MAX4711ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711ESE 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 and guarantees on-resistance flatness over the specified signal range. 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 Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the 'SE' designation corresponds to the 16-pin Narrow SOIC package. Ensure the component meets RoHS compliance requirements if applicable to the project specifications. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or lifecycle changes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required on analog input pins to prevent damage from overvoltage conditions. The MAX4711 specifically offers four normally closed switches, distinguishing it from the normally open MAX4712. Consider the low on-resistance and fast switching speeds for high-frequency signal routing applications requiring minimal signal distortion.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4711 is part of the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. These devices share identical pinouts with industry-standard non-fault-protected CMOS switches like the MAX391/MAX392/MAX393, facilitating direct replacements in existing designs while adding robust fault protection capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible with MAX391, MAX392, and MAX393. Verify that the application does not require fault protection on the COM_ pin, as only NO_ and NC_ pins are protected in this family.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are all pins fault-protected?

No, only the NO_ and NC_ pins are fault-protected. The COM_ pins are not fault-protected and should be limited to the supply voltages to avoid damaging internal ESD diodes.

What is the maximum fault voltage allowed on the inputs?

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

How does the device behave during a fault condition?

When a fault occurs, the switch turns off, and the COM_ output is clamped to the same polarity supply as the input signal, preventing voltages beyond the supply rails from reaching the output.
