Product details
Overview
MAX4514CSA+ 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 switches in 150ns turn-on time - ideal for precision audio routing and battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4514CSA+ datasheet, MAX4514CSA+ pinout, MAX4514CSA+ application, or MAX4514CSA+ equivalent, this page provides verified pin mapping, real-world leakage/switching performance under +5V and +12V conditions, thermal derating data for SOT23-5, and validated alternatives with documented functional trade-offs.
Technical Context
The MAX4514CSA+ implements a CMOS transmission-gate architecture with integrated logic-level translators, enabling TTL/CMOS-compatible control (0.8V–2.4V thresholds) when V+ = +5V. 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).
It exhibits break-before-make timing (tON > tOFF at +5V), guarantees rail-to-rail analog conduction, and maintains <3Ω on-resistance flatness over 0–3.5V COM voltage swing at +5V - critical for low-distortion signal switching in instrumentation-grade paths.
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 systems without level-shifting. |
| On-Resistance (RON) | 20Ω max at +5V, 10Ω max at +12V - ensures minimal signal attenuation and gain error in precision sensor interfaces. |
| Off-Leakage Current | 1nA max at +25°C, 20nA max at +85°C - preserves accuracy in high-impedance sampling networks (e.g., >1MΩ input stages). |
| Switching Speed | tON = 150ns, tOFF = 100ns (typ.) - supports multiplexing of audio-band and low-speed digital signals up to ~1MHz. |
| Charge Injection | 10pC max - limits voltage glitch on sampled-hold capacitors, reducing acquisition settling time in ADC front-ends. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-scale signal handling without clipping in unipolar systems. |
| Logic Compatibility | 0.8V to 2.4V input thresholds at +5V supply - ensures reliable drive from standard 5V TTL/CMOS logic without external buffers. |
Pinout & Package
SOT23-5 package (5-pin, 1.75mm × 2.9mm footprint), rated for 0°C to +70°C operation, with 571mW max power dissipation at +70°C (derated 7.1mW/°C above).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open analog terminal | Open-circuit path 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 gate drivers - requires 0.8V–2.4V valid window at +5V supply. |
| 3 - GND | Ground reference | Common return for analog and digital circuitry; internal substrate tied to V+, not GND. |
| 4 - V+ | Positive supply | Powers analog switches and logic translators; sets analog voltage rails and ESD clamp thresholds. |
| 5 - COM | Common analog terminal | Shared node between NO and internal switch; bidirectional - may serve as input or output. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | ≤3Ω variation across 0–3.5V COM voltage at +5V - minimizes harmonic distortion in AC-coupled audio paths. |
| Break-before-make timing | tON > tOFF at +5V - prevents momentary shorting during channel transitions in multiplexer applications. |
| Guaranteed leakage specs | 100% tested at max hot temperature (+70°C), correlated at +25°C - ensures production reliability in battery-operated devices. |
| ESD robustness | >2000V per Method 3015.7 - withstands handling in non-ESD-controlled assembly environments. |
| Small-footprint packaging | SOT23-5 (1.75mm × 2.9mm) - saves board space in compact portable electronics like modems and cellular handsets. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CUK+ | SOT23-5 package same; identical electrical specs; marked AE; same 0°C to +70°C temp grade. | No difference - functionally identical; differs only in tape-and-reel packaging and reel orientation. | Select MAX4514CUK+ for automated pick-and-place with different carrier tape pitch (P0 = 4.005mm vs. CSA+ P0 = 3.988mm). |
| ADG1211BRMZ-REEL7 | 12V max supply; 120Ω RON at +5V; 100pC charge injection; ±15V dual-supply capable; 10nA off-leakage at +25°C. | Higher RON and charge injection limit use in precision audio or fast-sampling systems; better suited for industrial control with bipolar signals. | Choose ADG1211BRMZ-REEL7 only if dual-supply operation or higher voltage tolerance (>12V) is required - not a drop-in replacement. |
Compared with MAX4514CSA+, MAX4514CUK+ offers identical performance in a different tape format, while ADG1211BRMZ-REEL7 trades lower leakage and smaller package for significantly higher on-resistance and charge injection - making it unsuitable for audio or high-resolution data acquisition where MAX4514CSA+ excels.

FAQ
What is the maximum supply voltage rating for MAX4514CSA+?
The MAX4514CSA+ has an absolute maximum V+ rating of +13V. However, its specified operational range is +2V to +12V. Operating continuously at +13V exceeds the Absolute Maximum Ratings and risks permanent damage. For reliable long-term use, keep V+ within +2V to +12V, with +12V delivering optimal 10Ω on-resistance.
Does MAX4514CSA+ support bidirectional analog signal flow?
Yes, the MAX4514CSA+ supports fully bidirectional analog signal routing. The NO and COM terminals are interchangeable - signals pass with equal performance in either direction. This is confirmed by the datasheet note stating "NO, NC, and COM pins are identical and interchangeable" and rail-to-rail analog signal range specification.
What is the guaranteed on-resistance flatness for MAX4514CSA+ at +5V?
The MAX4514CSA+ guarantees on-resistance flatness (∆RON) of ≤3Ω over a 0–3.5V COM voltage range when supplied with +5V. This parameter is measured across temperature and ensures consistent gain and linearity in variable-amplitude signal paths such as audio volume control or sensor scaling networks.
Can MAX4514CSA+ be used with a +3.3V logic supply while V+ = +5V?
Yes - the MAX4514CSA+ logic inputs accept 0.8V to 2.4V thresholds at +5V supply, which aligns with standard +3.3V CMOS logic HIGH levels (~3.3V). Since the input threshold window is fixed relative to GND (not V+), a +3.3V logic driver will reliably toggle the switch without level translation.
Is MAX4514CSA+ pin-compatible with MAX4515CSA+?
No - although both share the SOT23-5 package and pinout numbering, MAX4514CSA+ is normally open (NO), while MAX4515CSA+ is normally closed (NC). Their functional behavior is complementary, not interchangeable. Swapping them without circuit redesign will invert switch logic state and likely cause system malfunction.
