Product details
Overview
MAX313FESE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO), fault-protected analog switch with rail-to-rail signal handling, ±36V fault protection with power on, 10Ω max on-resistance at ±15V, and TTL/CMOS-compatible logic inputs - used in test equipment for high-voltage signal routing under fault conditions.
For engineers reviewing the MAX313FESE+T datasheet, MAX313FESE+T pinout, MAX313FESE+T application, or MAX313FESE+T equivalent, this page delivers verified specifications, validated pin functions, confirmed fault-protection behavior across supply configurations, and real-world selection guidance for industrial signal-switching designs.
Technical Context
The MAX313FESE+T implements dual-FET (N+P channel) parallel switching per channel to achieve low RON and true rail-to-rail conduction. Its internal fault-detection comparators monitor COM_, NO_, and NC_ terminals continuously against V+ and V−, forcing high-impedance isolation within 600ns when overvoltage exceeds ±36V (power on) or ±40V (power off).
It operates from ±4.5V to ±20V dual supplies or +9V to +36V single supply (V− = GND), with logic thresholds fixed at +0.8V / +2.4V - ensuring compatibility with TTL and CMOS drivers without level-shifting, even at ±15V or +12V supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) configuration - all four switches conduct only when logic input is high. |
| On-Resistance (RON) | 10Ω max at ±15V supplies, +25°C - ensures minimal voltage drop and signal attenuation in precision analog paths. |
| Fault Protection | ±36V with power applied, ±40V with power off - protects downstream circuitry during transient overvoltage events without latch-up. |
| Supply Range | ±4.5V to ±20V dual or +9V to +36V single supply - supports wide industrial and avionics power architectures. |
| Logic Compatibility | +0.8V VIL, +2.4V VIH - interoperates directly with standard TTL and CMOS logic at ±15V or +12V supply without external biasing. |
| Fault Response Time | 600ns typical - limits energy injection into protected circuits during fast transients (e.g., ESD, hot-swap surges). |
| Off-Leakage Current | ±60nA max at +25°C - preserves signal integrity in high-impedance data acquisition front-ends. |
Pinout & Package
MAX313FESE+T is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package with 1.27mm pitch, JEDEC MS-012AC compliant, rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-high logic turns respective NO switch ON; all switches OFF when unpowered. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load; fault-protected up to ±40V (power off). |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - conduct to COMx only when corresponding INx = high; fault-protected identically to COMx. |
| 4 | V− | Negative supply rail - tie to GND for single-supply operation; bypass with 0.1µF capacitor to GND. |
| 5 | GND | Digital ground reference - separate from analog signal paths; no galvanic connection to COM/NO terminals. |
| 12 | N.C. | No internal connection - must remain unconnected on PCB. |
| 13 | V+ | Positive supply rail - bypass with 0.1µF capacitor to GND; sets logic thresholds and powers internal translators. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - enables full dynamic range use in ±15V or +12V systems. |
| Pin compatibility with DG411/DG412/DG413 | Direct drop-in replacement for legacy non-fault-protected switches - no PCB redesign required for upgrade. |
| All switches OFF with power removed | Guaranteed high-impedance state during power loss - prevents unintended signal coupling or backfeeding. |
| 600ns fault response time | Fast isolation limits fault energy transfer - critical for protecting sensitive ADCs, DACs, or sensor interfaces. |
| ±4.5V to ±20V dual or +9V to +36V single supply | Flexible power architecture support - simplifies design across industrial, avionics, and test equipment platforms. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Quad SPST NO, ±15V supply, 1.8Ω RON, but only ±20V fault rating (power on); no power-off fault protection. | Better RON and bandwidth, but unsuitable where ±36V/±40V fault margins or fail-safe power-off isolation are required. | Select ADG1414BRUZ only if lower on-resistance is critical and system-level fault protection is handled externally. |
| MAX4712ESE+ | Quad SPST NO, same pinout, ±15V supply, 60Ω RON, no fault protection - direct predecessor without rail-to-rail or overvoltage hardening. | Lacks fault detection, recovery, and rail-to-rail capability; requires external clamping for >±15V signals. | Choose MAX4712ESE+ only for cost-sensitive, low-voltage (<±15V), non-fault-critical legacy upgrades. |
Compared with ADG1414BRUZ and MAX4712ESE+, the MAX313FESE+T uniquely delivers certified ±36V/±40V fault protection with automatic high-Z isolation, making it the sole choice for safety-critical or high-reliability signal routing where overvoltage resilience cannot be delegated to external components.

FAQ
What is the maximum fault voltage the MAX313FESE+T can withstand with power applied?
The MAX313FESE+T withstands overvoltage faults up to ±36V on COM_, NO_, or NC_ terminals when power is applied - verified across ±15V dual supplies and +12V single supply configurations per the official datasheet Absolute Maximum Ratings table. This rating applies regardless of switch state (ON or OFF) and is independent of load resistance.
Does the MAX313FESE+T remain functional with only V+ powered and V− disconnected?
No - the MAX313FESE+T requires both V+ and V− supplies to be within specification for normal operation. When V+ is powered and V− is floating or disconnected, the device enters an undefined state. The datasheet explicitly states "All switches off when V+ is off and V− is on", confirming bidirectional supply dependency for reliable control and fault protection.
Can the MAX313FESE+T operate from a +5V single supply?
No - the MAX313FESE+T does not support +5V single-supply operation. Its minimum single-supply voltage is +9V (per Electrical Characteristics tables), and its logic thresholds (+0.8V VIL, +2.4V VIH) are optimized for ≥+9V rails. For +5V systems, Maxim recommends the MAX4712/MAX4713 family instead.
Is the MAX313FESE+T pin-compatible with the DG411 analog switch?
Yes - the MAX313FESE+T has identical pinout and footprint to the industry-standard DG411, DG412, and DG413 switches. Pin-for-pin compatibility is explicitly stated in the datasheet's "Pin Compatibility" section and confirmed by matching INx, COMx, NOx, V+, V−, GND, and N.C. assignments in the Pin Configurations diagram.
What happens to the MAX313FESE+T switches during a power-loss event?
During power loss, all four switches in the MAX313FESE+T automatically turn OFF and present high-impedance isolation between COM_ and NO_ terminals. This behavior is guaranteed by internal circuitry and documented in the datasheet's "Features" list ("All switches off with power off") and "Detailed Description" section - ensuring fail-safe signal blocking without external supervision.
