MAX4712CUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712CUE+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, ensuring guaranteed 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 of +0.8V to +2.4V, ensuring TTL and CMOS compatibility. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of 0°C to +70°C.

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 across the full supply voltage range
• Low on-resistance with guaranteed flatness and channel matching
• All switches automatically turn off when power is removed

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation corresponds to tape-and-reel packaging as per the manufacturer's ordering information. Ensure the source documentation explicitly lists this exact part number variant before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring fault protection against voltages exceeding supply rails. Verify that the required switching speed meets the 125ns turn-on and 80ns turn-off specifications. Ensure the system operates within the supported single or dual supply voltage ranges and accommodates the 16-pin TSSOP footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4712 specifically contains four normally open switches, distinguishing it from the MAX4711 which features normally closed switches. These devices share identical pinouts with industry-standard non-fault-protected CMOS switches like the MAX391 series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with industry-standard MAX391, MAX392, and MAX393 switches. However, direct replacement requires verifying that the NO_ and NC_ pins are utilized for fault protection, as the COM_ pins lack this feature.
