Product details
Overview
MAX314LCSE+ 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 analog handling and low channel mismatch are critical.
For engineers reviewing the MAX314LCSE+ datasheet, MAX314LCSE+ pinout, MAX314LCSE+ application, or MAX314LCSE+ equivalent, key selection criteria include verified RON matching (≤1.5Ω), break-before-make timing (1–10ns), off-isolation (>75dB at 1MHz), and compatibility with industrial-grade SO-16 narrow-body packaging for space-constrained PCB layouts.
Technical Context
The MAX314LCSE+ implements four independent CMOS SPST switches in a single monolithic die, with dedicated NC/NO topology per channel pair - pins 3/6 drive NO1/NO4, while pins 11/14 drive NC3/NC2. Its architecture supports bidirectional signal conduction and rail-to-rail analog voltage ranges from V− to V+, with no internal level-shifting circuitry required.
It features guaranteed RON flatness ≤4Ω over full signal range and operates without power-supply sequencing constraints - V+, V−, and logic inputs may power up in any order within absolute maximum ratings. Charge injection is specified at ±30pC (dual supply) and ±10pC (single supply), enabling low-glitch switching in sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at ±15V dual supply; ensures minimal signal attenuation and gain error in precision instrumentation paths. |
| RON Match Between Channels | 1.5Ω max; guarantees matched gain/phase response across channels in differential or multi-path signal routing. |
| Analog Signal Range | V− to V+; supports true rail-to-rail input/output swing, including negative voltages down to −20V in dual-supply mode. |
| Logic Compatibility | +3V compatible (VIH = 2.0V, VIL = 0.8V); interfaces directly with 3.3V microcontrollers without level shifters. |
| Turn-On/Turn-Off Time | 275ns / 235ns max (dual supply); enables reliable switching in audio-band and medium-speed data acquisition (<500kHz). |
| Off-Isolation | −75dB at 1MHz; suppresses crosstalk between inactive channels in high-density multiplexer designs. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual); accommodates legacy industrial rails and modern wide-input systems. |
Pinout & Package
MAX314LCSE+ is housed in a 16-pin narrow SO package (package code S16-8), 7.5mm × 5.0mm body, 1.27mm pitch, with gull-wing leads and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 (Pins 1, 8, 9, 16) | Logic Control Inputs | Digital enable signals for respective SPST switches; active-high, +3V logic compatible. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog Common Terminals | Bidirectional signal path junctions; connect to source/load in SPST configuration. |
| NC1, NC2 (Pins 11, 14) | Normally Closed Analog Terminals | Connected to COMx when INx = logic low; default path for fail-safe signal continuity. |
| NO1, NO4 (Pins 3, 6) | Normally Open Analog Terminals | Connected to COMx when INx = logic high; used for controlled signal insertion or gating. |
| V+ (Pin 13) | Positive Analog Supply | Primary positive rail; must be ≥+4.5V (single) or ≤+20V (dual); connects to exposed pad in QFN variants. |
| V− (Pin 4) | Negative Analog Supply | Required for dual-supply operation; tie to GND for single-supply use (0V to V+). |
| GND (Pin 5) | Ground Reference | Logic and substrate reference; separate from analog return paths in mixed-signal layouts. |
| N.C. (Pin 12) | No Connection | Internally unconnected; must remain floating or grounded per layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| Two NC + Two NO topology | Enables hybrid signal routing - e.g., default analog path (NC) plus on-demand bypass (NO) in fault-tolerant test equipment. |
| Break-before-make timing | 1–10ns guaranteed (MAX314L only); prevents momentary short-circuits during channel switching in sensitive analog nodes. |
| Rail-to-rail signal handling | Supports input/output signals spanning full V− to V+ range; eliminates clipping in ±12V op-amp or audio amplifier interfaces. |
| Low charge injection (±10pC) | Minimizes voltage glitch on hold capacitors; critical for <16-bit accuracy in switched-capacitor ADC front-ends. |
| Pin compatibility with DG411/DG412/DG413 | Allows drop-in replacement in legacy designs using industry-standard 16-pin SO footprints and truth tables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314LESE+ | Extended temperature range (−40°C to +85°C) vs. MAX314LCSE+ (0°C to +70°C); identical electrical specs and pinout. | Suitable for automotive or outdoor industrial deployments where ambient extremes exceed commercial grade limits. | Select MAX314LESE+ when operating outside 0°C–70°C or requiring AEC-Q200-aligned qualification evidence. |
| ADG414BRZ | Quad SPST, +3V logic compatible, but higher RON (35Ω typ), no guaranteed RON match spec, and no break-before-make timing guarantee. | Better suited for non-critical general-purpose switching where cost is prioritized over precision matching or glitch control. | Choose ADG414BRZ only if RON flatness, channel matching, and sub-10ns timing are not design requirements. |
Compared with MAX314LESE+, the MAX314LCSE+ trades extended temperature capability for lower cost and qualification overhead in commercial-grade systems; versus ADG414BRZ, it delivers superior precision (1.5Ω RON match vs. unspecified), deterministic timing (guaranteed tD), and tighter leakage control (±2.5nA vs. ±5nA), making it essential for metrology-class signal routing.

FAQ
What is the maximum supply voltage rating for MAX314LCSE+?
The MAX314LCSE+ supports single-supply operation from +4.5V to +36V and dual-supply operation from ±4.5V to ±20V. Absolute maximum ratings specify V+ up to +44V and V− down to −44V, but sustained operation beyond ±20V or +36V violates datasheet limits and risks permanent damage. Always observe the recommended operating ranges defined in the Electrical Characteristics tables for reliable performance.
Does MAX314LCSE+ require power-supply sequencing?
No, the MAX314LCSE+ does not require power-supply sequencing. Unlike earlier MAX312/MAX313/MAX314 generations, the L-series eliminates the VL pin and allows V+, V−, and logic inputs to power up in any order - provided all pins remain within their absolute maximum ratings. This simplifies power architecture design and removes latch-up risk in systems with asynchronous rail ramp-up.
What is the function of Pin 12 (N.C.) on MAX314LCSE+?
Pin 12 on the MAX314LCSE+ is a no-connect (N.C.) terminal - it is not bonded internally and has no electrical function. Per Maxim's datasheet, this pin must remain unconnected in the PCB layout. While grounding it poses no functional harm, leaving it floating is preferred to avoid unintended coupling or noise pickup in high-impedance analog sections near the device.
How does the MAX314LCSE+ differ from MAX312LCSE+ and MAX313LCSE+?
The MAX314LCSE+ integrates two normally closed (NC) and two normally open (NO) SPST switches in one package, whereas MAX312LCSE+ contains four NC switches and MAX313LCSE+ contains four NO switches. All three share identical pinouts, supply ranges, RON, and timing specs - only the default switch state per channel differs. This allows flexible system-level redundancy (NC) and controlled activation (NO) within a single footprint.
Can MAX314LCSE+ operate from a single +5V supply?
Yes, the MAX314LCSE+ supports single-supply operation down to +4.5V, so +5V is fully compliant. However, RON increases significantly at low V+: typical RON rises to ~35Ω at +5V (vs. 10Ω at ±15V), and analog signal range shrinks to 0V to +5V. For low-RON performance, use ≥+12V single supply or ±12V dual supply - always verify RON vs. VCOM curves in the Typical Operating Characteristics section.
