Product details
Overview
MAX314CSE+ 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 ±15V; used in audio routing, test equipment, and data acquisition systems requiring low distortion and high channel consistency.
For engineers reviewing the MAX314CSE+ datasheet, MAX314CSE+ pinout, MAX314CSE+ application, or MAX314CSE+ equivalent, key selection criteria include verified dual-supply operation (±4.5V to ±20V), guaranteed break-before-make timing (70ns typ), crosstalk >96dB at 20kHz, and TSSOP-16 package compatibility with legacy DG41x footprints.
Technical Context
The MAX314CSE+ implements a fully complementary CMOS transmission-gate architecture enabling bidirectional conduction, rail-to-rail analog signal switching, and logic-level control via independent IN1–IN4 inputs. Its internal charge-pump–assisted gate drive ensures stable RON flatness (≤2Ω) across ±10V signal ranges.
Unlike MAX312 (NC-only) and MAX313 (NO-only), the MAX314CSE+ integrates mixed NO/NC topology per package-switches 1 & 4 are NC, switches 2 & 3 are NO-enabling simultaneous signal path enablement and bypass in sample-and-hold or redundancy circuits without external logic inversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 6.5Ω typical, ≤10Ω max at VCOM = ±10V - ensures minimal signal attenuation and THD degradation in audio paths. |
| RON Matching | ≤1.5Ω max between any two channels - critical for matched gain/phase in differential or multi-channel routing. |
| Supply Range | +4.5V to +30V single supply or ±4.5V to ±20V dual supply - supports industrial ±15V rails and battery-powered 5V/12V systems. |
| Break-Before-Make Delay | 70ns typical (MAX314 only) - prevents momentary shorting during channel switching in multiplexed sensor interfaces. |
| Crosstalk | >96dB at 20kHz - maintains channel isolation in high-fidelity audio and communication signal routing. |
| Charge Injection | ±30pC max - limits voltage glitch on high-impedance nodes like sample-and-hold capacitors. |
| ESD Protection | >2000V per Method 3015.7 - enables robust handling in automated test and field-deployable equipment. |
Pinout & Package
MAX314CSE+ is housed in a 16-pin narrow SOIC (SO) package (3.9mm width), pin-compatible with industry-standard DG411/DG412/DG413 and functionally identical to MAX314CPE in pin assignment and thermal profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Independent TTL/CMOS logic inputs controlling each SPST switch; active-high for NO channels, active-low for NC channels. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal ports connected to load/sensor side of each switch. |
| 3, 6, 11, 14 | NC1–NC4 / NO1–NO4 | MAX314-specific: Pins 3 & 6 = NC2 & NC1; Pins 11 & 14 = NO3 & NO4 - defines mixed NO/NC topology per device. |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation (0V to +30V). |
| 5 | GND | Logic ground reference; separate from analog return to minimize noise coupling. |
| 12 | V+ | Positive analog supply rail - sets upper limit of rail-to-rail signal swing. |
| 13 | VL | Logic supply input - accepts 2.7V to V+ (with V+ ≤ 30V), enabling level-shifted control from 3.3V or 5V microcontrollers. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC topology | Two NC (switches 1 & 4) and two NO (switches 2 & 3) in one IC - eliminates need for external inverters in fail-safe or redundant signal path designs. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±10V instrumentation and audio line-level routing. |
| Guaranteed RON flatness | ≤2Ω variation over full ±10V signal range - preserves amplitude accuracy in precision measurement front-ends. |
| Low leakage at temperature | ≤2.5nA off-leakage at +85°C - maintains integrity in high-impedance sensor multiplexing and long-hold sample-and-hold circuits. |
| Pin compatibility with DG41x | Direct PCB replacement for DG411/DG412/DG413 - reduces redesign effort when upgrading to lower RON and improved ESD performance. |
Applications
| Audio Signal Routing | Test Equipment Multiplexing |
|---|---|
|
Use Scenario: Switching line-level stereo signals between multiple sources (CD, DAC, phono preamp) in professional audio mixers. IC Role / Device Role / Timing Role: Quad SPST analog switch providing isolated, low-distortion signal paths with simultaneous NO/NC control for mute/bypass functions. Use Value: 6.5Ω RON and >96dB crosstalk prevent inter-channel bleed and preserve THD below 0.001% at 1kHz. |
Use Scenario: Routing DUT signals to multiple measurement instruments (oscilloscope, spectrum analyzer, DMM) in automated test systems. IC Role / Device Role / Timing Role: High-voltage-tolerant analog switch enabling ±15V signal switching under microcontroller control with break-before-make timing. Use Value: ±20V dual-supply support and 70ns break-before-make delay prevent transient shorts during instrument reconfiguration. |
| Data Acquisition Channel Selection | Avionics Signal Conditioning |
|
Use Scenario: Selecting among 4 pressure, temperature, or strain sensor outputs feeding a shared ADC in industrial PLC modules. IC Role / Device Role / Timing Role: Low-leakage (2.5nA @ +85°C), matched RON (≤1.5Ω) quad switch ensuring consistent gain and offset across channels. Use Value: Matched on-resistance minimizes channel-to-channel gain error; low leakage avoids drift in high-Z sensor bridges. |
Use Scenario: Isolating and routing analog sensor data (e.g., airspeed, altitude) between redundant flight control units in certified avionics hardware. IC Role / Device Role / Timing Role: Dual-redundant SPST switch implementing fail-safe NC/NO pairing for automatic fallback path activation. Use Value: Mixed NC/NO configuration enables self-checking signal paths; >2000V ESD rating meets DO-160 Section 22 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313CSE+ | Quad NO-only SPST; identical RON, supply range, and package - lacks NC functionality. | Suitable where all four paths require active-high enable without passive continuity. | Select MAX313CSE+ only if NC behavior is unnecessary; MAX314CSE+ provides greater topology flexibility. |
| ADG413BRZ | Quad SPST, NO-only; 35Ω RON (typ), ±15V supply, SOIC-16 - higher on-resistance, no NC option. | Better suited for low-speed, low-precision switching where power efficiency outweighs signal fidelity. | Choose ADG413BRZ for cost-sensitive, non-critical routing; MAX314CSE+ preferred for low-distortion, matched-path designs. |
Compared with MAX313CSE+ (NO-only) and ADG413BRZ (higher RON, NO-only), the MAX314CSE+ uniquely delivers mixed NO/NC topology with sub-10Ω RON and guaranteed matching - enabling fail-safe signal routing and precision multiplexing unattainable with either alternative.

FAQ
What is the operating temperature range for MAX314CSE+?
The MAX314CSE+ is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its C-grade ordering suffix and suits benchtop test gear, audio interfaces, and non-mission-critical industrial controls. For extended-range alternatives, consider MAX314ESE+ (–40°C to +85°C) or MAX314MJE (–55°C to +125°C).
Does MAX314CSE+ support single-supply operation?
Yes, MAX314CSE+ operates from a single supply of +4.5V to +30V. In this mode, connect V− to GND and apply the positive rail to V+. The device maintains rail-to-rail analog signal handling (0V to V+) and retains all key specs including ≤10Ω RON and ≤2.5nA leakage at +85°C - confirmed in the Single-Supply Electrical Characteristics table.
How does the mixed NO/NC configuration of MAX314CSE+ work?
In MAX314CSE+, switches 1 and 4 are normally closed (NC), while switches 2 and 3 are normally open (NO). When IN1 or IN4 is logic low, their respective NC switches conduct; when IN2 or IN3 is logic high, their NO switches conduct. This allows simultaneous use of fail-safe (NC) and active-enable (NO) paths - e.g., default signal pass-through with optional override routing - without external logic.
Is MAX314CSE+ pin-compatible with DG411/DG412/DG413?
Yes, MAX314CSE+ is pin-compatible with DG411 (quad NO), DG412 (quad NC), and DG413 (dual NO/dual NC) in SOIC-16 packages. Pin assignments for COM, NO/NC, IN, V+, V−, GND, and VL match exactly - enabling drop-in replacement with improved RON, tighter matching, and enhanced ESD protection (>2000V vs. ~2kV).
What is the maximum analog signal voltage supported by MAX314CSE+?
MAX314CSE+ supports analog signals from V− to V+, with absolute maximum ratings of –44V to +44V on V+ and V−. Under normal operation, the analog signal range is limited by the supply rails: ±4.5V to ±20V for dual supplies or 0V to +30V for single supply. At ±15V supplies, it reliably handles ±10V signals with ≤2Ω RON flatness - verified in Figure 2 of the datasheet.
