Product details
Overview
MAX314EPE from Maxim Integrated is a quad, single-pole/single-throw (SPST) CMOS analog switch with two normally closed (NC) and two normally open (NO) channels. It features 10Ω maximum on-resistance, 1.5Ω maximum on-resistance matching between channels, rail-to-rail signal handling, and operates from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply. It is used in audio signal routing and data acquisition systems requiring low distortion and precise channel switching.
For engineers reviewing the MAX314EPE datasheet, MAX314EPE pinout, MAX314EPE application, or MAX314EPE equivalent, key selection criteria include verified NC/NO channel configuration, guaranteed RON flatness (≤2Ω), ESD tolerance >2000V per Method 3015.7, crosstalk >96dB at 20kHz, and compatibility with DG411/DG412/DG413 pinouts for drop-in replacement in legacy designs.
Technical Context
The MAX314EPE implements four independent SPST switches in a single monolithic CMOS structure, with dedicated control inputs (IN1–IN4) enabling individual channel activation. Its internal architecture ensures symmetrical conduction-identical performance regardless of signal direction-and guarantees ≤1.5Ω RON mismatch across all four channels under full temperature range (−40°C to +85°C).
It supports rail-to-rail analog signal ranges up to ±15V with dual supplies or 0V to +12V with single supply, and integrates logic-level translation via VL pin (2.4V–5.5V compatible). Break-before-make timing is specified at 70ns (typ) for the MAX314 variant, preventing momentary shorting during channel transitions in mixed-signal routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10Ω max - ensures minimal voltage drop and power loss in precision signal paths |
| RON match between channels | 1.5Ω max - enables matched gain/attenuation in differential or multi-channel instrumentation |
| Analog signal range | ±15V (dual) or 0V to +12V (single) - supports full-rail operation without clipping in industrial sensor interfaces |
| Crosstalk | >96dB at 20kHz - critical for high-fidelity audio routing where inter-channel bleed must be suppressed |
| ESD protection | >2000V per Method 3015.7 - provides robust handling during board assembly and field service |
| Turn-on/turn-off time | 225ns / 175ns (max at TA = +85°C) - suitable for medium-speed multiplexing in automated test equipment |
| Off leakage current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor front-ends |
Pinout & Package
MAX314EPE is supplied in a 16-pin plastic DIP package (0.300" wide), RoHS-compliant and rated for −40°C to +85°C operation. Pin spacing conforms to standard 0.1" grid; body dimensions are 0.337" × 0.197" × 0.150".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 | Logic control inputs | Active-high digital signals controlling respective switch states (IN1/IN4 → NO1/NO4; IN2/IN3 → NC2/NC3) |
| COM1–COM4 | Analog common terminals | Signal input/output nodes shared between NC and NO paths per channel |
| NO1, NO4 | Normally open analog terminals | Connected to COMx only when corresponding INx = logic high |
| NC2, NC3 | Normally closed analog terminals | Connected to COMx when corresponding INx = logic low; disconnected when INx = high |
| V+, V− | Analog supply rails | Support bipolar (±4.5V to ±20V) or single-supply (V− = GND) configurations |
| VL | Logic supply reference | Accepts 2.4V–5.5V to interface with TTL/CMOS logic; decouples logic from analog supply noise |
| GND | Logic ground | Reference for VL and digital inputs; separate from analog return path in mixed-signal layouts |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: MAX314EPE acts as a programmable analog multiplexer, routing ±15V calibration signals while maintaining <1.5Ω channel matching. Use Value: Guaranteed RON flatness and low leakage ensure measurement repeatability across temperature and signal amplitude. | Use Scenario: Professional audio mixers route line-level stereo signals between processing stages without audible artifacts. IC Role / Device Role / Timing Role: MAX314EPE serves as a low-distortion analog switch matrix, leveraging its 96dB crosstalk and rail-to-rail capability. Use Value: THD below −100dB at 1kHz enables transparent signal path switching in broadcast-grade audio infrastructure. |
| Data Acquisition Systems | Avionics Signal Conditioning |
Use Scenario: Industrial DAQ modules condition and multiplex high-impedance sensor outputs (e.g., thermocouples, strain gauges) before ADC sampling. IC Role / Device Role / Timing Role: MAX314EPE functions as a low-leakage analog front-end switch, isolating unused channels to prevent loading. Use Value: 2.5nA max off-leakage at +85°C preserves signal integrity in high-Z sensor interfaces over extended operating temperatures. | Use Scenario: Aircraft flight control systems route redundant analog sensor signals (e.g., airspeed, altitude) with fail-safe redundancy management.

Use Value: Two NC + two NO topology enables hardware-level redundancy switching without external logic or relays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314CPE | Same functionality and pinout; rated for 0°C to +70°C commercial temperature range | Suitable for non-industrial environments where extended temperature operation is not required | Select MAX314CPE for cost-sensitive consumer or lab equipment with ambient thermal constraints |
| ADG414BRZ | Quad SPST, 12Ω RON, −40°C to +85°C, but no integrated NC/NO pairing - all four channels are NO-only | Requires external logic to emulate NC behavior; lacks native break-before-make capability of MAX314EPE | Choose ADG414BRZ only when NC function is unnecessary and footprint compatibility with SOIC-16 is prioritized |
Compared with MAX314CPE, the MAX314EPE offers extended temperature reliability for industrial deployment; versus ADG414BRZ, it delivers native NC/NO channel pairing-eliminating external components and PCB area in redundancy-critical avionics and test systems.

FAQ
What is the operating temperature range of the MAX314EPE?
The MAX314EPE is rated for operation from −40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. The 'E' suffix explicitly denotes this grade, distinguishing it from the 'C' (0°C to +70°C) and 'M' (−55°C to +125°C) variants. Thermal performance parameters-including RON, leakage, and switching times-are fully characterized across this range.
Does the MAX314EPE support single-supply operation?
Yes, the MAX314EPE supports single-supply operation from +4.5V to +30V, with V− connected to GND. Electrical Characteristics tables explicitly list performance data under single-supply conditions (e.g., V+ = 12V, V− = 0V). The device maintains rail-to-rail signal handling and retains all key specs-including 10Ω max RON and 2.5nA max off-leakage at +85°C-under this configuration.
How does the NC/NO channel configuration work in the MAX314EPE?
The MAX314EPE integrates two normally closed (NC2, NC3) and two normally open (NO1, NO4) switches. When IN2 or IN3 is logic low, the corresponding NC switch conducts; when high, it opens. Conversely, NO1 and NO4 conduct only when IN1 or IN4 is high. This is confirmed in the Functional Diagram and Pin Description sections, which assign IN1/IN4 to NO control and IN2/IN3 to NC control-enabling independent, mixed-mode switching in one package.
Is the MAX314EPE pin-compatible with the DG411 series?
Yes, the MAX314EPE is pin-compatible with DG411, DG412, and DG413 as stated in the Features section. All share identical 16-pin DIP/SO/TSSOP pinouts, including matching assignments for COM, NO, NC, IN, V+, V−, VL, and GND. This allows direct physical replacement in legacy designs without PCB modification-provided voltage and timing requirements align with the MAX314EPE's specifications.
What is the maximum analog signal voltage the MAX314EPE can handle?
The MAX314EPE supports analog signal voltages from V− to V+, with absolute maximum ratings of −44V to +44V referenced to GND. Under normal operation, the specified analog signal range is ±15V with dual supplies (V+ = +15V, V− = −15V) or 0V to +12V with single supply (V+ = +12V, V− = 0V). These limits are validated in the Electrical Characteristics tables and Typical Operating Characteristics plots.
