MAX4712CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712CSE 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 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 ensuring TTL and CMOS compatibility. The NO_ and NC_ pins are fault-protected, allowing signals beyond supply rails without excessive current draw.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected analog inputs prevent excessive current when driven beyond supply rails
• Rail-to-rail signal handling capability across the full supply voltage range
• Low on-resistance with guaranteed flatness over the specified signal range
• TTL and CMOS compatible logic inputs for versatile interface options

• 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 package type matches the required board layout, as this part number corresponds to the 16-pin Narrow SOIC. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4712CSE when normally open switching is required within the quad SPST configuration. Ensure the application voltage does not exceed the absolute maximum ratings for the COM_ pin, which lacks fault protection. Consider the power dissipation limits in the SOIC package when designing for high-current loads or elevated ambient temperatures.

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 provides four normally open channels, distinguishing it from the MAX4711 (normally closed) and MAX4713 (mixed). These devices share identical pinouts with industry-standard non-fault-protected switches like the MAX391 series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX391, MAX392, and MAX393 series. Verify that substitute parts meet the specific fault protection requirements, as standard CMOS switches may lack the internal clamping mechanisms present in the MAX4712.
