MAX4712EUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712EUE+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 of 25Ω (max) at +25°C with guaranteed flatness over the signal range. Switching times are less than 125ns for turn-on and 80ns for turn-off. It includes TTL and CMOS compatible logic inputs and offers ±12V fault protection when powered off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected analog inputs prevent excessive current draw when signals exceed supply rails.
• Rail-to-rail signal handling capability allows operation across the full supply voltage range.
• Output clamps to appropriate supply voltages during fault conditions to protect downstream circuitry.
• Pin-compatible with industry-standard MAX391/MAX392/MAX393 devices.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the 'E' suffix indicates an extended temperature range of -40°C to +85°C. Confirm the 'UE' package corresponds to the 16-pin TSSOP form factor. Ensure the '+T' designation matches the required reel packaging specifications for automated assembly processes before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring fault protection against input voltages exceeding supply rails. Verify that the 25Ω maximum on-resistance meets system impedance requirements. Ensure the operating environment falls within the specified -40°C to +85°C temperature range for the E-grade variant.

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 switches, distinguishing it from the MAX4711 (normally closed) and MAX4713 (mixed configuration). These devices share identical pinouts and core functionality.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX391, MAX392, and MAX393 series. Note that these alternatives may lack the specific fault-protection features inherent to the MAX4712. Verify functional equivalence regarding on-resistance and switching speeds before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the fault protection mechanism function?

When analog inputs exceed supply rails by approximately 150mV, the switch turns off internally. The output clamps to the same polarity supply as the input, preventing excessive current flow and protecting downstream electronics.

Are the COM_ pins fault-protected?

No, the COM_ pins are not fault-protected. Signals on COM_ exceeding V+ or V- are clamped by internal diodes, which may conduct high currents if limits are exceeded.

What is the logic compatibility of the digital inputs?

All digital inputs have +0.8V to +2.4V logic thresholds, ensuring compatibility with both TTL and CMOS logic standards when using appropriate supply voltages.
