MAX4712EUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712EUE is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection. It operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. The device provides rail-to-rail signal handling with a maximum on-resistance of 25Ω at +25°C and an on-resistance match between channels of 1Ω. Switching times are less than 125ns for turn-on and 80ns for turn-off. It includes fault-protected digital inputs that may exceed the V+ supply rail. The component is housed in a 16-TSSOP package and supports an operating temperature range of -40°C to +85°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 ensures full voltage range operation
• Output clamps to appropriate supply voltages during fault conditions to protect downstream circuitry
• TTL- and CMOS-compatible logic inputs ensure broad interface compatibility

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range of -40°C to +85°C. Confirm the 'UE' suffix indicates the 16-pin TSSOP package. Check for RoHS compliance status as indicated by the '+' suffix if applicable. Ensure the source document matches the manufacturer's official datasheet for the MAX4711/MAX4712/MAX4713 series.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required on analog inputs exceeding supply rails. Choose the E variant for industrial temperature ranges. Verify pin compatibility with existing designs using standard CMOS switches. Consider the 25Ω max on-resistance for signal integrity requirements. Ensure supply voltage stays within the specified single or dual supply limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4712EUE belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. These devices share identical pinouts with industry-standard non-fault-protected switches like the MAX391/MAX392/MAX393. The MAX4712 specifically features four normally open switches, distinguishing it from the MAX4711 (normally closed) and MAX4713 (mixed).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include MAX391, MAX392, and MAX393. Note that these alternatives lack the fault-protection feature found in the MAX4712 series. Direct substitution requires verifying that the application does not rely on the over-voltage protection capabilities.
