MAX4711EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711EUE+ 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 component is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the extended temperature grade (-40°C to +85°C) and the TSSOP-16 package configuration. Ensure that the pinout matches the intended design, noting that COM pins lack fault protection while NO/NC terminals are protected. Confirm RoHS compliance status through the manufacturer's environmental declarations before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for analog signals exceeding supply rails. Verify that the maximum on-resistance meets circuit requirements, as it varies with supply voltage and temperature. Ensure the logic input thresholds align with the system's digital control levels. Consider the charge injection and leakage specifications for precision applications requiring minimal signal distortion during switching transitions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4711 variant specifically features four normally closed switches. These devices differ from traditional switches by using parallel FETs for low on-resistance and providing internal clamping during fault conditions. The family maintains pin compatibility with older non-fault-protected CMOS switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with the MAX391, MAX392, and MAX393. When replacing these legacy components, verify that the target application can tolerate the fault-protection behavior where the output clamps to the supply rail during overvoltage events on the input terminals.
