Analog Devices Inc./Maxim Integrated MAX4713EUE+

Overview

MAX4713EUE+ from Maxim Integrated is a fault-protected, quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, 25Ω max on-resistance at +25°C, ±12V fault protection with power off, and rail-to-rail signal handling from +2.7V to +11V single supply or ±2.7V to ±5.5V dual supply. It enables robust signal routing in battery-operated test equipment where input overvoltage transients must be contained without damaging downstream circuitry.

For engineers reviewing the MAX4713EUE+ datasheet, MAX4713EUE+ pinout, MAX4713EUE+ application, or MAX4713EUE+ equivalent, key selection criteria include fault-protection voltage thresholds under single/dual supply, break-before-make timing for channel switching integrity, on-resistance match between NO/NC pairs, COM pin leakage under fault conditions, and compatibility with TTL/CMOS logic levels across supply ranges.

Technical Context

The MAX4713EUE+ integrates parallel N- and P-channel FETs per switch to achieve low R_ON and rail-to-rail conduction. Its dual comparator architecture continuously monitors NO_/NC_ pins against V+ and V−; exceeding either rail by ~150mV triggers automatic shutdown of the main FETs and activation of clamp FETs (P2/N2) to limit COM output to the appropriate supply rail.

Fault response is asymmetric: positive faults clamp COM to V+, negative faults clamp to V−, with ±15mA clamp current capability. During power-off, NO_/NC_ terminals remain high-impedance up to ±12V, while COM pins retain no fault protection and rely on external diode clamping if driven beyond V+/V−.

Key Specifications

Pinout & Package

MAX4713EUE+ is housed in a 16-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch), rated for -40°C to +85°C operation. Pin functions are identical across MAX4711/MAX4712/MAX4713 families, enabling layout reuse where fault-protection requirements align.

FAQ

What is the maximum fault voltage the MAX4713EUE+ can withstand on NO_/NC_ pins with power removed?

The MAX4713EUE+ maintains ±12V fault protection on NO_ and NC_ pins even when V+ and V− supplies are disconnected. This is achieved through internal high-impedance fault-sensing circuitry that remains active without bias, allowing safe connection to unpowered circuits or hot-swapped modules without risk of latch-up or damage. The MAX4713EUE+ datasheet specifies this under "Fault-Protected Analog Signal Range (Power Off)".

How does the MAX4713EUE+ handle simultaneous overvoltage on multiple NO_/NC_ pins?

The MAX4713EUE+ independently monitors each NO_ and NC_ pin using dedicated comparators. If multiple inputs exceed their respective supply rails, all affected channels shut down and clamp their COM outputs to the corresponding supply rail (V+ for positive faults, V− for negative). There is no interaction or cascading failure - each channel operates autonomously, preserving isolation integrity across the quad switch array. This behavior is confirmed in the "Detailed Description" section of the MAX4713EUE+ datasheet.

Can the MAX4713EUE+ operate reliably with a +3.3V single supply, and what are the key trade-offs?

Yes, the MAX4713EUE+ supports +3.3V single supply (within its +2.7V to +11V range), but R_ON increases to 75Ω max and t_ON/t_OFF slow to 600ns/225ns typical. Logic thresholds shift to VIH = +2.0V and VIL = +0.6V. These values are fully characterized and guaranteed across −40°C to +85°C. The MAX4713EUE+ remains functional and fault-protected at +3.3V, making it suitable for portable medical and IoT edge devices where low voltage and power efficiency are prioritized over speed.

Why is the COM pin not fault-protected in the MAX4713EUE+, and how should it be used safely?

The COM pins in the MAX4713EUE+ lack internal fault protection because they connect directly to the switched analog path and are referenced to system ground or load impedance. Exceeding V+ or V− on COM forward-biases internal ESD diodes, risking permanent damage. To use safely, ensure COM signals stay within V− to V+ at all times - either by limiting source voltage, adding external clamps, or using the MAX4713EUE+ only in configurations where COM is driven by protected sources. This limitation is explicitly stated in Note 1 of the MAX4713EUE+ Absolute Maximum Ratings table.

Is the MAX4713EUE+ pin-compatible with non-fault-protected switches like the MAX393, and what design cautions apply?

Yes, the MAX4713EUE+ shares identical pinout and footprint with MAX391/MAX392/MAX393, enabling drop-in replacement. However, only NO_ and NC_ pins inherit fault protection - COM, IN, V+, V−, and GND retain standard CMOS behavior. Designers must verify that existing layouts do not route unprotected signals to NO_/NC_ pins, and confirm that downstream circuitry can tolerate the MAX4713EUE+'s automatic clamp action (e.g., avoid connecting COM to high-impedance nodes that could saturate during clamping). These considerations are detailed in the "Pin Compatibility" section of the MAX4713EUE+ datasheet.
