MAX4712EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712EUE+ is a fault-protected, low-voltage, quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. The device features rail-to-rail signal handling and guaranteed on-resistance flatness over the specified signal range. Switching times are less than 125ns for turn-on and less than 80ns for turn-off at ±5V supplies. The NO_ and NC_ pins provide fault protection up to ±12V, while the COM_ pin is not fault-protected. Logic inputs are compatible with TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected analog inputs allow signals beyond supply rails without excessive current draw
• Rail-to-rail signal handling capability ensures full voltage range operation
• Output clamps to appropriate supply voltages during fault conditions to protect downstream circuitry
• All switches turn off automatically when power is removed

• Communication Systems
• Signal Routing
• Test Equipment
• Data-Acquisition
• Industrial and Process Control Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'E' indicates an extended temperature range of -40°C to +85°C. Confirm the package type corresponds to the 16-pin TSSOP configuration. Ensure compatibility with existing PCB footprints as these devices are pin-compatible with industry-standard MAX391/MAX392/MAX393 switches. Check RoHS compliance status if required for your manufacturing process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on both normally open and normally closed terminals is required. The MAX4712 specifically provides four normally open switches. Consider the on-resistance variation across different supply voltages and temperatures. Ensure the COM_ pin connections do not exceed supply rails to avoid damage from internal ESD diodes. Verify logic level thresholds match your control interface voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected analog switches. The MAX4712 variant is distinguished by having four normally open (NO) channels, whereas the MAX4711 has four normally closed (NC) channels and the MAX4713 combines two NO and two NC channels. All three share identical pinouts and core electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include MAX391, MAX392, and MAX393. Note that these standard CMOS switches lack the fault-protection feature found in the MAX471x series. Direct substitution requires verifying that the application does not rely on the fault-protection mechanism to safeguard connected circuitry.
