Product details
Overview
MAX4514EUA 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 switching in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4514EUA datasheet, MAX4514EUA pinout, MAX4514EUA application, or MAX4514EUA equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), break-before-make timing (tON > tOFF), TTL/CMOS logic compatibility at +5V, and SOT23-5 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4514EUA implements a CMOS transmission-gate architecture with internal level translators that convert 0.8V–2.4V logic inputs into full-rail analog gate drive signals. Its analog path uses matched P- and N-channel MOSFETs to achieve rail-to-rail signal handling and low charge injection (10pC).
ESD protection diodes are integrated between each analog terminal (COM, NO) and both V+ and GND, defining absolute maximum ratings and governing leakage behavior across temperature. Off-isolation exceeds –90dB at 100kHz, while on-capacitance is 30pF and off-capacitance is 14pF - critical for high-fidelity audio and broadband signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration with Li-ion, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement circuits (e.g., pH sensors, thermocouples). |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports multiplexing of fast data streams up to ~1MHz without timing skew. |
| Charge Injection | 10pC max - limits voltage glitch on sampled-hold capacitors, critical for ADC front-end stability. |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - guarantees reliable control from standard 5V TTL/CMOS microcontrollers. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-swing AC/DC signal routing without clipping or distortion. |
Pinout & Package
SOT23-5 surface-mount package (2.9mm × 1.6mm footprint, 1.1mm height), rated for –40°C to +85°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open Switch Terminal | Signal path remains open until IN is HIGH; bidirectional - usable as input or output. |
| 2 - IN | Digital Control Input | Active-HIGH logic input; accepts 0.8V–2.4V thresholds at +5V supply for direct MCU interfacing. |
| 3 - GND | Analog/Digital Ground Reference | Common return for V+, logic, and analog paths; must be low-impedance to minimize noise coupling. |
| 4 - V+ | Positive Supply Rail | Powers analog switch core and logic translator; also ties substrate - must be stable and filtered. |
| 5 - COM | Common Analog Terminal | Central connection point; routes signal to NO when enabled; bidirectional and rail-to-rail capable. |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Timing | tON > tOFF at +5V prevents momentary short-circuits during channel switching in multiplexer arrays. |
| Low On-Resistance Flatness | ≤3Ω variation over full analog range - maintains consistent gain and THD across signal amplitude. |
| Guaranteed Leakage Performance | 100% tested at +85°C for off-leakage; correlation-validated at +25°C - ensures reliability in extended-temp designs. |
| ESD Robustness | >2000V per Method 3015.7 - reduces field failure risk in handheld and industrial assembly environments. |
| Small-Signal Bandwidth | Flat response to 250MHz in 50Ω systems - supports video, RF sampling, and high-speed serial routing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514ESA | Same electrical specs; SO-8 package (4.9mm × 6.0mm), higher thermal mass, 471mW dissipation limit. | Better suited for prototyping, manual soldering, or higher-power analog stages where board space permits. | Select MAX4514ESA when layout allows larger footprint and thermal performance outweighs size constraints. |
| TMUX1574DRYR | Lower RON (0.5Ω typ), but requires dual supply (±2.5V) or level-shifter for 5V logic; 1.5pC charge injection. | Optimized for ultra-low-distortion instrumentation, not direct drop-in replacement for single-supply +5V systems. | Choose TMUX1574DRYR only if redesigning for dual supply and sub-1Ω RON is mandatory for your signal chain. |
Compared with MAX4514ESA, the MAX4514EUA offers identical switching performance in a 60% smaller footprint and lower thermal resistance - ideal for miniaturized portable designs. Against TMUX1574DRYR, it trades lower RON for true single-supply simplicity and guaranteed 1nA leakage at +25°C without external biasing.

FAQ
What is the maximum operating temperature range for the MAX4514EUA?
The MAX4514EUA is specified for operation from –40°C to +85°C. This extended temperature grade is validated per the datasheet's "MAX4514E_ _" ordering suffix and confirmed by 100% testing at +85°C for leakage parameters, making it suitable for industrial and automotive cabin applications where ambient temperatures exceed commercial-grade limits.
Does the MAX4514EUA require external pull-up or pull-down resistors on its IN pin?
No, the MAX4514EUA does not require external biasing on the IN pin. Its digital input has guaranteed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high at +5V supply) and draws ≤0.03µA input current, allowing direct connection to microcontroller GPIOs without additional components - simplifying layout and reducing BOM count for the MAX4514EUA.
Can the MAX4514EUA safely switch signals beyond its V+ rail?
No. The MAX4514EUA's absolute maximum rating specifies that voltages at any terminal must stay within –0.3V to (V+ + 0.3V). Exceeding this range forward-biases internal ESD diodes, risking permanent damage. For signals exceeding V+, use external clamping or select a switch with higher rail tolerance - the MAX4514EUA is strictly limited to rail-to-rail operation.
Is the SOT23-5 package of the MAX4514EUA lead-free and RoHS compliant?
Yes, the MAX4514EUA in SOT23-5 packaging is lead-free and RoHS compliant, as confirmed by Maxim's official product change notices and packaging specifications. The device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is compatible with standard reflow profiles, ensuring reliable assembly for the MAX4514EUA in modern green manufacturing lines.
How does the MAX4514EUA's on-resistance vary with supply voltage?
The MAX4514EUA's on-resistance decreases with increasing supply voltage: 20Ω max at +5V, 10Ω max at +12V, and 50Ω max at +3V. This inverse relationship stems from enhanced MOSFET channel conduction - designers must account for RON drift when using variable supplies, as the MAX4514EUA's signal path loss and THD will scale accordingly.
