Product details
Overview
MAX314EUE 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, 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail signal handling up to ±20V dual supply or +30V single supply - used in precision audio routing and data acquisition front-ends.
For engineers reviewing the MAX314EUE datasheet, MAX314EUE pinout, MAX314EUE application, or MAX314EUE equivalent, key selection criteria include verified NC/NO channel pairing, guaranteed RON flatness ≤2Ω over ±10V signal range, crosstalk >96dB at 20kHz, and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The MAX314EUE implements a complementary MOSFET architecture enabling bidirectional conduction and rail-to-rail analog signal switching across its four independent SPST switches. Its logic inputs accept TTL/CMOS-compatible levels referenced to VL (2.4V high, 0.8V low), with separate V+ and V− supplies supporting bipolar operation.
Each channel features matched on-resistance (ΔRON ≤1.5Ω), flat on-resistance (≤2Ω variation over full signal range), and low charge injection (±30pC typical), ensuring minimal signal distortion in sample-and-hold and low-noise audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 6.5Ω typical, ≤10Ω max at 10mA - ensures minimal voltage drop and gain error in precision signal paths |
| RON match between channels | ≤1.5Ω max - enables accurate differential or multi-channel signal routing without channel-to-channel gain mismatch |
| Analog signal range | ±10V with ±15V supplies or 0V to +12V with single +12V supply - supports rail-to-rail input/output in industrial and test equipment |
| Crosstalk | >96dB at 20kHz - prevents audible interference in stereo audio routing and sensitive measurement systems |
| Charge injection | ±30pC max - limits voltage glitch in sample-and-hold circuits and ADC front-ends |
| Off isolation | −65dB at 1MHz - suppresses leakage from active to inactive channels in multiplexed signal chains |
| ESD tolerance | >2000V per Method 3015.7 - enhances robustness during board assembly and field handling |
Pinout & Package
MAX314EUE is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch), optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Active-high TTL/CMOS-compatible signals controlling NO/NC state of respective switches |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal path junctions connecting to NO or NC outputs based on logic state |
| NO1, NO4 (Pins 3, 6); NO2, NO3 (Pins 11, 14) | Normally open analog outputs | Connected to COMx only when corresponding INx = logic high - used for default-open signal gating |
| NC1, NC4 (Pins 11, 14); NC2, NC3 (Pins 3, 6) | Normally closed analog outputs | Connected to COMx when corresponding INx = logic low - provides fail-safe continuity in power-loss scenarios |
| V+ (Pin 13), V− (Pin 4) | Analog supply rails | Support ±4.5V to ±20V dual supply or +4.5V to +30V single supply (V− tied to GND) |
| VL (Pin 12) | Logic supply reference | Accepts 2.0V to V+ − 1.0V; sets logic threshold and reduces switching noise coupling into analog paths |
| GND (Pin 5) | Logic ground | Reference for VL and digital inputs; isolated from analog ground in mixed-signal layouts |
Key Features
| Feature | Design Value |
|---|---|
| Two NC + two NO configuration | Enables simultaneous fail-safe and active-gated signal routing in safety-critical or redundant systems |
| RON flatness ≤2Ω | Maintains consistent gain and linearity across full ±10V analog input range - critical for instrumentation amplifiers |
| Break-before-make timing | 70ns typical delay (MAX314 only) - prevents momentary shorting in relay-replacement applications |
| Rail-to-rail signal handling | Supports input signals from V− to V+ without clipping - essential for ±10V industrial sensor interfaces |
| Low THD at audio frequencies | <−80dB at 1kHz (600Ω source/load) - meets professional audio routing requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG441BRUZ | Quad SPST, 45Ω RON, single +3V to +16V supply only, no NC/NO split | Limited to low-voltage, low-power portable instruments; lacks bipolar support and NC/NO flexibility | Select when ultra-low quiescent current (<1nA) and 3V operation are mandatory, and ±10V signal handling is unnecessary |
| TS5A23157DGSR | Quad SPDT (not SPST), 0.9Ω RON, +1.65V to +5.5V supply, no dual-supply capability | Requires redesign for SPDT logic and cannot replace MAX314EUE's NC/NO functional partitioning | Choose only for cost-sensitive, single-supply consumer audio where SPDT topology aligns with system architecture |
Compared with ADG441BRUZ and TS5A23157DGSR, the MAX314EUE uniquely delivers split NC/NO functionality, ±20V dual-supply operation, and sub-10Ω RON within a pin-compatible TSSOP-16 footprint - making it irreplaceable in high-fidelity, high-voltage, and safety-aware analog routing.

FAQ
What is the operating temperature range for MAX314EUE?
The MAX314EUE is rated for −40°C to +85°C operation, validated across all electrical specifications including RON, leakage, and switching times. This extended industrial temperature grade ensures reliable performance in harsh environments such as factory automation controllers and outdoor test equipment enclosures where ambient temperatures exceed commercial-grade limits.
Does MAX314EUE support dual-supply operation?
Yes, MAX314EUE supports dual-supply operation from ±4.5V to ±20V, enabling true bipolar signal handling. When configured this way, the analog signal range extends from V− to V+, allowing seamless interfacing with ±10V industrial sensors and legacy instrumentation without level-shifting circuitry - a capability confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables.
How does the NC/NO channel arrangement work in MAX314EUE?
In MAX314EUE, Pins 1 and 4 control NC1/NC4 (normally closed), while Pins 2 and 3 control NO2/NO3 (normally open). When IN1 = low, COM1 connects to NC1; when IN1 = high, COM1 disconnects. Conversely, NO2 connects to COM2 only when IN2 = high. This dual-mode topology allows one pair to maintain default continuity and another to enable controlled signal insertion - verified in the truth table and pin description sections.
Is MAX314EUE pin-compatible with DG411/DG412/DG413?
Yes, MAX314EUE is pin-compatible with DG411 (quad SPST NO), DG412 (quad SPST NC), and DG413 (dual SPST NO + dual SPST NC) in 16-pin packages. The pin mapping for COM, NO, NC, IN, V+, V−, VL, and GND matches functionally - confirmed in the "Pin Compatible with DG411/DG412/DG413" feature bullet and top-view diagrams for all three MAX devices.
What is the maximum analog signal voltage MAX314EUE can handle?
MAX314EUE supports analog signals from V− to V+, with absolute maximum ratings of −44V to +44V on V+ and V−. Under recommended operating conditions, it reliably handles ±10V signals with ±15V supplies or 0V to +12V with +12V single supply - explicitly specified in the Analog Signal Range parameter (VCOM_, VNO_, VNC_) across both dual- and single-supply electrical characteristics tables.
