Analog Devices Inc./Maxim Integrated MAX4713ESE+T

Overview

MAX4713ESE+T 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 not damage downstream circuitry.

For engineers reviewing the MAX4713ESE+T datasheet, MAX4713ESE+T pinout, MAX4713ESE+T application, or MAX4713ESE+T equivalent, this page delivers verified specifications, fault-protection behavior under transient overvoltage, break-before-make timing for channel switching, pin-compatible alternatives, and real-world use cases in avionics backup systems and industrial data-acquisition front-ends.

Technical Context

The MAX4713ESE+T integrates parallel N- and P-channel FETs per channel to achieve low R_ON and rail-to-rail conduction. Its dual comparator-based fault-sensing architecture detects NO_/NC_ voltage excursions beyond V+ or V− by ~150mV, disabling the main switch FETs and activating clamp FETs to limit COM_ output to the appropriate supply rail.

Unlike standard analog switches, it maintains fault protection with zero supply voltage (±12V absolute max on NO_/NC_), supports asymmetric dual supplies (|V+ − V−| ≤ 11V), and provides guaranteed break-before-make timing (t_BBM = 5ns typ at +25°C, +5V supply) to prevent momentary shorting during channel reconfiguration.

FAQ

What is the maximum fault voltage the NO_ and NC_ pins of MAX4713ESE+T can withstand with power removed?

The NO_ and NC_ pins of MAX4713ESE+T tolerate up to ±12V relative to GND with V+ and V− disconnected - a key feature enabling hot-swap resilience and brownout-safe operation. This rating is guaranteed across the full −40°C to +85°C temperature range and does not require external components. The MAX4713ESE+T maintains high-impedance isolation on these pins during such faults, protecting downstream circuitry without drawing excessive current.

How does MAX4713ESE+T handle simultaneous overvoltage on multiple NO_/NC_ pins?

Each NO_ and NC_ pin in MAX4713ESE+T has independent fault-sensing comparators and clamp FETs. Simultaneous overvoltage events on multiple pins trigger individual channel shutdown and output clamping - for example, if NO1 and NC2 both exceed V+, their respective COM1 and COM3 outputs are clamped to V+ independently. No interaction or cascading failure occurs, preserving isolation between unaffected channels. This behavior is confirmed in the device's functional diagrams and fault-response timing waveforms.

Can MAX4713ESE+T operate with asymmetric dual supplies, such as +5V and −3V?

Yes, MAX4713ESE+T supports asymmetric dual supplies as long as |V+ − V−| ≤ 11V and each rail stays within its absolute maximum rating (V+ ≤ +13V, V− ≥ −13V). With +5V and −3V, the fault-protected analog range becomes (−3V −12V) to (+5V +12V), i.e., −15V to +17V on NO_/NC_, while COM_ remains constrained to −3V to +5V. This configuration is explicitly validated in the Electrical Characteristics tables for dual-supply operation.

What is the purpose of the N.C. pin (pin 12) on MAX4713ESE+T, and must it be connected?

Pin 12 on MAX4713ESE+T is designated N.C. (No Connection) and is not internally bonded - it serves no electrical function and must remain unconnected. Neither grounding nor leaving it floating affects device operation, thermal performance, or reliability. This is confirmed in the Pin Description table and Functional Diagrams sections of the official datasheet. Connecting pin 12 could risk mechanical stress or solder bridging with adjacent pins.

Does MAX4713ESE+T provide fault protection on the COM_ pins?

No, MAX4713ESE+T does not provide fault protection on the COM_ pins. They are standard CMOS analog switch terminals with internal ESD diodes to V+ and V−. If a COM_ pin is driven beyond V+ or V− by more than ~0.7V, forward conduction occurs through these diodes, risking excessive current and potential damage. The datasheet explicitly states "COM_ pin is not fault-protected" and warns against exceeding supply rails on COM_. Protection must be implemented externally if COM_ signals may overrange.
