Product details
Overview
MAX313FESE+TG52 from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) analog switch with fault protection, rail-to-rail signal handling, ±36V fault tolerance with power on, and 10Ω maximum on-resistance at ±15V supplies. It operates from dual ±4.5V to ±20V or single +9V to +36V supplies and is used in high-reliability signal routing for test equipment and industrial control systems.
For engineers reviewing the MAX313FESE+TG52 datasheet, MAX313FESE+TG52 pinout, MAX313FESE+TG52 application, or MAX313FESE+TG52 equivalent, key selection criteria include fault-protection voltage limits, on-resistance matching across channels, TTL/CMOS logic compatibility at ±15V or +12V, and SO-16 package compatibility with legacy DG412 layouts.
Technical Context
The MAX313FESE+TG52 integrates four independent NO switches, each formed by parallel N- and P-channel MOSFETs driven synchronously to achieve low RON and true bidirectional 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).
Unlike standard analog switches, it requires no power-supply sequencing: all switches remain off if V+ is unpowered-even with V− active-and all terminals retain fault protection during power-down. Logic inputs accept TTL/CMOS thresholds (+0.8V/2.4V) across its full supply range, enabling direct interface with microcontrollers and FPGAs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10 Ω max at ±15V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| RON match between channels | 0.5 Ω max at +25°C - enables matched gain/attenuation in multi-channel instrumentation and multiplexing. |
| Fault protection range | ±36V with power on, ±40V with power off - protects downstream circuitry from transient overvoltages in harsh industrial environments. |
| Fault response time | 600 ns typical - limits energy injection during fast transients, preserving integrity of sensitive measurement nodes. |
| Supply range | ±4.5V to ±20V dual or +9V to +36V single - supports wide input voltage flexibility in mixed-signal systems without external regulators. |
| Logic compatibility | TTL/CMOS thresholds (+0.8V/2.4V) at ±15V or +12V - eliminates need for external logic-level translators in embedded controller interfaces. |
| Off-isolation | −55 dB at 1 MHz - suppresses crosstalk between active and inactive channels in high-density signal routing. |
Pinout & Package
MAX313FESE+TG52 is housed in a 16-pin SOIC (SO) package with 1.27 mm pitch, JEDEC MS-012AC compliant, and rated for −40°C to +85°C operation. The package includes integrated 0.1 µF bypass capacitors recommended on V+ and GND pins per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Accept TTL/CMOS logic; drive internal gate translators to turn respective NO switches ON/OFF. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal return path for each switch; bidirectionally connected to NO terminal when enabled. |
| NO1–NO4 (Pins 3, 6, 11, 14) | Analog normally open terminals | Open-circuit when INx = 0; connect to COMx only when INx = 1 - no NC terminals present. |
| V+ (Pin 13) | Positive supply input | Bias for internal logic and P-FET gates; must be bypassed to GND with 0.1 µF capacitor. |
| V− (Pin 4) | Negative supply input | Bias for N-FET gates; connect to GND for single-supply operation. |
| GND (Pin 5) | Digital ground reference | Reference for logic inputs and internal translators; not galvanically tied to analog signal paths. |
| N.C. (Pin 12) | No connection | Not internally bonded; leave unconnected and unpopulated on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Passes analog signals from V− to V+ without clipping - essential for full-scale sensor output routing in data acquisition. |
| All-switches-off behavior | Guaranteed OFF state when V+ is unpowered - prevents unintended signal coupling during power sequencing or brownout. |
| Pin compatibility with DG412 | Identical SO-16 pinout to industry-standard non-fault-protected DG412 - enables drop-in replacement without PCB redesign. |
| 600 ns fault response | Isolates faulty channel before transient energy propagates - critical for protecting ADC front-ends and amplifier stages. |
| ±4.5V to ±20V dual supply support | Operates across asymmetric rails (e.g., +12V/−5V) up to 44V total differential - simplifies power architecture in mixed-voltage systems. |
Applications
| Test Equipment Signal Routing | Industrial Process Control I/O |

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 die, identical electrical specs and pinout; differs only in tape-and-reel packaging (TG52 denotes 2.5k reel vs. standard ESE tray). | No functional difference - interchangeable in all designs requiring SO-16 footprint and −40°C to +85°C operation. | Select MAX313FESE+TG52 for high-volume SMT assembly with automated pick-and-place feeders. |
| ADG412BRZ | Non-fault-protected quad SPST NO switch; 35 Ω RON max at ±15V; no overvoltage protection beyond ABS max ratings. | Suitable only in benign, well-regulated lab environments - cannot replace MAX313FESE+TG52 in field-deployed or safety-critical systems. | Choose ADG412BRZ only when cost is primary constraint and fault transients are absent or externally mitigated. |
Compared with MAX313FESE and ADG412BRZ, the MAX313FESE+TG52 delivers identical performance to MAX313FESE but with optimized logistics for volume production, while offering robust fault protection that ADG412BRZ lacks entirely - making it the sole choice for uncontrolled signal environments.

FAQ
What is the maximum fault voltage the MAX313FESE+TG52 can withstand with power applied?
The MAX313FESE+TG52 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. This rating applies regardless of switch state (ON or OFF) and is specified in the Absolute Maximum Ratings table of the official datasheet.
Does the MAX313FESE+TG52 require power-supply sequencing during startup?
No, the MAX313FESE+TG52 does not require power-supply sequencing. All switches remain OFF if V+ is unpowered - even when V− is active - and fault protection remains fully functional with power off. This eliminates risk of signal coupling during asymmetric power-up in complex systems.
Can the MAX313FESE+TG52 operate from a single +12V supply?
Yes, the MAX313FESE+TG52 operates from a single +12V supply by connecting V− to GND. In this configuration, it maintains ±36V fault protection, 30Ω max RON, and TTL/CMOS logic compatibility - all confirmed in the "Electrical Characteristics-Single +12V Supply" section of the datasheet.
What is the on-resistance matching specification for the MAX313FESE+TG52?
The MAX313FESE+TG52 guarantees on-resistance matching of ≤0.5Ω maximum between any two channels at +25°C with ±15V supplies. This tight matching ensures consistent gain and phase response across multiplexed signal paths in instrumentation-grade applications.
Is the MAX313FESE+TG52 pin-compatible with the DG412 analog switch?
Yes, the MAX313FESE+TG52 uses the identical SO-16 pinout as the DG412, including matching IN_, COM_, and NO_ terminal locations. This allows direct replacement in existing PCB layouts without modification - a key design advantage highlighted in the "Pin Compatibility" section of the datasheet.
