Product details
Overview
MAX314LCSE+T from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in ±15V or +12V systems. It delivers ≤10Ω on-resistance, ≤1.5Ω channel-to-channel RON match, and rail-to-rail analog signal handling from –15V to +15V (dual) or 0V to +12V (single), enabling low-distortion audio switching and test equipment multiplexing.
For engineers reviewing the MAX314LCSE+T datasheet, MAX314LCSE+T pinout, MAX314LCSE+T application, or MAX314LCSE+T equivalent, key selection criteria include guaranteed RON flatness (≤2Ω over signal range), +3V logic compatibility (VIH = 2.0V, VIL = 0.8V), break-before-make timing (1–10ns), and dual-/single-supply flexibility (+4.5V to +36V or ±4.5V to ±20V).
Technical Context
The MAX314LCSE+T implements CMOS-based transmission-gate architecture with integrated level-shifting circuitry, enabling direct interface with +3V logic while operating from wide analog supply rails. Its dual-configuration topology-two NC and two NO switches-supports bidirectional signal routing without polarity constraints and maintains <2.5nA off-leakage at +85°C.
It features guaranteed break-before-make timing (tD = 1–10ns) to prevent momentary shorting during channel switching, and achieves >96dB crosstalk rejection at 20kHz. The device eliminates power-supply sequencing requirements, allowing arbitrary V+/V–/GND ramp-up order without latch-up risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match Between Channels | 1.5Ω max - enables matched gain/attenuation across multiple signal paths in instrumentation |
| Analog Signal Range | ±15V (dual) or 0V to +12V (single) - supports rail-to-rail signal handling in industrial and audio circuits |
| Logic Compatibility | +3V logic inputs (VIH = 2.0V, VIL = 0.8V) - interfaces directly with modern microcontrollers and FPGAs without level shifters |
| Turn-On/Turn-Off Time | 275ns / 235ns max - enables fast multiplexing in data-acquisition and communication systems |
| Off-Leakage Current | ±2.5nA at +85°C - preserves signal integrity in high-impedance sample-and-hold and sensor front-ends |
| Crosstalk | >96dB at 20kHz - prevents audible interference in multi-channel audio routing applications |
Pinout & Package
MAX314LCSE+T is housed in a 16-pin narrow SO package (package code S16-8), with 1.27mm pitch, 10.3mm × 5.3mm body, and exposed pad not present (non-QFN). Pin functions are fully defined per Maxim's official pin description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Accept +3V-compatible digital signals to actuate corresponding switches; inverted logic for NC channels |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Bidirectional signal path junctions; connect to source/load in SPST configuration |
| NC1, NC2, NO3, NO4 (Pins 3, 6, 11, 14) | Analog switch terminals | Pins 3 & 6 = NC; Pins 11 & 14 = NO - defines mixed-configuration routing capability |
| V+ (Pin 13) | Positive analog supply | Accepts +4.5V to +36V (single) or +4.5V to +20V (dual); powers internal switch core and level shifter |
| V− (Pin 4) | Negative analog supply | Accepts –4.5V to –20V (dual); tied to GND for single-supply operation |
| GND (Pin 5) | Ground reference | Logic and substrate reference; must be low-impedance for noise-sensitive analog routing |
| N.C. (Pin 12) | No connection | Not internally bonded - leave unconnected; no electrical function or thermal role |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NC/NO configuration | Two NC + two NO SPST switches in one IC - enables flexible signal path selection without external logic |
| Break-before-make timing | 1–10ns guaranteed - prevents transient short-circuits during channel transitions in critical analog routing |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - preserves full dynamic range in ±15V op-amp and DAC interfaces |
| +3V logic compatibility | VIH = 2.0V, VIL = 0.8V - eliminates need for external level translators when driven by 3.3V microcontrollers |
| Supply sequencing immunity | No VL pin or strict V+/V− ramp order required - simplifies power architecture in multi-rail systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314CSE+ | Legacy non-L version; higher RON (15Ω max), no guaranteed break-before-make, requires VL bias pin | Lacks supply sequencing immunity and tighter RON specs; unsuitable for new designs requiring robustness | Select MAX314LCSE+T for improved leakage, timing control, and simplified power design |
| ADG414BRZ | Quad SPST, 35Ω RON, 3V logic compatible, but only single-supply (12V max); no NC/NO mixing | Higher on-resistance limits use in low-voltage precision paths; lacks dual-supply flexibility for ±15V systems | Choose MAX314LCSE+T when rail-to-rail bipolar signal handling or mixed switch topology is required |
Compared with MAX314CSE+ and ADG414BRZ, the MAX314LCSE+T uniquely combines mixed NC/NO topology, guaranteed break-before-make, dual-supply support up to ±20V, and sub-10Ω RON - making it optimal for high-fidelity, high-reliability analog routing where supply flexibility and channel coordination matter.

FAQ
What is the maximum supply voltage range supported by the MAX314LCSE+T?
The MAX314LCSE+T operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. Absolute maximum ratings allow V+ up to +44V and V− down to –44V, but functional operation is specified only within the stated ranges. Exceeding ±20V on dual supplies may degrade RON matching and increase leakage beyond datasheet limits.
Does the MAX314LCSE+T require power-supply sequencing?
No - the MAX314LCSE+T eliminates the VL pin and associated sequencing constraints of earlier MAX314 variants. It supports arbitrary ramp-up order of V+, V−, and GND without latch-up risk. This simplifies power system design in multi-rail platforms, though absolute maximum ratings must still be observed during startup transients.
How does the mixed NC/NO configuration of the MAX314LCSE+T work in practice?
The MAX314LCSE+T integrates two normally closed (NC1, NC2) and two normally open (NO3, NO4) SPST switches. When IN1/IN2 are logic low, COM1/COM2 connect to NC1/NC2; when IN3/IN4 are logic high, COM3/COM4 connect to NO3/NO4. This allows independent control of fail-safe and active-enable paths in safety-critical or redundancy-driven systems.
What is the guaranteed break-before-make time for the MAX314LCSE+T?
The MAX314LCSE+T guarantees a break-before-make time delay (tD) of 1ns to 10ns under standard test conditions (RL = 300Ω, CL = 35pF). This parameter applies only to the internal coordination between its two NO and two NC switch pairs - it ensures no overlap during state transitions, preventing momentary shorts in sensitive analog signal chains.
Can the MAX314LCSE+T be used in single-supply audio applications?
Yes - the MAX314LCSE+T supports single-supply operation from +4.5V to +36V with rail-to-rail analog signal handling (0V to V+). In +12V audio systems, it achieves ≤35Ω RON, <–80dB THD at 1kHz, and >96dB crosstalk at 20kHz, making it suitable for line-level routing in consumer and pro-audio gear where ground-referenced signals dominate.
