Product details
Overview
MAX314FESE+ from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, fault-protected to ±36V with power on and ±40V with power off, 10Ω max on-resistance at ±15V, rail-to-rail signal handling, and TTL/CMOS-compatible logic inputs - used in industrial process control signal routing where overvoltage transients and hot-swap reliability are critical.
For engineers reviewing the MAX314FESE+ datasheet, MAX314FESE+ pinout, MAX314FESE+ application, or MAX314FESE+ equivalent, this page delivers verified electrical specs, fault-response timing, package-validated pin functions, and real-world substitution guidance for high-reliability analog switching in avionics, ATE, and redundant systems.
Technical Context
The MAX314FESE+ implements dual-FET parallel architecture per channel (N- and P-channel MOSFETs driven in phase), enabling low RON and true bidirectional rail-to-rail conduction. Its dual-comparator fault-detection circuitry monitors COM_, NO_, and NC_ terminals independently against V+ and V−, forcing high-impedance isolation within 600ns (typ) during overvoltage events.
It operates across ±4.5V to ±20V dual supplies or +9V to +36V single supply (V− = GND), with logic thresholds fixed at +0.8V (VIL) and +2.4V (VIH). All four switches power down to OFF state when V+ is unpowered - even if V− remains active - ensuring fail-safe signal blocking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10 Ω (max) at ±15V - ensures minimal voltage drop and signal attenuation in precision analog paths. |
| Fault Protection Range | ±36V with power on, ±40V with power off - protects downstream circuitry from transient overvoltages without external clamping. |
| Fault Response Time | 600 ns (typ) - limits energy injection during fast transients, preserving integrity of connected sensors or DACs. |
| Supply Range | ±4.5V to ±20V dual or +9V to +36V single - supports legacy ±15V industrial rails and modern high-voltage single-supply test equipment. |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V) - interfaces directly with microcontrollers and FPGAs without level-shifting. |
| Break-Before-Make Delay | 2 ns (typ) for MAX314F only - prevents momentary shorting during channel switching in mixed NO/NC configurations. |
| Off-Isolation | −55 dB at 1 MHz - suppresses crosstalk between active and inactive channels in dense multiplexed systems. |
Pinout & Package
MAX314FESE+ is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible, with 1.27 mm pitch and JEDEC MS-012AC standard dimensions. Thermal performance supports continuous operation at +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Active-high logic signals enabling/disabling respective switches; compatible with 3V/5V/12V logic families. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Bidirectional signal path hubs - connect to system reference point (e.g., ADC input, sensor output). |
| NO1, NO4 (Pins 3, 6) | Normally open analog outputs | Connect to COMx only when corresponding INx = HIGH; used for selective signal activation. |
| NC2, NC3 (Pins 11, 14) | Normally closed analog outputs | Connected to COMx when INx = LOW; provide default signal path for fail-safe or standby modes. |
| V+ (Pin 13) | Positive supply rail | Must be bypassed with 0.1 µF capacitor to GND; sets upper fault threshold and logic translator bias. |
| V− (Pin 4) | Negative supply rail | Connect to GND for single-supply use; defines lower fault threshold and enables rail-to-rail swing. |
| GND (Pin 5) | Digital ground reference | Return path for logic circuitry only - no galvanic connection to analog signal paths. |
| N.C. (Pin 12) | No connection | Internally unconnected; must remain floating - not tied to any potential. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor or DAC interfacing. |
| Pin compatibility with DG411/DG412/DG413 | Drop-in replacement for legacy non-fault-protected switches - eliminates PCB redesign in field upgrades. |
| No power-supply sequencing required | V+ and V− may be powered in any order - simplifies power management in multi-rail systems. |
| All switches OFF with power removed | Guaranteed high-impedance state during brownout or hot-swap - prevents backfeeding or signal leakage. |
| 600 ns typical fault response time | Fast isolation limits fault energy transfer - critical for protecting sensitive measurement front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314CESE+ | Lacks fault protection; RON = 35 Ω (max) at +12V; no ±40V power-off protection. | Suitable only in benign, low-voltage environments with external protection. | Select only when cost sensitivity outweighs reliability requirements and transients are fully suppressed upstream. |
| ADG1414BRUZ | 4-channel, 2 NO/2 NC, but fault protection limited to ±20V; RON = 1.8 Ω (typ); requires external fault logic. | Higher bandwidth (170 MHz) but lower fault margin - appropriate for RF test, not industrial surge zones. | Prefer for high-speed, low-RON needs where ±36V fault tolerance is not mandated by system spec. |
Compared with MAX314CESE+, MAX314FESE+ adds robust ±36V fault protection and rail-to-rail operation at modest RON cost; versus ADG1414BRUZ, it trades bandwidth for superior fault resilience and simpler integration in harsh environments.

FAQ
What is the maximum fault voltage the MAX314FESE+ can withstand with power applied?
The MAX314FESE+ sustains overvoltage faults up to ±36V on COM_, NO_, or NC_ terminals when power is applied - verified across its full operating temperature range (−40°C to +85°C) and compatible with ±15V dual supplies or +12V single supply. This rating applies regardless of switch state (ON or OFF) and is defined in the Absolute Maximum Ratings table of the official datasheet.
Does the MAX314FESE+ require power-supply sequencing during startup?
No, the MAX314FESE+ does not require power-supply sequencing. Its internal logic and fault-protection circuitry operate correctly whether V+ powers up before V−, after V−, or simultaneously - a key advantage in complex multi-rail systems. This behavior is explicitly confirmed in the "No Power-Supply Sequencing Required" feature list and validated in the Detailed Description section of the datasheet.
How does the MAX314FESE+ behave when V+ is unpowered but V− remains active?
When V+ is unpowered (0V), the MAX314FESE+ forces all four switches into the OFF state - regardless of V− voltage or logic input states. This fail-safe behavior is guaranteed and documented in both the Features list ("All Switches Off when V+ is Off and V− is On") and the Detailed Description section, ensuring signal isolation during partial power loss scenarios.
What is the on-resistance matching between channels for the MAX314FESE+?
The MAX314FESE+ guarantees on-resistance matching of ≤0.5 Ω (max) between any two channels at +25°C under ±15V supplies - measured as ∆RON = RON(MAX) − RON(MIN). This tight matching ensures consistent gain and offset across multiplexed channels in precision instrumentation applications, as specified in the Electrical Characteristics table.
Can the MAX314FESE+ be used with a single +24V supply?
Yes, the MAX314FESE+ supports single-supply operation from +9V to +36V. With V− connected to GND and V+ = +24V, it maintains rail-to-rail signal handling (0V to +24V), 30 Ω max RON, and ±36V fault protection - all confirmed in the "ELECTRICAL CHARACTERISTICS-Single +12V Supply" section and extended by characterization curves up to +36V in the Typical Operating Characteristics.
