Product details
Overview
MAX314CSE+T 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 across ±4.5V to ±20V dual supplies or +4.5V to +30V single supply. It is used in precision audio routing and data acquisition systems requiring low distortion and tight channel matching.
For engineers reviewing the MAX314CSE+T datasheet, MAX314CSE+T pinout, MAX314CSE+T application, or MAX314CSE+T equivalent, key selection criteria include verified on-resistance flatness (≤2Ω), guaranteed ESD protection (>2000V per Method 3015.7), crosstalk performance (>96dB at 20kHz), and break-before-make timing (70ns typical) specific to its dual-NC/dual-NO configuration.
Technical Context
The MAX314CSE+T implements a fully complementary CMOS SPST architecture with independent logic control of four switches-IN1/IN2 drive NC1/NC2 (normally closed), while IN3/IN4 drive NO3/NO4 (normally open). Its internal charge-pump–assisted level-shifting enables rail-to-rail analog conduction without signal clipping across the full ±20V or +30V supply range.
It guarantees monotonic on-resistance flatness (≤2Ω over ±10V signal range) and matched RON (≤1.5Ω delta between any two channels), enabling high-fidelity multiplexing in sample-and-hold and test equipment where gain/phase tracking errors must remain below 0.01%. Leakage is specified at ±2.5nA at +85°C for both on and off states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 6.5Ω typical, ≤10Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Matching | ≤1.5Ω max between channels - enables accurate differential or ratiometric measurements without calibration |
| RON Flatness | ≤2Ω max over ±10V signal range - preserves linearity and THD < −80dB in audio and instrumentation |
| Crosstalk | >96dB at 20kHz - prevents inter-channel interference in multi-signal routing applications |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +30V single - supports industrial bipolar and automotive single-rail systems |
| ESD Protection | >2000V per Method 3015.7 - eliminates need for external transient suppression in board-level ESD zones |
| Charge Injection | ±30pC max - limits voltage glitch on high-impedance nodes in sample-and-hold and ADC front-ends |

| Break-before-make timing | 70ns typical (MAX314 only) - prevents momentary shorting in dual-NC/dual-NO configurations during state transitions |
| Low off-leakage | ±2.5nA max at +85°C - maintains accuracy in high-impedance sample-and-hold and medical front-ends |
| Pin compatibility | Direct replacement for DG411/DG412/DG413 - enables drop-in upgrade to lower RON and improved matching |
| THD performance | −100dB at 1kHz (5Vrms, 600Ω) - meets Class A audio and precision measurement requirements |
Applications
| Audio Signal Routing | Test Equipment Multiplexing |
|---|---|
|
Use Scenario: Switching line-level stereo signals between multiple amplifiers and codecs in professional audio mixers. IC Role / Device Role / Timing Role: Quad SPST analog switch providing isolated, low-distortion signal paths with simultaneous NC/NO control for mute/unmute and source selection. Use Value: 6.5Ω RON and <−100dB THD preserve dynamic range; 96dB crosstalk prevents left/right channel bleed at 20kHz. |
Use Scenario: Routing DUT signals to multiple measurement instruments (oscilloscope, spectrum analyzer, DMM) in automated test systems. IC Role / Device Role / Timing Role: Precision analog multiplexer enabling sequential channel access with guaranteed RON matching ≤1.5Ω for calibrated gain consistency. Use Value: ≤2Ω RON flatness ensures amplitude accuracy across ±10V input range; low leakage (<2.5nA) avoids drift in high-Z probe circuits. |
| Data Acquisition Front-End | Avionics Signal Conditioning |
|
Use Scenario: Selecting among multiple sensor outputs (thermocouple, RTD, strain gauge) prior to PGA and ADC in industrial DAQ modules. IC Role / Device Role / Timing Role: Low-leakage, rail-to-rail analog switch isolating high-impedance sensors from shared signal chain while maintaining offset stability. Use Value: ±2.5nA off-leakage at +85°C minimizes input bias error; 30pC charge injection prevents hold-step errors in SAR ADC sampling. |
Use Scenario: Managing redundant analog sensor feeds (airspeed, altitude, attitude) in flight control computers with fail-safe switching. IC Role / Device Role / Timing Role: Dual-NC/dual-NO configuration enables hot-swap redundancy - NC paths maintain default signal flow until NO paths are activated for switchover. Use Value: Break-before-make delay (70ns) prevents transients during reconfiguration; >2000V ESD rating meets DO-160 Section 22 Level 3 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+T | Quad NO-only configuration (vs. MAX314's dual-NC/dual-NO); identical RON, matching, and supply specs | Suitable for designs requiring all channels to be open-circuit by default - no default signal path | Select when system safety or power-on default requires open-circuit behavior across all channels |
| ADG441BRZ | Quad NO, 45Ω RON (typ), ±15V supply max, no break-before-make spec, 16-pin SOIC | Limited to lower-voltage industrial systems; higher RON increases insertion loss and self-heating | Choose only if supply range ≤±15V suffices and RON tolerance >40Ω is acceptable for signal integrity |
Compared with MAX313CSE+T and ADG441BRZ, the MAX314CSE+T uniquely provides mixed NC/NO topology with verified 70ns break-before-make timing and superior RON flatness (≤2Ω), making it irreplaceable in fault-tolerant avionics and precision audio routing where default path integrity and signal fidelity are non-negotiable.

FAQ
What is the maximum allowable analog signal range for MAX314CSE+T when operated from ±15V supplies?
The MAX314CSE+T supports an analog signal range from V− to V+, i.e., −15V to +15V, with rail-to-rail conduction. This is confirmed in the Absolute Maximum Ratings table (VCOM_, VNO_, VNC_ = V− to V+) and Electrical Characteristics (Analog Signal Range = ±10V min, up to full rail). Operation beyond ±15V violates absolute max ratings and risks permanent damage.
Does MAX314CSE+T require external pull-up or pull-down resistors on its logic inputs (IN1–IN4)?
No. The MAX314CSE+T logic inputs are CMOS-compatible with guaranteed thresholds (VINH = 2.4V, VINL = 0.8V) and input currents ≤±0.5µA at +25°C. External resistors are unnecessary unless interfacing with open-drain or high-impedance sources; the device drives cleanly from standard 3.3V or 5V logic without loading.
Can MAX314CSE+T be used in single-supply +12V systems with ground-referenced analog signals?
Yes. Configure V− = GND, V+ = +12V, and VL = +3.3V or +5V. The analog signal range becomes 0V to +12V, and all specifications - including RON (12.5Ω typ), leakage (±2.5nA), and switching times - are validated per the Single-Supply Electrical Characteristics table. Ground isolation between GND and analog return is recommended.
What is the thermal resistance (θJA) of the MAX314CSE+T in its narrow SOIC package?
The MAX314CSE+T in 16-pin narrow SOIC has a junction-to-ambient thermal resistance (θJA) of 8.70°C/W, as stated in the Absolute Maximum Ratings section under "Continuous Power Dissipation (TA = +70°C): Narrow SO (derate 8.70mW/°C above +70°C)". This value assumes standard JEDEC 2-layer board conditions.
Is MAX314CSE+T pin-compatible with the industry-standard DG411 analog switch?
Yes. The MAX314CSE+T is explicitly advertised as pin-compatible with DG411/DG412/DG413 per the Features section. Pin assignments (IN, COM, NO/NC, V+, V−, GND, VL) match identically in the 16-pin SOIC footprint, enabling direct PCB replacement without layout changes - provided supply voltages and logic levels fall within compatible ranges.
