Product details
Overview
MAX4514CPA 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 MAX4514CPA datasheet, MAX4514CPA pinout, MAX4514CPA application, or MAX4514CPA equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), TTL/CMOS logic compatibility at +5V, break-before-make timing behavior, low charge injection (10pC), and DIP-8 package thermal performance (727mW at +70°C).
Technical Context
The MAX4514CPA implements a CMOS transmission-gate architecture with integrated level translators that convert TTL/CMOS logic inputs into full-rail analog gate drive signals. Its internal ESD diodes clamp analog pins to V+ and GND, defining the absolute maximum analog signal range as -0.3V to (V+ + 0.3V).
Switching is controlled by a single digital input (IN) referenced to GND, where HIGH enables conduction between COM and NO terminals. The device exhibits break-before-make behavior (tON > tOFF at +5V), ensuring no momentary short between signal paths during state transitions.
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 level-shifting. |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level sensor or audio paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement circuits and battery-critical standby modes. |
| Charge Injection | 10pC max - limits voltage glitch on capacitive loads (e.g., ADC sample-and-hold inputs) during switching. |
| Turn-On/Off Time | tON = 150ns, tOFF = 100ns - enables reliable operation up to ~1MHz multiplexing rates in data-acquisition front ends. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-swing AC/DC signal routing without clipping across the supply range. |
| Logic Thresholds | 0.8V to 2.4V at +5V - guarantees interoperability with standard TTL and CMOS outputs without external biasing. |
Pinout & Package
MAX4514CPA is housed in an 8-pin plastic DIP package (0°C to +70°C operating range), with 9.09mW/°C derating above +70°C and 727mW maximum continuous power dissipation at +70°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM (Common) | Analog signal path terminal shared between NO and NC; bidirectional, rail-to-rail capable. |
| 2, 3, 5 | N.C. (Not Internally Connected) | No internal bond wire or circuit connection - must be left unconnected or grounded per layout best practice. |
| 4 | V+ | Positive supply for analog and digital sections; powers internal CMOS switches and logic translators. |
| 6 | IN | Digital control input; HIGH enables COM–NO path, LOW opens it; TTL/CMOS compatible at +5V. |
| 7 | GND | Ground reference for analog signals and digital logic; return path for all internal current sources/sinks. |
| 8 | NO (Normally Open) | Analog output terminal connected to COM only when IN = HIGH; electrically identical to NC in MAX4515. |
Key Features
| Feature | Design Value |
|---|---|
| Low On-Resistance Flatness | ≤3Ω variation over full analog signal range - maintains consistent gain and linearity in precision instrumentation. |
| Break-Before-Make Timing | tON > tOFF at +5V - prevents transient short-circuits during channel switching in multi-path signal routing. |
| ESD-Rated Architecture | >2000V per Method 3015.7 - enhances robustness in handheld and field-deployable equipment handling. |
| Single-Supply Simplicity | No dual-supply rails required - eliminates need for negative bias generators or charge pumps in portable designs. |
| Temperature-Stable Leakage | 20nA max off-leakage at +85°C - ensures long-term accuracy retention in industrial temperature environments. |

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 | Same electrical specs, but in 8-pin SO package with 5.88mW/°C derating and 471mW max power at +70°C. | Better suited for space-constrained PCBs requiring surface-mount assembly and higher thermal density. | Select MAX4514CSA when board real estate or automated assembly mandates SO packaging; pinout and logic are identical. |
| MAX4516CPA | Dual-supply variant (±5V) with 35Ω RON, higher off-isolation (-95dB), and different pinout (IN tied to V−, not GND). | Required for bipolar signal systems (e.g., op-amp-based filters) where true dual-rail operation is mandatory. | Choose MAX4516CPA only when dual supplies are available and rail-splitting is impractical; not pin-compatible with MAX4514CPA. |
Compared with MAX4514CSA, MAX4514CPA offers higher power dissipation margin in through-hole layouts but requires larger board area; versus MAX4516CPA, it simplifies supply design in single-rail systems but cannot handle negative analog signals without level shifting.

FAQ
What is the maximum analog signal voltage range supported by the MAX4514CPA?
The MAX4514CPA supports rail-to-rail analog signals from 0V to V+, with absolute maximum ratings limiting any terminal voltage to -0.3V to (V+ + 0.3V). At V+ = +5V, this means analog inputs can swing from 0V to +5V without distortion or damage, and internal ESD diodes clamp excursions beyond those bounds.
Does the MAX4514CPA require dual supplies or negative voltage rails?
No, the MAX4514CPA operates exclusively from a single positive supply (V+) and ground (GND). It does not require dual supplies, negative rails, or charge pumps. Its internal level translators accept standard TTL/CMOS logic inputs and generate full-rail analog gate voltages using only V+ and GND.
How does the MAX4514CPA behave during power-up or brownout conditions?
During power-up or brownout, the MAX4514CPA remains in its default state: the NO switch stays open (non-conducting) until V+ reaches ~1.5V and the internal logic stabilizes. No undefined switching occurs, and the device draws <1µA supply current below 1.2V, minimizing risk of unintended signal coupling.
Can the MAX4514CPA be used to switch bidirectional digital signals like I²C or SPI lines?
No - the MAX4514CPA is specified and characterized only for analog signal switching. Its on-capacitance (30pF), charge injection (10pC), and lack of guaranteed timing for digital edge rates make it unsuitable for reliable I²C or SPI bus isolation or level translation; dedicated digital bus switches should be used instead.
What is the thermal performance limit of the MAX4514CPA in its DIP-8 package?
The MAX4514CPA in 8-pin plastic DIP has a maximum continuous power dissipation of 727mW at +70°C ambient, with a derating factor of 9.09mW/°C above that temperature. At +85°C ambient, usable power drops to 591mW, and operation beyond +100°C ambient is not recommended without forced cooling or derating analysis.
