Analog Devices Inc./Maxim Integrated MAX4713ESE

Overview

MAX4713ESE 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 across ±2.7V to ±5.5V or +2.7V to +11V supplies. It enables robust signal routing in battery-operated test equipment where input overvoltage transients must not damage downstream circuitry.

For engineers reviewing the MAX4713ESE datasheet, MAX4713ESE pinout, MAX4713ESE application, or MAX4713ESE equivalent, key selection criteria include its dual NO/NC configuration, break-before-make timing (5ns typ), fault-clamp behavior during overvoltage events, and compatibility with TTL/CMOS logic across single- and dual-supply operation.

Technical Context

The MAX4713ESE integrates parallel N- and P-channel FETs per channel to achieve low R_ON and flat on-resistance over signal range. Its fault-protection architecture uses independent high- and low-fault comparators that disable the main switch FETs and activate clamp FETs (P2/N2) when NO_/NC_ exceeds V+ or V− by ~150mV.

During fault conditions, COM_ is clamped to the appropriate supply rail (V+ for positive faults, V− for negative faults) while NO_/NC_ becomes high-impedance regardless of logic state. With power off, NO_/NC_ pins remain protected up to ±12V, and all switches default to OFF.

Key Specifications

Pinout & Package

FAQ

What is the maximum fault voltage the MAX4713ESE can withstand with power removed?

The MAX4713ESE provides ±12V fault protection on NO_ and NC_ pins even when V+ and V− are unpowered. This is achieved via internal high-impedance fault-detection circuitry that isolates the pins without drawing supply current. The COM_ pins are not fault-protected and must remain within V− to V+ at all times, including during power-off conditions, to prevent ESD diode conduction.

How does the MAX4713ESE handle overvoltage on NO_ or NC_ pins during normal operation?

When an NO_ or NC_ pin exceeds V+ or V− by approximately 150mV, the MAX4713ESE disables its main switching FETs and activates internal clamp FETs. If the switch is ON, COM_ is actively clamped to V+ (for positive faults) or V− (for negative faults). If the switch is OFF, both NO_/NC_ and COM_ go high-impedance. The clamp can source/sink up to ±15mA, but total terminal current must not exceed ±40mA absolute maximum.

Does the MAX4713ESE support single-supply operation, and what are the logic thresholds at +3V?

Yes, the MAX4713ESE operates from a single +2.7V to +11V supply with V− tied to GND. At +3V supply, the logic thresholds are VIH = +2.0V (minimum) and VIL = +0.6V (maximum), ensuring reliable CMOS-level compatibility. Input leakage remains below ±5µA across temperature, and supply current is only 8–15µA at +25°C, making it ideal for ultra-low-power portable designs.

What is the significance of the break-before-make (BBM) specification for the MAX4713ESE?

The MAX4713ESE guarantees a 5ns typical break-before-make delay between its NO and NC channels-critical for preventing momentary shorts in applications like relay replacement or power-path selection. This BBM timing is intrinsic to the MAX4713's internal logic design and is tested under +2.7V to +5.5V supplies with 300Ω load and 35pF capacitance. It ensures safe transition between alternate signal paths without overlap.

Is the MAX4713ESE pin-compatible with non-fault-protected analog switches?

Yes, the MAX4713ESE shares identical pinout and footprint with industry-standard MAX391/MAX392/MAX393 switches. However, only the NO_ and NC_ pins are fault-protected-the COM_ pins retain standard CMOS switch behavior and require external voltage limiting if exposed to out-of-rail signals. Designers should verify that existing layouts do not route overvoltage-prone signals to COM_ pins before substitution.
