Analog Devices Inc./Maxim Integrated MAX4713CUE

Overview

MAX4713CUE from Maxim Integrated is a fault-protected, quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels in a 16-pin TSSOP package. It delivers rail-to-rail signal handling, <25Ω on-resistance at +25°C, ±12V fault protection with power off, and break-before-make timing (tBBM ≤ 20ns at +3V). It enables robust signal routing in battery-operated test equipment where input overvoltage transients must not damage downstream circuitry.

For engineers reviewing the MAX4713CUE datasheet, MAX4713CUE pinout, MAX4713CUE application, or MAX4713CUE equivalent, key selection criteria include its asymmetric fault-protected NO/NC pins, dual- or single-supply operation (+2.7V to +11V or ±2.7V to ±5.5V), guaranteed on-resistance match (≤3Ω), and absence of fault protection on COM pins-requiring external clamping if COM signals exceed supply rails.

Technical Context

The MAX4713CUE integrates parallel N- and P-channel FETs per channel to achieve low R_ON and rail-to-rail conduction. Its dual comparator architecture continuously monitors NO_/NC_ voltage against V+ and V−; a ±150mV excursion triggers immediate switch disable and COM output clamping to the appropriate supply rail via dedicated clamp FETs (P2/N2).

Fault response is asymmetric: turn-on delay is ≤200ns, but recovery after fault removal requires ≥500ns (single supply) or ≥700ns (dual supply) due to internal latch and discharge dynamics. The device remains fault-protected with zero supply bias, supporting hot-swap and maintenance scenarios where power may be absent during signal exposure.

Key Specifications

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for demanding industrial, communications, and computing applications.

The MAX4711/MAX4712/MAX4713 family was engineered specifically for fault-tolerant analog signal routing-delivering integrated overvoltage protection, rail-to-rail performance, and pin compatibility with legacy switches to simplify upgrade paths in test and control systems.

FAQ

What is the maximum fault voltage the MAX4713CUE can withstand on its NO/NC pins with no power applied?

The MAX4713CUE maintains ±12V fault protection on NO_ and NC_ pins even with V+ and V− disconnected. This capability is intrinsic to its internal ESD structure and comparator biasing-no external bias is needed. The specification is guaranteed across the full commercial temperature range (0°C to +70°C) and applies to both MAX4713CUE and its extended-temp variants. Always ensure COM pins remain within V− to V+ to avoid diode conduction.

Does the MAX4713CUE support true bidirectional signal flow, and are all pins equally fault-protected?

Yes, the MAX4713CUE supports bidirectional analog signal flow between NO_/NC_ and COM_ pins under normal operation. However, only NO_ and NC_ pins are fault-protected; COM_ pins lack internal clamping and must never exceed V− or V+-doing so forward-biases internal ESD diodes and risks permanent damage. This asymmetry is intentional and documented in the Absolute Maximum Ratings table.

How does the break-before-make timing of the MAX4713CUE impact its use in redundant signal selection?

The MAX4713CUE guarantees t_BBM ≤ 20ns at +3V supply, ensuring no overlap between NO and NC paths during state transitions. In redundant systems-such as avionics IMU selection-this prevents momentary shorting between primary and backup signal sources. The timing is production-tested and specified across voltage and temperature, making it reliable for fail-safe hardware arbitration without additional timing margining.

Can the MAX4713CUE operate from a single +3.3V supply, and what are the key performance trade-offs?

Yes, the MAX4713CUE operates from +2.7V to +11V single supply (V− = GND). At +3.3V, R_ON increases to ≤100Ω (vs. ≤25Ω at ±5V), t_ON/t_OFF extend to ≤600ns/≤225ns, and fault clamp current drops to 0.5–3.0mA. These are datasheet-guaranteed values-not typicals-and reflect FET channel resistance and drive strength scaling with supply. Designers must verify signal integrity and settling time in low-voltage applications.

Is the MAX4713CUE pin-compatible with non-fault-protected analog switches, and what layout considerations apply?

Yes, the MAX4713CUE shares identical pinout with industry-standard MAX391/MAX392/MAX393 devices. However, only NO_ and NC_ pins inherit fault protection-COM_ pins remain unprotected. Therefore, existing PCBs can accept MAX4713CUE as a drop-in upgrade *only* if COM_ traces are already constrained to V−–V+ and no external overvoltage risk exists on those nodes. No changes are needed to IN_, V+, V−, or GND connections.
