Product details
Overview
MAX4514EPA 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 - ideal for precision battery-powered audio switching and low-voltage data acquisition.
For engineers reviewing the MAX4514EPA datasheet, MAX4514EPA pinout, MAX4514EPA application, or MAX4514EPA equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), break-before-make timing behavior, TTL/CMOS logic compatibility at +5V, and -40°C to +85°C industrial temperature range compliance.
Technical Context
The MAX4514EPA uses complementary MOSFET architecture with integrated level translators enabling full rail-to-rail analog signal handling across its COM–NO path. Its digital control input accepts 0.8V–2.4V logic thresholds when V+ = +5V, ensuring direct interface with standard microcontroller GPIOs without external level shifting.
Internal ESD protection diodes clamp analog pins to V+ and GND, defining absolute maximum signal range as -0.3V to (V+ + 0.3V). Leakage current originates exclusively from reverse-biased ESD diodes - not inter-terminal conduction - and scales predictably with temperature and supply voltage per test data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct use in 3.3V, 5V, and 9V battery systems without regulation. |
| On-Resistance (RON) | 20Ω max at +5V, 10Ω max at +12V - ensures minimal signal attenuation and THD degradation in audio paths. |
| Off-Leakage Current | 1nA max at +25°C, 20nA max at +85°C - preserves accuracy in high-impedance sensor front-ends and sample-hold circuits. |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports multiplexing of signals up to ~2MHz without significant settling delay. |
| Charge Injection | 10pC max - limits voltage glitch on capacitive loads (e.g., ADC inputs) during switching transitions. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows unattenuated passage of full-scale signals in both directions (bidirectional). |
| Logic Compatibility | 0.8V–2.4V input thresholds at +5V supply - interoperable with 5V TTL and CMOS logic without pull-ups or buffers. |
Pinout & Package
MAX4514EPA is housed in an 8-pin plastic DIP package with 0.3-inch body width and through-hole mounting. Pin 1 is COM (common terminal), Pin 2 is NO (normally open), Pin 3 is NC (not internally connected), Pin 4 is V+, Pin 5 is GND, Pin 6 is IN (digital control input), Pin 7 is NC, and Pin 8 is NC. All NC pins must remain unconnected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Analog common node - bidirectional signal path shared between NO and internal switch FET. |
| 2 | NO | Normally open analog terminal - connects to COM only when IN = HIGH; electrically identical to NC in MAX4515. |
| 3, 7, 8 | N.C. | No internal connection - must be left floating or tied to GND for mechanical stability (no electrical function). |
| 4 | V+ | Positive supply for analog and digital circuitry - sets rail-to-rail signal range and powers internal level translators. |
| 5 | GND | Ground reference for analog signals and logic - forms return path for ESD diode leakage and supply current. |
| 6 | IN | Digital control input - HIGH enables COM–NO connection; LOW opens the switch (NO = high-impedance). |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | tON > tOFF at +5V ensures no momentary short between NO and NC paths during state transitions. |
| Guaranteed RON flatness | ≤3Ω over full analog signal range (0V to V+) - maintains consistent gain and linearity in variable-gain stages. |
| Low charge injection | 10pC max - reduces error voltage in sampled-data systems (e.g., driving 1nF load yields ≤10mV glitch). |
| ESD robustness | >2000V per Method 3015.7 - withstands handling and board-level ESD events without latch-up or parametric shift. |
| Temperature-stable leakage | Off-leakage remains ≤20nA up to +85°C - critical for long-duration battery monitoring and medical sensor interfaces. |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514ESA | Same electrical specs, but in 8-pin SO package (surface-mount); thermal resistance differs (471mW vs. 727mW for DIP). | Preferred for space-constrained PCBs requiring reflow assembly; less suitable for prototyping or through-hole test fixtures. | Select MAX4514ESA when automated SMT production is required and thermal margin permits lower power dissipation. |
| ADG1211BRZ | 4-channel SPST, 125Ω RON at +5V, −40°C to +125°C rating, higher leakage (50nA @ +85°C), different pinout. | Used where multi-channel integration reduces component count; unsuitable for ultra-low-leakage or low-RON requirements. | Choose ADG1211BRZ only if channel density outweighs RON and leakage penalties - not a drop-in replacement. |
Compared with MAX4514ESA, MAX4514EPA offers higher power dissipation margin and easier manual soldering, while ADG1211BRZ trades single-channel optimization for quad integration at higher on-resistance and leakage - making MAX4514EPA optimal for precision single-path switching in industrial temperature environments.

FAQ
What is the operating temperature range of the MAX4514EPA?
The MAX4514EPA is rated for operation from -40°C to +85°C, qualifying it for industrial and extended-temperature applications. This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, distinguishing it from the commercial-grade MAX4514CPA (0°C to +70°C) and military-grade MAX4514MJA (-55°C to +125°C).
Does the MAX4514EPA support bidirectional signal flow?
Yes, the MAX4514EPA supports fully bidirectional analog signal routing between its COM and NO terminals. The device has no intrinsic directionality - signals pass with identical on-resistance, capacitance, and leakage characteristics regardless of direction - as explicitly stated in the Pin Description note: "NO, NC, and COM pins are identical and interchangeable. Any may be considered as an input or an output."
Can the MAX4514EPA be used with a 3.3V supply?
Yes, the MAX4514EPA operates reliably from +2V to +12V, including +3.3V. Electrical Characteristics tables confirm RON = 50Ω max and leakage parameters at +3V supply. However, logic thresholds scale with V+: at +3.3V, input high must exceed ~1.3V (not 2.4V), so ensure controller outputs meet this reduced threshold.
What is the maximum analog signal voltage the MAX4514EPA can handle?
The MAX4514EPA supports rail-to-rail analog signals from 0V to V+. With V+ = +5V, the analog range is 0V to +5V; with V+ = +12V, it extends to 0V to +12V. Absolute maximum ratings allow signals up to (V+ + 0.3V) or -0.3V due to internal ESD diodes - exceeding these clamps current and risks damage.
Is the MAX4514EPA pin-compatible with the MAX4515EPA?
No - although both share identical pinouts in the same package (e.g., DIP, SO, SOT23-5), the MAX4514EPA is normally open (NO), while the MAX4515EPA is normally closed (NC). Their functional behavior is complementary, not interchangeable: applying the same logic signal produces opposite switch states, requiring firmware or schematic changes for substitution.
