MAX4711EUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711EUE+T is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. The device provides low on-resistance with a maximum of 25Ω at +25°C under dual supply conditions. Switching times are less than 125ns for turn-on and less than 80ns for turn-off. Digital inputs have logic thresholds ensuring TTL and CMOS compatibility. The package is a 16-pin TSSOP.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as the MAX4711 series may be discontinued in certain variants. Confirm the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Ensure the '+T' designation aligns with the required tape-and-reel packaging format rather than tube packaging. Cross-reference the manufacturer's latest obsolescence notices before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring fault protection on analog inputs while maintaining pin compatibility with standard CMOS switches. Verify that the COM_ pins do not require fault protection, as they lack internal clamping diodes for overvoltage. Ensure the load current does not exceed the absolute maximum ratings during normal or fault conditions to prevent device damage.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4711EUE+T belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. This family distinguishes itself by using parallel FETs for low on-resistance and providing robust fault protection on NO_ and NC_ pins. The MAX4711 variant specifically features four normally closed switches, differing from the MAX4712 which has four normally open switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with the MAX391, MAX392, and MAX393. When replacing these non-fault-protected switches, ensure the application does not rely on fault protection for the COM_ pins, as those terminals remain unprotected in the MAX4711 series.

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 can cause high currents through ESD diodes.

What is the maximum fault voltage allowed on the NO_ or NC_ pins?

The maximum fault voltage on the NO_ or NC_ pins is ±12V, even when the power is turned off.

How does the device behave during a fault condition?

During a fault, the input becomes high impedance, and if the switch is on, the output is clamped to the same polarity supply voltage via internal clamp FETs.
