Product details
Overview
MAX313FEPE from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO), fault-protected analog switch IC. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply, delivers 10Ω max on-resistance at ±15V, supports rail-to-rail signal handling up to ±36V (power on) or ±40V (power off), and features 600ns typical fault response time. It is used in industrial process control systems for robust signal routing under overvoltage stress.
For engineers reviewing the MAX313FEPE datasheet, MAX313FEPE pinout, MAX313FEPE application, or MAX313FEPE equivalent, this page provides verified technical context, pin-level circuit roles, real-world use-value per application, and two confirmed alternative parts with documented functional and application differences - all grounded in the official MAX312F/MAX313F/MAX314F datasheet Rev 0 (1/03).
Technical Context
The MAX313FEPE implements four independent SPST NO switches using parallel N-channel and P-channel MOSFETs per channel, enabling low RON and true bidirectional rail-to-rail analog signal switching. Its internal architecture includes dual comparators monitoring COM_, NO_, and NC_ terminals against V+ and V− to trigger immediate high-impedance isolation during overvoltage faults.
Fault protection operates symmetrically for both polarities: ±36V with power applied (±15V supplies), ±40V with power removed. All digital inputs accept TTL/CMOS logic thresholds (VIH = +2.4V, VIL = +0.8V) across supply configurations, and the device powers down fully - all switches off - when V+ is unpowered, even if V− remains active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) configuration - all four channels conduct only when logic input is high. |
| On-Resistance (RON) | 10Ω maximum at ±15V supplies and +25°C - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| Fault Protection Range | ±36V on COM_/NO_ with power applied; ±40V with power off - enables safe operation in harsh industrial transients without external clamping. |
| Fault Response Time | 600ns typical - limits fault energy injection into downstream circuitry during fast overvoltage events. |
| Supply Range | ±4.5V to ±20V dual supply or +9V to +36V single supply - supports wide-range industrial and avionics power architectures. |
| Logic Compatibility | TTL- and CMOS-compatible inputs (VIH = +2.4V, VIL = +0.8V) with ±15V or +9V–+15V supplies - eliminates level-shifting in mixed-signal control interfaces. |
| Off-Leakage Current | ±60nA max at +25°C - preserves signal integrity in high-impedance sensor or data acquisition front-ends. |
Pinout & Package
MAX313FEPE is housed in a 16-pin plastic DIP package (0.300" width), rated for -40°C to +85°C operation. Pin layout matches industry-standard DG411/DG412/DG413 and non-fault-protected MAX312/MAX313/MAX314, enabling drop-in replacement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 16, 9, 8) | Logic-control digital inputs | Accept TTL/CMOS-compatible signals to enable/disable respective NO switches; no power-supply sequencing required. |
| COM1–COM4 (Pins 2, 15, 10, 7) | Analog switch common terminals | Signal path hub - connects to load or measurement point; fault-protected up to ±40V with power off. |
| NO1–NO4 (Pins 3, 14, 11, 6) | Analog switch normally open terminals | Open-circuit by default; closes to COMx only when corresponding INx is high; fully fault-protected. |
| V+ (Pin 13) | Positive supply voltage input | Bias source for internal logic and gate drivers; bypass with 0.1µF capacitor to GND for noise immunity. |
| V− (Pin 4) | Negative supply voltage input | Required for dual-supply operation; connect to GND for single-supply mode (+9V to +36V). |
| GND (Pin 5) | Digital ground reference | Reference for logic inputs and internal translators; no galvanic connection to analog signal paths. |
| N.C. (Pin 12) | No connection | Not internally bonded - must remain unconnected on PCB to avoid parasitic coupling or ESD risk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale instrumentation amplifier outputs and DAC buffers. |
| Automatic power-off safety | All switches turn off when V+ is unpowered, regardless of V− state - prevents unintended conduction during brown-out or hot-swap sequences. |
| Pin compatibility with DG411/DG412/DG413 | Enables direct replacement in legacy designs without PCB rework - critical for field-upgrade and obsolescence mitigation. |
| 600ns fault response time | Minimizes transient energy transfer during surge events - reduces need for downstream TVS diodes or RC snubbers. |
| ±40V fault tolerance with power off | Allows safe handling of floating or back-driven signals during maintenance or system shutdown - improves field service reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313FESE | Same electrical specs and pinout, but in 16-pin SOIC package (surface-mount); thermal resistance differs (696mW vs. 842mW dissipation limit). | Suitable for space-constrained, high-density PCBs; not ideal for through-hole prototyping or high-vibration environments. | Select MAX313FESE for automated SMT assembly; choose MAX313FEPE for manual soldering, legacy DIP footprints, or mechanical robustness. |
| ADG413BRZ | Quad SPST NO switch with ±20V analog range, 35Ω RON, no integrated fault protection - requires external ±36V clamping diodes and current limiting. | Used where cost sensitivity outweighs fault resilience; unsuitable for unattended industrial deployments with unpredictable transients. | Choose ADG413BRZ only when fault exposure is controlled and board area allows discrete protection components. |
Compared with MAX313FEPE, MAX313FESE offers identical functionality in a smaller footprint but reduced power handling, while ADG413BRZ lacks on-chip fault protection - requiring additional components to match MAX313FEPE's ±40V power-off survivability and 600ns response.

FAQ
What is the maximum fault voltage the MAX313FEPE can withstand with power removed?
The MAX313FEPE sustains ±40V fault voltage on COM_, NO_, or NC_ terminals with all supplies disconnected - verified per Absolute Maximum Ratings table. This enables safe handling of floating or back-driven signals during maintenance, system shutdown, or hot-swap operations without external protection. The ±40V rating applies regardless of whether V+ or V− is present, and is distinct from the ±36V limit under powered conditions.
Does the MAX313FEPE require power-supply sequencing during startup?
No, the MAX313FEPE does not require power-supply sequencing. Its internal logic-level translators and fault comparators operate correctly regardless of the order in which V+ and V− are applied. This eliminates startup timing constraints in systems with asymmetric power rails or staggered supply ramp rates - a key advantage over many competing analog switches that mandate V− before V+ or vice versa.
Can the MAX313FEPE be used with a single +12V supply?
Yes, the MAX313FEPE supports single-supply operation from +9V to +36V. For +12V use, connect V− to GND (Pin 4 → Pin 5), bypass V+ (Pin 13) and GND with 0.1µF capacitors, and ensure logic inputs meet VIH ≥ +2.4V and VIL ≤ +0.8V. Electrical characteristics including RON (30Ω max) and fault response (200ns typ) are specified and guaranteed under +12V conditions per the datasheet.
How does the MAX313FEPE achieve rail-to-rail signal handling?
The MAX313FEPE achieves rail-to-rail operation via parallel N-channel and P-channel MOSFETs per switch, driven by complementary gate signals derived from V+ and V−. This topology allows conduction from V− to V+ without body-diode limitations or signal clipping - unlike single-FET or transmission-gate switches. The result is distortion-free passage of full-scale analog signals, validated by THD+N < 0.001% at 1kHz with ±15V supplies.
Is the MAX313FEPE pin-compatible with the non-fault-protected MAX313?
Yes, the MAX313FEPE is fully pin-compatible with the MAX313 (and industry-standard DG412). Pin assignments for IN_, COM_, NO_, V+, V−, GND, and N.C. are identical across both families. This allows direct replacement on existing PCBs without layout changes - a core design goal stated in the datasheet's "Pin Compatibility" section - provided thermal and fault-margin requirements of the new design are satisfied.
