MAX4712ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712ESE 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 NO_ and NC_ pins are fault-protected, while COM_ pins are not.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected analog inputs allow signals beyond supply rails without excessive current draw

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates an extended temperature range of -40°C to +85°C. Confirm the package type matches the narrow SOIC-16 footprint. Check RoHS compliance status as older revisions may differ. Ensure the ordering code aligns with current manufacturing availability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on input/output terminals is required for low-voltage applications. Compare on-resistance specifications against load requirements. Verify that the digital logic levels match the system's control voltages. Consider the pinout compatibility if replacing legacy non-fault-protected switches in existing designs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4712 specifically contains four normally open (NO) switches. It shares identical pinouts with industry-standard MAX391/MAX392/MAX393 devices, facilitating direct replacements in printed circuit boards where only NO_ and NC_ pins require fault protection.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible with MAX391, MAX392, and MAX393. Note that only NO_ and NC_ pins offer fault protection in these replacements; COM_ pins remain unprotected.
