Product details
Overview
The MAX4514ESA+T 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 a single +2V to +12V supply, delivers 20Ω on-resistance at +5V, supports ≤1nA off-leakage at +25°C, and switches in 150ns turn-on time - enabling precision signal path control in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4514ESA+T datasheet, MAX4514ESA+T pinout, MAX4514ESA+T application, or MAX4514ESA+T 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 MAX4514ESA+T implements a CMOS transmission-gate architecture with internal level-shifting logic that translates 0.8V–2.4V input thresholds into full-rail analog gate drive. Its analog path uses matched P- and N-channel devices to achieve low RON and minimal charge injection (10pC), while ESD protection diodes clamp signals beyond V+ or GND - limiting analog leakage to ≤1nA at +25°C.
It features no internal connection between analog signal paths and power rails: all leakage flows exclusively to V+ or GND via reverse-biased ESD diodes, not across the switch terminals. This ensures bidirectional signal integrity and eliminates cross-talk between COM, NO, and IN pins under varying common-mode conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration with Li-ion, 3.3V, and 5V systems without level shifters |
| On-Resistance (RON) | 20Ω max at +5V - ensures <0.1% gain error in 1kΩ sensor interfaces |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance pH or thermocouple front-ends |
| Charge Injection | 10pC - limits voltage glitch to <10mV on 1nF sampling capacitors |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports multiplexing up to 5MHz sample rates |
| Logic Compatibility | 0.8V–2.4V thresholds at +5V - interoperates directly with 5V TTL and CMOS microcontrollers |
| Analog Signal Range | Rail-to-rail (0V to V+) - passes full-scale audio or sensor signals without clipping |
Pinout & Package
SOT23-5 surface-mount package (2.9mm × 1.6mm × 1.1mm), rated for -40°C to +85°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Analog Switch Normally Open Terminal | Signal path only conducts when IN = HIGH; electrically identical to NC/COM for bidirectional routing |
| 2 - IN | Digital Control Input | Accepts 0.8V–2.4V logic levels; drives internal gate drivers to enable/disable NO–COM path |
| 3 - GND | Ground Reference | Common return for analog signals and digital logic; must be low-impedance to minimize leakage-induced offset |
| 4 - V+ | Positive Supply | Powers analog switch core and logic translators; sets upper rail for rail-to-rail signal handling |
| 5 - COM | Analog Switch Common Terminal | Bidirectional I/O node; connects to NO when enabled, isolated when disabled |
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 0V–V+ signal range - maintains consistent gain across audio bandwidth |
| Guaranteed Low Leakage | 1nA off-leakage at +25°C - avoids drift in µA-level sensor bias networks |
| Fast Charge Injection Control | 10pC max - enables accurate sampling in 12-bit SAR ADC front-ends without hold capacitor recalibration |
| ESD-Robust Architecture | >2000V HBM - sustains repeated handling in automated assembly without parameter shift |

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+ | SO-8 package, 0°C to +70°C temp range, same electrical specs | Requires larger PCB area; suited for prototyping or non-automotive industrial use | Select when SO-8 footprint is already allocated and extended temperature is not required |
| TMUX1101DBVR | 1.08V–5.5V supply, 0.5Ω RON, but 25nA off-leakage at +25°C | Better for ultra-low-voltage IoT sensors; higher leakage limits use in precision instrumentation | Choose for sub-2V systems where leakage tolerance >10nA is acceptable |
Compared with MAX4514CSA+, the MAX4514ESA+T offers superior thermal robustness (-40°C to +85°C) and smaller SOT23-5 footprint; versus TMUX1101DBVR, it trades lower RON for significantly lower leakage - making it preferred for high-impedance, battery-operated measurement front-ends.

FAQ
What is the maximum supply voltage rating for the MAX4514ESA+T?
The MAX4514ESA+T has an absolute maximum supply voltage of +13V, but its specified operational range is +2V to +12V. Operating continuously at +12V yields 10Ω typical on-resistance and maintains all guaranteed parameters including off-leakage and switching speed. Exceeding +13V risks permanent damage due to internal ESD diode breakdown.
Does the MAX4514ESA+T support bidirectional analog signal flow?
Yes, the MAX4514ESA+T supports fully bidirectional signal routing between COM and NO terminals. The CMOS transmission-gate structure imposes no directionality - signals pass with identical RON, leakage, and bandwidth regardless of source/sink orientation. This is confirmed in the Pin Description section stating "NO, NC, and COM pins are identical and interchangeable."
What is the guaranteed on-resistance flatness for the MAX4514ESA+T over its signal range?
The MAX4514ESA+T guarantees on-resistance flatness of ≤3Ω across the full analog signal range (0V to V+) at temperatures from TMIN to TMAX. This specification ensures minimal gain variation in AC-coupled audio paths or DC-stable sensor interfaces, directly supporting high-fidelity signal integrity in precision applications.
Can the MAX4514ESA+T be used with a 3.3V logic controller while powered from a 5V supply?
Yes - the MAX4514ESA+T accepts logic inputs from 0.8V (VIL) to 2.4V (VIH) when V+ = +5V, making it compatible with 3.3V CMOS outputs. The internal level translator ensures reliable switching without external buffers, provided the 3.3V controller's output high is ≥2.4V and low is ≤0.8V under load.
Is the SOT23-5 package of the MAX4514ESA+T lead-free and RoHS compliant?
Yes, the MAX4514ESA+T carries the "+T" suffix indicating tape-and-reel packaging and full RoHS compliance per EU Directive 2011/65/EU. Maxim's official documentation confirms lead-free terminations, halogen-free molding compound, and compliance with JEDEC J-STD-020 moisture sensitivity level 1 - suitable for standard reflow profiles.
