Product details
Overview
MAX314CUE+ 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, 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail signal handling capability. It operates from single supplies (+4.5V to +30V) or dual supplies (±4.5V to ±20V), and is used in precision audio routing and data acquisition systems where low distortion and tight channel matching are critical.
For engineers reviewing the MAX314CUE+ datasheet, MAX314CUE+ pinout, MAX314CUE+ application, or MAX314CUE+ equivalent, key selection criteria include verified on-resistance flatness (≤2Ω), guaranteed ESD protection (>2000V per Method 3015.7), crosstalk performance (>96dB at 20kHz), and compatibility with DG411/DG412/DG413 pinouts in TSSOP-16 packaging.
Technical Context
The MAX314CUE+ implements a CMOS transmission-gate architecture enabling bidirectional conduction with symmetric on-resistance across signal polarity. Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (logic supply), independent of analog supply rails.
It features break-before-make timing (70ns typ) confirmed for the MAX314 variant, rail-to-rail analog signal range up to ±10V with ±15V supplies, and guaranteed leakage ≤2.5nA at +85°C - critical for high-impedance sample-and-hold and sensor multiplexing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 6.5Ω typical - ensures minimal voltage drop and power loss in signal paths up to ±10V. |
| RON Matching | ≤1.5Ω max between channels - enables precise gain/phase tracking in differential or multi-channel routing. |
| Analog Signal Range | Rail-to-rail: V− to V+ - supports full dynamic range without clipping in bipolar or single-supply configurations. |
| Supply Range | +4.5V to +30V (single); ±4.5V to ±20V (dual) - accommodates industrial, test, and avionics power architectures. |
| Crosstalk | >96dB at 20kHz - prevents audible interference in stereo audio routing and sensitive measurement circuits. |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and field service. |
| Turn-On/Off Time | 225ns/185ns max (TA = TMIN to TMAX) - supports fast switching in automated test equipment and digital control loops. |
Pinout & Package
MAX314CUE+ is housed in a 16-pin TSSOP package (4.4mm width), RoHS-compliant, with exposed pad not electrically connected. Pin layout matches industry-standard DG41x footprints for drop-in replacement in existing layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; active-high for NO channels, active-low for NC channels per truth table. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection points for each SPST switch. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = logic low (MAX314 pins 3/6 = NC; 11/14 = NC). |
| 4, 5, 12, 13 | NO1–NO4 | Normally open analog terminals - conduct to COM only when IN = logic high (MAX314 pins 4/13 = NO; 5/12 = NO). |
| 13 | V+ | Positive analog supply input - sets upper rail for analog signal range and internal biasing. |
| 4 | V− | Negative analog supply input - sets lower rail; tied to GND for single-supply operation. |
| 5 | GND | Logic ground reference - separate from analog supplies to minimize noise coupling. |
| 12 | VL | Logic supply voltage input - decouples logic threshold from analog rails, supporting mixed-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale audio and sensor interfaces. |
| Guaranteed RON flatness | ≤2Ω max variation over full signal range - preserves linearity in precision instrumentation and DAC output switching. |
| Low charge injection | ±30pC max - minimizes voltage glitches in sample-and-hold and switched-capacitor circuits. |
| Break-before-make timing | 70ns typical (MAX314-specific) - prevents momentary shorting in multi-path signal routing. |
| Pin compatibility | Direct replacement for DG411/DG412/DG413 in TSSOP-16 - reduces redesign effort in legacy test and telecom systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX312CUE+ | Quad SPST, all-normally-closed (NC) configuration; identical RON, leakage, and supply specs. | Suitable for fail-safe closed-path designs (e.g., default audio mute, safety interlock). | Select when system requires default-conducting behavior on power loss or logic fault. |
| MAX313CUE+ | Quad SPST, all-normally-open (NO) configuration; same electrical specs and pinout. | Preferred for default-isolated functions (e.g., sensor disconnect on startup, power sequencing). | Choose when initial signal isolation is mandatory before firmware initialization. |
Compared with MAX312CUE+ and MAX313CUE+, the MAX314CUE+ uniquely combines two NC and two NO switches in one TSSOP-16 package - enabling mixed-safety/multiplexing topologies without stacking devices or increasing PCB area.

FAQ
What is the operating temperature range for MAX314CUE+?
The MAX314CUE+ is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its C-grade suffix and TSSOP packaging, making it suitable for indoor industrial controls, lab equipment, and consumer audio systems where extended thermal margins are not required. Full parametric guarantees - including on-resistance, leakage, and switching times - apply across this entire range.
Does MAX314CUE+ support single-supply operation?
Yes, MAX314CUE+ supports single-supply operation from +4.5V to +30V. In this mode, V− is connected to GND, VL is supplied at 5V (typical), and analog signals swing from 0V to V+. The device maintains rail-to-rail signal handling, 6.5Ω typical on-resistance, and ≤2.5nA leakage at +85°C - enabling simplified power design in portable and embedded systems without dual-rail supplies.
How does the MAX314CUE+ pinout differ from MAX312CUE+ and MAX313CUE+?
The MAX314CUE+ shares identical pinout and footprint with MAX312CUE+ and MAX313CUE+ in TSSOP-16. All three use the same pin assignments for V+, V−, GND, VL, IN1–IN4, COM1–COM4, and NO/NC terminals. The functional difference lies solely in internal switch configuration: MAX314CUE+ has IN1/IN4 controlling NC switches and IN2/IN3 controlling NO switches - documented in the truth table and functional diagrams of the datasheet.
Is MAX314CUE+ pin-compatible with DG411/DG412/DG413?
Yes, MAX314CUE+ is explicitly pin-compatible with DG411 (dual NO), DG412 (dual NC), and DG413 (dual NO + dual NC) in 16-pin packages including TSSOP. This compatibility extends to logic thresholds, supply pin locations, and terminal assignments - allowing direct substitution without PCB modification, provided the target application leverages the MAX314's specific two-NC/two-NO topology.
What is the maximum analog signal voltage the MAX314CUE+ can handle?
The MAX314CUE+ supports analog signals from V− to V+, with absolute maximum ratings of −44V to +44V on V+ and V−. When operated with ±15V supplies, it reliably handles ±10V signals (as tested in electrical characteristics). For single-supply use at +12V, the analog range is 0V to +12V. Exceeding V+ or V− clamps signals via internal diodes - limiting safe continuous operation to the specified supply rails.
