Product details
Overview
MAX4514ESA 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 - ideal for precision audio routing and battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4514ESA datasheet, MAX4514ESA pinout, MAX4514ESA application, or MAX4514ESA equivalent, this page provides verified electrical parameters, SOT23-5 package mapping, break-before-make timing behavior, TTL/CMOS logic compatibility at +5V, and validated alternatives for low-leakage SPST switching in portable and industrial signal-path designs.
Technical Context
The MAX4514ESA implements a fully CMOS transmission-gate architecture with dual-channel ESD protection diodes tied to V+ and GND on all analog pins. Its digital control input drives internal level translators that generate full-rail gate voltages, enabling rail-to-rail analog conduction without degradation across the +2V to +12V supply range.
Break-before-make timing is guaranteed (tON > tOFF at +5V), preventing momentary shorting during state transitions. Charge injection is tightly controlled at 10pC (typ), minimizing transient glitches in sampled-data systems - critical for high-resolution ADC/DAC interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery-powered systems without level-shifting. |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and THD degradation in audio and sensor signal paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor front-ends and precision reference switching. |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports multiplexing of DC–250MHz signals in instrumentation and comms circuits. |
| Charge Injection | 10pC max - limits voltage glitch on capacitive loads (e.g., ADC sample capacitors) to <1mV with 1nF load. |
| Logic Compatibility | 0.8V to 2.4V thresholds at +5V - ensures reliable drive from standard TTL and CMOS outputs without external buffers. |
| Analog Signal Range | Rail-to-rail (GND to V+) - allows full-scale signal handling in unipolar and bipolar (with offset) configurations. |
Pinout & Package
SOT23-5 surface-mount package (5-pin, 1.75mm × 2.9mm footprint), rated for -40°C to +85°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Analog Switch Terminal (Normally Open) | Open-circuit when IN = LOW; connects to COM only when switch is enabled - defines SPST NO topology. |
| 2 - IN | Digital Control Input | Active-HIGH logic input; drives internal level translator to fully enhance NMOS/PMOS transmission gate. |
| 3 - GND | Ground Reference | Common return for analog and digital circuitry; substrate tied internally to V+, not GND. |
| 4 - V+ | Positive Supply | Powers analog switch core and digital logic; sets absolute analog signal ceiling (GND to V+). |
| 5 - COM | Analog Switch Common Terminal | Shared node for bidirectional signal flow; connects to NO when enabled, otherwise isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Low On-Resistance Flatness | ≤3Ω variation over full analog signal range - maintains consistent gain and linearity in variable-gain stages. |
| Guaranteed Break-Before-Make | tON > tOFF at +5V - eliminates cross-conduction risk in multiplexer banks and relay-replacement circuits. |
| Ultra-Low Off-Leakage | 20nA max at +85°C - sustains measurement integrity in thermocouple, pH probe, and medical sensor interfaces. |
| Minimal Charge Injection | 10pC max - reduces settling error in switched-capacitor filters and sample-and-hold circuits. |
| ESD-Robust Analog Pins | Internal diodes to V+/GND - protects against ±2000V HBM ESD without requiring external clamps in most layouts. |
Applications
| Audio Signal Routing | Portable Data Acquisition |
|---|---|
|
Use Scenario: Selecting between microphone inputs or routing line-level audio in Bluetooth headsets and voice recorders. IC Role / Device Role / Timing Role: SPST analog switch controlling signal path continuity with sub-150ns switching and <0.01% THD at 1kHz. Use Value: Enables zero-crossing mute control and channel selection without pop/click artifacts due to 10pC charge injection and rail-to-rail swing. |
Use Scenario: Multiplexing thermistor, RTD, or strain gauge signals into a single ADC channel in handheld test equipment. IC Role / Device Role / Timing Role: Low-leakage analog switch isolating high-impedance sensors during idle cycles to prevent bias current errors. Use Value: 1nA off-leakage at +25°C ensures <0.1µV offset error in 10MΩ sensor bridges, preserving 16-bit effective resolution. |
| PCMCIA Interface Switching | Modem Line-Switching |
|
Use Scenario: Enabling/disabling analog audio codec connections in legacy PCMCIA modem or sound cards. IC Role / Device Role / Timing Role: Single-supply SPST switch interfacing 3.3V logic control with 5V analog codec rails via level-tolerant IN pin. Use Value: +2V to +12V operation allows direct use with both 3.3V and 5V PCMCIA bus supplies without external regulators. |
Use Scenario: Isolating DAA (Data Access Arrangement) circuitry from line-side transients during modem power-down sequences. IC Role / Device Role / Timing Role: Normally-open switch disconnecting analog line interface when modem enters sleep mode. Use Value: 20Ω RON minimizes insertion loss (<0.2dB at 4kHz), while 20nA leakage at +85°C prevents false ring detection. |
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 - larger footprint, lower thermal resistance, no exposed pad. | Preferred for prototyping, through-hole boards, or higher-power dissipation scenarios (>1mW avg). | Select when board space permits SO-8 and ambient temperature stays within commercial range. |
| TMUX1101DBVR | 1.08Ω RON at +5V, 1.5pC charge injection, but 1.6V–5.5V supply only - no +12V support. | Better for ultra-low-distortion audio or high-speed sampling, but unsuitable for 9V/12V battery systems. | Choose only if supply is strictly ≤5.5V and sub-2pC charge injection is mandatory for your ADC architecture. |
Compared with MAX4514CSA and TMUX1101DBVR, the MAX4514ESA uniquely balances wide supply flexibility (+2V to +12V), SOT23-5 compactness, and 1nA leakage - making it the only option among the three qualified for extended-temperature, space-constrained, multi-rail portable designs.

FAQ
What is the maximum supply voltage rating for MAX4514ESA?
The MAX4514ESA has an absolute maximum V+ rating of +13V, but its specified operational range is +2V to +12V. Operation at +12V yields optimal performance: 10Ω typical on-resistance and guaranteed break-before-make timing. Exceeding +13V risks permanent damage due to internal ESD diode breakdown.
Does MAX4514ESA support bidirectional analog signal flow?
Yes, the MAX4514ESA supports fully bidirectional signal routing between NO and COM terminals. The CMOS transmission-gate structure imposes no inherent directionality - voltage, current, and frequency response are identical regardless of signal direction, as confirmed in the Pin Description section of the datasheet.
What is the guaranteed on-resistance flatness for MAX4514ESA?
The MAX4514ESA guarantees on-resistance flatness (∆RON) of ≤3Ω over the full analog signal range (GND to V+) at temperatures from TMIN to TMAX. This tight flatness ensures minimal harmonic distortion and gain variation in audio and instrumentation amplifier signal paths.
Can MAX4514ESA be used with a 3.3V logic controller while powered from a 5V supply?
Yes - the MAX4514ESA's digital input (IN) has TTL/CMOS-compatible thresholds (0.8V to 2.4V at +5V supply), so a 3.3V logic HIGH (≥2.4V) reliably turns the switch ON. No level shifter is needed, provided the 3.3V controller's output does not exceed V+ (5V) or go below GND.
Is the exposed pad on the MAX4514ESA SOT23-5 package electrically connected?
No - the exposed pad on the MAX4514ESA SOT23-5 package is not internally connected to any die node. It may be left floating or soldered to a thermal pad for improved heat dissipation, but must not be tied to V+, GND, or any other voltage per Maxim's recommended layout guidelines.
