utilizes a 16-pin TSSOP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) and '+T' denotes tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the source document matches the exact part number to avoid confusion with non-fault-protected variants.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on analog inputs is required to safeguard downstream circuitry from overvoltage conditions. Verify that the single-supply operation range of +2.7V to +11V aligns with the system power architecture. Consider the 25Ω maximum on-resistance for signal integrity requirements in low-voltage applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4711 variant specifically provides four normally closed (NC) switches, distinguishing it from the MAX4712 (normally open) and MAX4713 (mixed) configurations within the same pin-compatible series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with industry-standard MAX391/MAX392/MAX393 devices. However, direct replacement requires verification that the existing design does not rely on COM_ pin fault protection, as only NO_ and NC_ pins are protected in this family.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are the COM_ pins fault-protected?

No, the COM_ pins are not fault-protected. They act as normal CMOS switch terminals, and exceeding supply voltages on these pins may cause high currents through internal ESD diodes.

What is the fault protection limit for the NO_ and NC_ pins?

The NO_ and NC_ pins offer fault protection up to ±12V relative to ground, regardless of the supply voltage, even when power is removed.

How does the device behave during a fault condition?

When a fault occurs, the input becomes high impedance, and the COM_ output is clamped to the same polarity supply voltage as the input signal, preventing the fault voltage from propagating further.
