Product details
Overview
MAX4514C/D from Maxim Integrated is a single-pole/single-throw (SPST), normally open (NO), CMOS analog switch optimized for low-voltage, rail-to-rail signal routing. It operates from +2V to +12V single supply, delivers 20Ω on-resistance at +5V, supports ≤1nA off-leakage at +25°C, and features 150ns turn-on time - enabling precision signal switching in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4514C/D datasheet, MAX4514C/D pinout, MAX4514C/D application, or MAX4514C/D equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), break-before-make timing behavior, TTL/CMOS logic compatibility at +5V, and SOT23-5 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4514C/D implements a CMOS transmission-gate architecture with dual ESD diodes per analog terminal (to V+ and GND), enabling rail-to-rail analog signal handling while limiting off-leakage to 1nA at +25°C. Its digital control input accepts 0.8V–2.4V logic thresholds when V+ = +5V, ensuring direct interface with standard TTL/CMOS outputs without level-shifting.
Switching dynamics are defined by charge injection (10pC typical) and capacitive coupling: COM on-capacitance is 30pF, off-isolation reaches –90dB at 100kHz, and tON > tOFF ensures break-before-make operation at +5V - critical for preventing signal shorting during state transitions in multiplexed sensor or audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - supports direct integration into 3.3V, 5V, and 12V systems without auxiliary rails. |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level analog paths (e.g., sensor front-ends). |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement circuits (e.g., pH sensors, thermocouple amplifiers). |
| Turn-On/Off Time | tON = 150ns, tOFF = 100ns - enables reliable switching in 1MHz sampling applications with minimal transient glitching. |
| Charge Injection | 10pC typical - limits output voltage step error (ΔVOUT) to <10mV into 1nF load, critical for sample-and-hold stability. |
| Logic Compatibility | 0.8V–2.4V input thresholds at +5V supply - allows direct connection to 5V microcontroller GPIOs without external translators. |
| Analog Signal Range | Rail-to-rail (0V to V+) - supports full-scale signal routing across entire supply range, including near-GND and near-V+ levels. |
Pinout & Package
MAX4514C/D is supplied in die form (dice) with no molded package; it is intended for hybrid or custom module integration. The functional pin mapping matches the SOT23-5 variant: Pin 1 = NO (normally open switch terminal), Pin 2 = IN (digital control input), Pin 3 = GND (ground reference), Pin 4 = COM (common analog terminal), Pin 5 = V+ (positive supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NO | Normally open analog switch terminal | Open-circuit when IN = LOW; connects to COM only when IN = HIGH - prevents unintended signal path closure during power-up or reset. |
| IN | Digital control input | Active-high logic input; drives internal CMOS gates; compatible with 5V TTL/CMOS without pull-ups or level shifters. |
| GND | Analog and digital ground reference | Common return for all analog signals and internal logic; must be low-impedance to minimize noise coupling into sensitive analog paths. |
| COM | Common analog terminal | Bidirectional signal node - functions as input or output depending on system topology; shares same voltage range as NO/NC terminals. |
| V+ | Positive supply for analog and digital circuitry | Powers internal transmission gates and logic translators; sets absolute analog signal limits (0V to V+); internally ties substrate. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | tON > tOFF at +5V ensures no overlap between old and new signal paths - eliminates momentary shorts in multiplexer configurations. |
| Low on-resistance flatness | ≤3Ω variation over full analog signal range (0V to V+) - maintains consistent gain and linearity across DC to 100kHz signals. |
| Guaranteed leakage performance | 1nA off-leakage at +25°C, tested 100% at max hot temperature - provides predictable error budget for precision instrumentation designs. |
| Rail-to-rail analog capability | Supports signals from 0V to V+ with no degradation - enables direct interfacing with op-amp outputs, DACs, and ADC inputs operating at supply rails. |
| ESD-protected analog terminals | Internal diodes clamp signals exceeding V+ or GND - protects against ±2000V HBM ESD without requiring external TVS devices. |
Applications
| Portable Audio Signal Routing | Low-Power Data Acquisition Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CSA | SOP-8 packaged version; identical electrical specs but larger footprint and higher thermal resistance (471mW vs. dice thermal limit). | Preferred for prototyping or low-volume PCBs where reflow compatibility and test access matter more than size or thermal performance. | Select MAX4514CSA when board assembly uses standard SOIC footprints and thermal dissipation is not constrained. |
| ADG1419BRMZ | Single SPST switch with 0.7Ω RON at +15V, but requires dual ±15V supplies or +12V single supply; 15pC charge injection. | Better suited for high-precision, high-voltage industrial DAQ where ultra-low RON outweighs supply complexity and leakage (2nA off-leakage at +25°C). | Choose ADG1419BRMZ only if system already uses ±15V rails and demands sub-1Ω on-resistance - not a drop-in replacement for MAX4514C/D. |
Compared with MAX4514CSA, the MAX4514C/D offers superior thermal density and board-space efficiency for embedded modules, while ADG1419BRMZ trades higher supply complexity and leakage for dramatically lower on-resistance in high-voltage precision applications.

FAQ
What is the maximum supply voltage rating for MAX4514C/D?
The MAX4514C/D has an absolute maximum V+ rating of +13V. Continuous operation is specified from +2V to +12V. Exceeding +13V risks permanent damage due to internal ESD diode breakdown. For reliable long-term use, maintain V+ within the recommended +2V to +12V range, with derating applied above +70°C ambient per the 7.1mW/°C thermal spec for SOT23-5 equivalents.
Does MAX4514C/D support bidirectional analog signal flow?
Yes, the MAX4514C/D supports fully bidirectional analog signal routing between the NO and COM terminals. Its CMOS transmission-gate structure imposes no inherent directionality - signals pass with equal fidelity from NO to COM or COM to NO, provided voltage levels remain within the 0V to V+ range and current stays below ±20mA continuous rating.
Can MAX4514C/D operate from a +3.3V supply?
Yes, the MAX4514C/D is fully specified for +3V to +3.6V operation. At +3.3V, on-resistance is typically 50Ω (max 75Ω), turn-on time is 150ns, and off-leakage remains ≤1nA at +25°C. Logic thresholds scale with V+, so a +3.3V-compatible controller (e.g., 3.3V GPIO) must drive the IN pin to ensure reliable switching.
What is the thermal limitation of MAX4514C/D in die form?
As a die, MAX4514C/D has no fixed package thermal resistance; its junction temperature depends entirely on the host substrate's thermal design. Reference data from the SOT23-5 variant indicates a 7.1mW/°C derating factor above +70°C. Users must ensure the die-mounting interface (e.g., ceramic substrate, metal-core PCB) maintains TJ ≤ +125°C under worst-case power dissipation (I2R losses + supply current).
How does charge injection affect sample-and-hold circuits using MAX4514C/D?
MAX4514C/D's 10pC typical charge injection causes a voltage step ΔVOUT = Q / CL on the hold capacitor. With a 1nF capacitor, this yields ≤10mV error - manageable in 12-bit systems (LSB ≈ 2.4mV at 5V full-scale) but requiring additional settling time. For higher resolution, use smaller hold capacitors or add a buffer amplifier to isolate the switch from CL.
