Product details
Overview
MAX314LCUE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, 10Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V). It enables precision signal routing in audio multiplexing and data-acquisition front-ends where rail-to-rail signal handling and low channel mismatch are critical.
For engineers reviewing the MAX314LCUE+ datasheet, MAX314LCUE+ pinout, MAX314LCUE+ application, or MAX314LCUE+ equivalent, this page delivers verified electrical specs, package mapping to 16-pin TSSOP, confirmed pin functions per MAX314L topology, real-world leakage and timing performance at temperature extremes, and validated alternative options for SPST analog switching in industrial and test equipment designs.
Technical Context
The MAX314LCUE+ implements four independent CMOS SPST switches in a single die, with dedicated NC and NO terminals per channel-switches 1 and 4 are NC, switches 2 and 3 are NO-enabling mixed-mode signal path control without external reconfiguration. Its logic interface accepts +3V-tolerant inputs across full supply ranges, eliminating level-shifting circuitry.
Internally, it uses matched transistor pairs to guarantee ≤1.5Ω on-resistance matching between channels and ≤2Ω on-resistance flatness over ±10V signal swing under dual supplies. Break-before-make timing is specified at 1ns to 10ns (typical 5ns), preventing transient short-circuits during channel transitions in sensitive analog paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths up to ±10V. |
| RON match between channels | 1.5Ω max - maintains amplitude consistency across multiplexed channels in instrumentation and audio routing. |
| Analog signal range | ±15V (dual) or 0–+12V (single) - supports rail-to-rail signal handling without clipping in wide-dynamic-range systems. |
| Off-leakage current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces. |
| Turn-on/turn-off time | 115–275ns (tON), 100–235ns (tOFF) - enables fast switching in automated test equipment and digital potentiometer replacement. |
| Crosstalk | >96dB at 20kHz - isolates adjacent audio or measurement channels to prevent audible artifacts or measurement crosstalk. |
| Logic compatibility | +3V input thresholds (VIH = 2.0V, VIL = 0.8V) - interoperates directly with FPGA, MCU, and CPLD GPIO without pull-ups or translators. |
Pinout & Package
MAX314LCUE+ is housed in a 16-pin Thin Shrink Small Outline Package (TSSOP), 4.4mm × 5.0mm body, 0.65mm pitch, with exposed pad connected to V+ for thermal enhancement and noise reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Digital enable signals for each SPST switch; active-high, +3V compatible, drive internal gate drivers. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal input/output nodes shared between NC and NO paths; bidirectional conduction with matched RON. |
| NC1, NC2 (Pins 11, 14) | Normally closed analog terminals | Connected to COMx when INx = 0; used for default-path routing or fail-safe signal continuity. |
| NO1, NO4 (Pins 3, 6) | Normally open analog terminals | Connected to COMx when INx = 1; enables on-demand signal insertion or bypass in programmable gain stages. |
| V+ (Pin 13) | Positive analog supply | Bias for internal CMOS switches; must be ≥+4.5V (single) or ≤+20V (dual); connects to exposed pad. |
| V− (Pin 4) | Negative analog supply | Required for dual-supply operation (±4.5V to ±20V); tie to GND for single-supply (+4.5V to +36V) use. |
| GND (Pin 5) | Ground reference | Logic and substrate reference; separate from analog return paths in mixed-signal PCB layout. |
| N.C. (Pin 12) | No connection | Not internally bonded; leave unconnected or float; no routing or stitching required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without distortion or clipping, enabling direct interfacing with op-amp outputs and ADC inputs. |
| Guaranteed RON flatness | ≤2Ω variation over full ±10V signal range ensures consistent gain and linearity in audio and measurement applications. |
| Break-before-make timing | 1–10ns delay prevents momentary shorting between NC and NO paths during switching-critical for protecting downstream circuitry. |
| Low charge injection | ±30pC max minimizes voltage glitches at high-impedance nodes, preserving integrity in sample-and-hold and switched-capacitor circuits. |
| Pin compatibility | Drop-in replacement for MAX314 and industry-standard DG413, simplifying legacy design upgrades without layout changes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314LESE+ | -40°C to +85°C extended temperature range; same 16-pin narrow SO package; identical electrical specs and pinout. | Suitable for automotive engine control or outdoor industrial enclosures where ambient exceeds +70°C. | Select MAX314LESE+ when operating temperature extends beyond 0°C–+70°C; no design change required. |
| ADG413BRZ | 16-pin SOIC; 35Ω typical RON (vs. 10Ω max for MAX314LCUE+); 100nA max off-leakage at +85°C (vs. 2.5nA). | Acceptable for lower-precision, cost-sensitive industrial I/O modules but not for high-fidelity audio or 24-bit DAQ. | Choose ADG413BRZ only if RON >30Ω and leakage >10× higher are acceptable; verify timing and crosstalk fit system requirements. |
Compared with MAX314LESE+, the MAX314LCUE+ trades extended temperature capability for commercial-grade cost and availability; versus ADG413BRZ, it delivers 3.5× lower RON and 40× lower leakage-critical for precision signal chains where gain error and offset drift must be minimized.

FAQ
What is the maximum supply voltage rating for MAX314LCUE+?
The MAX314LCUE+ supports dual supplies from ±4.5V to ±20V or single supply from +4.5V to +36V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V; exceeding these risks permanent damage. For reliable operation, stay within the recommended ranges and observe derating curves in the datasheet's power dissipation section.
Does MAX314LCUE+ require power-supply sequencing?
No-MAX314LCUE+ eliminates the strict sequencing requirements of earlier MAX314 devices. It operates safely with any power-up order of V+, V−, and GND, removing the need for external protection diodes or complex power management. This simplifies system design while maintaining latch-up immunity across its full temperature range.
How does the NC/NO configuration work in MAX314LCUE+?
In MAX314LCUE+, switches 1 and 4 are normally closed (NC): COM1–NC1 and COM4–NC4 conduct when IN1/IN4 = 0V. Switches 2 and 3 are normally open (NO): COM2–NO2 and COM3–NO3 conduct only when IN2/IN3 = +2.0V or higher. This mixed topology allows simultaneous default-path continuity and on-demand routing in safety-critical or reconfigurable systems.
Can MAX314LCUE+ be used in single-supply audio applications?
Yes-MAX314LCUE+ supports single-supply operation from +4.5V to +36V with rail-to-rail signal handling (0V to V+). In audio routing, its 10Ω RON, ≤2Ω flatness, and 96dB crosstalk at 20kHz ensure low THD and channel separation. Use V− tied to GND and ensure logic inputs meet VIH/VIL thresholds referenced to that ground.
What is the thermal performance of MAX314LCUE+ in TSSOP package?
The MAX314LCUE+ in 16-pin TSSOP has a thermal resistance θJA of 149°C/W (typical). At TA = +70°C, its continuous power dissipation is rated at 457mW, derating by 6.7mW/°C above that temperature. The exposed pad (connected to V+) significantly improves heat transfer-PCB layout should include ≥4 thermal vias to inner ground/power planes for optimal thermal performance.
