Product details
Overview
MAX4514CSA+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 +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.
For engineers reviewing the MAX4514CSA+T datasheet, MAX4514CSA+T pinout, MAX4514CSA+T application, or MAX4514CSA+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), charge injection (10pC), TTL/CMOS logic compatibility at +5V, and SOT23-5 package suitability for space-constrained portable designs.
Technical Context
The MAX4514CSA+T implements a CMOS transmission-gate architecture with integrated level translators, enabling direct interface to +5V TTL/CMOS logic while operating across +2V–+12V analog supply. Its internal ESD diodes clamp analog pins to V+ and GND, defining absolute maximum signal range as -0.3V to (V+ + 0.3V).
Switch control follows break-before-make timing (tON > tOFF at +5V), ensuring no transient shorting during state transitions. Leakage currents are dominated by reverse-biased ESD diode conduction paths, with off-leakage specified at 1nA (+25°C) and 20nA (+85°C), and on-leakage at 2nA (+25°C) and 40nA (+85°C).
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 - ensures minimal signal attenuation and distortion in audio and sensor signal paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor front-ends and sample-hold circuits. |
| Charge Injection | 10pC max - limits voltage glitch on sampled nodes, critical for precision ADC input multiplexing. |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports fast channel switching in multi-channel DAQ and communication signal routing. |
| Logic Compatibility | 0.8V–2.4V thresholds at +5V - guarantees reliable drive from standard 5V microcontrollers and FPGA I/Os. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full utilization of supply headroom for unipolar and bipolar signal handling. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.7mm footprint, 1.1mm height), rated for 0°C to +70°C operation, with exposed pad not internally connected.
| 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. |
| 2 - IN | Digital control input | Active-high logic input; drives internal level translator to gate CMOS transmission path. |
| 3 - GND | Ground reference | Common return for analog signals and digital logic; ties substrate internally to V+. |
| 4 - V+ | Positive supply | Powers analog switch core and digital interface; sets analog signal ceiling and logic threshold scaling. |
| 5 - COM | Common analog terminal | Shared node for bidirectional signal routing between NO and COM; interchangeable with NO/NC per datasheet note. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | ≤3Ω variation over full analog signal range - maintains consistent gain and THD across 0V–V+ inputs. |
| Break-before-make timing | tON > tOFF at +5V - prevents momentary shorting between channels during multiplexer sequencing. |
| ESD-protected analog terminals | >2000V HBM - eliminates need for external TVS diodes in handheld and field-deployable equipment. |
| Minimal supply current | ≤1µA at +25°C - extends battery life in always-on monitoring nodes and sleep-mode peripherals. |
| 5-pin SOT23-5 footprint | Compatible with standard pick-and-place and reflow processes - reduces PCB area vs. 8-pin SO/DIP alternatives. |

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+T | SOT23-5 package, identical electrical specs, same +2V–+12V operation and 20Ω RON, but rated for 0°C to +70°C (same temp grade as MAX4514CSA+T). | No functional difference; differs only in tape-and-reel packaging configuration (7in vs. 13in reel) and marking code. | Select MAX4514CUK+T for automated assembly requiring different reel size or carrier tape pitch. |
| MAX4516ESA+ | Pin-compatible dual-supply variant (±5V), 25Ω RON at ±5V, higher off-isolation (-90dB), but requires negative rail and lacks single-supply simplicity. | Used where bipolar signal swing exceeds V+–GND range or where dual-rail noise immunity is required (e.g., instrumentation amplifiers). | Choose MAX4516ESA+ only when dual-supply operation is mandatory; otherwise MAX4514CSA+T offers lower system cost and simpler power design. |
Compared with MAX4514CUK+T, MAX4514CSA+T shares identical performance and temperature rating but uses a different tape-and-reel format; versus MAX4516ESA+, MAX4514CSA+T eliminates negative supply dependency and reduces bill-of-materials count, making it optimal for battery-powered and single-rail embedded systems.

FAQ
What is the maximum supply voltage rating for MAX4514CSA+T?
The MAX4514CSA+T has an absolute maximum V+ rating of +13V. However, its specified operational range is +2V to +12V. Operating continuously at +12.6V (upper limit of +12V supply spec) is supported, but exceeding +13V risks permanent damage due to internal ESD diode breakdown. Always maintain at least 0.3V margin below this absolute limit in production designs.
Does MAX4514CSA+T support bidirectional signal flow?
Yes, the MAX4514CSA+T supports fully bidirectional analog signal routing. The NO and COM terminals are electrically symmetric - either may serve as input or output - and the device passes signals equally well in both directions within its rail-to-rail voltage range (0V to V+). This is explicitly confirmed in the Pin Description section of the datasheet.
What is the guaranteed on-resistance for MAX4514CSA+T at +3.3V supply?
At +3.3V supply, the MAX4514CSA+T guarantees an on-resistance (RON) of 50Ω maximum (per Electrical Characteristics table for +3V supply). This is higher than the 20Ω spec at +5V due to reduced gate overdrive, and must be accounted for in low-distortion or low-gain-error designs operating from 3.3V rails.
Can MAX4514CSA+T be used with a +5V logic input while powered from +3V V+?
No - connecting +5V logic signals to the IN pin while V+ = +3V violates the absolute maximum rating of (V+ + 0.3V) = +3.3V on any terminal. This risks damaging internal ESD diodes and degrading long-term reliability. The MAX4514CSA+T requires logic levels compatible with its V+ supply; use level-shifting circuitry if interfacing with higher-voltage controllers.
Is thermal shutdown or overcurrent protection built into MAX4514CSA+T?
No, the MAX4514CSA+T does not include thermal shutdown or overcurrent protection circuitry. It relies on external design safeguards - such as current-limiting resistors in series with analog paths and adherence to absolute maximum ratings (e.g., ±30mA pulsed peak current) - to prevent latch-up or metallization failure. Continuous operation above 571mW dissipation (at +70°C ambient) requires thermal derating per the SOT23-5 package specification.
