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 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 - enabling precision signal path control in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4514CSA datasheet, MAX4514CSA pinout, MAX4514CSA application, or MAX4514CSA 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 SOT23-5 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4514CSA implements a CMOS transmission-gate architecture with dual-channel ESD protection diodes tied to V+ and GND on all analog pins. Its digital input stage uses level-shifting circuitry to translate 0.8V–2.4V logic thresholds into full-rail gate drive under +5V supply, ensuring robust switching across temperature.
Signal integrity is maintained via matched P/N transistor sizing that minimizes on-resistance variation over VCOM (±3Ω flatness) and suppresses charge injection (10pC typical). The device exhibits no internal connection between analog paths and supply rails - leakage flows exclusively to V+ or GND, not between NO/NC and COM terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration with Li-ion, 3.3V, and 5V systems without level shifters. |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance measurement circuits (e.g., pH sensors, thermocouples). |
| Charge Injection | 10pC max - limits voltage glitch on capacitive loads (e.g., ADC sample-and-hold inputs) during switching. |
| Switching Speed | tON = 150ns, tOFF = 100ns at +5V - supports multiplexing of audio, video, or serial data up to ~2MHz. |
| Logic Compatibility | 0.8V to 2.4V input thresholds at +5V - interoperates directly with standard TTL and CMOS logic families. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-swing AC/DC signal routing without clipping or headroom loss. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.7mm footprint, 1.1mm height) with exposed pad option for thermal enhancement; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally-open analog terminal | Open-circuit when IN = LOW; connects to COM only when switch is enabled - defines default signal isolation state. |
| 2 - IN | Digital control input | Active-high logic input; drives internal level shifter to fully enhance/deplete CMOS transmission gates. |
| 3 - GND | Analog/digital reference ground | Common return for all analog signals and digital logic; must be low-impedance to minimize noise coupling. |
| 4 - V+ | Positive supply rail | Powers analog switch core and digital interface; sets maximum analog signal swing (0V to V+). |
| 5 - COM | Common analog terminal | Shared node for bidirectional signal flow; connects to NO (MAX4514) or NC (MAX4515) based on control state. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | ≤3Ω variation over full analog range - maintains consistent gain and THD across signal amplitude. |
| Break-before-make timing | tON > tOFF at +5V - prevents momentary shorting between NO and NC paths during state transitions. |
| ESD-protected analog pins | Internal diodes to V+ and GND - withstands >2000V HBM without external clamping components. |
| Low supply current | 1µA max at +25°C - extends battery life in always-on monitoring circuits (e.g., portable medical devices). |
| Temperature-stable leakage | 20nA max off-leakage at +85°C - ensures reliable channel isolation in automotive or industrial ambient conditions. |
Applications
| Portable Audio Routing | Battery-Powered 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 |
|---|---|---|---|
| MAX4514CUK | SOT23-5 vs. SC-70-5 package; identical electrical specs and pinout. | Same functional use; SC-70 offers slightly smaller footprint but lower thermal mass. | Select MAX4514CUK only if board layout requires SC-70-5 mechanical compatibility. |
| MAX4516CPA | Dual-supply ±5V operation; pin-compatible but requires split rails and different logic threshold design. | Used where bipolar signal handling (±2.5V) is required, not unipolar rail-to-rail. | Choose MAX4516CPA only when system already uses dual supplies and needs symmetric analog swing. |
Compared with MAX4514CUK, the MAX4514CSA offers identical performance in a widely adopted SOT23-5 package with superior thermal dissipation; versus MAX4516CPA, it eliminates dual-supply complexity and reduces BOM count for single-rail systems - making MAX4514CSA optimal for cost-sensitive, battery-operated designs.

FAQ
What is the maximum supply voltage rating for the MAX4514CSA?
MAX4514CSA has an absolute maximum V+ rating of +13V, but its specified operational range is +2V to +12V. Operating continuously above +12V risks permanent damage, while operation below +2V may cause undefined switching behavior or increased on-resistance. For reliable long-term use, maintain V+ within the +4.5V to +5.5V window when targeting 20Ω RON performance.
Does the MAX4514CSA support bidirectional signal flow?
Yes, MAX4514CSA supports fully bidirectional analog signal routing between NO and COM terminals. Its CMOS transmission-gate structure imposes no inherent directionality - voltage, current, and frequency response are identical regardless of signal source location. This enables flexible PCB layout where either NO or COM can serve as input or output.
How does temperature affect the on-resistance of the MAX4514CSA?
MAX4514CSA on-resistance increases with temperature: at +5V supply, RON rises from 20Ω (max) at +25°C to approximately 25Ω at +70°C and 30Ω at +85°C. This variation is monotonic and predictable, allowing compensation in precision gain-setting applications via calibration tables or temperature-sensing feedback loops.
Can the MAX4514CSA be used with a +3.3V supply?
Yes, MAX4514CSA is fully specified for +3V to +3.6V operation. At +3.3V, typical on-resistance is 50Ω (max), off-leakage remains ≤1nA at +25°C, and logic thresholds stay compatible with 3.3V CMOS outputs. However, tON/tOFF increase to ~150ns/100ns, and charge injection rises slightly - verify timing margins in high-speed multiplexing applications.
Is the SOT23-5 package of the MAX4514CSA pin-compatible with other Maxim analog switches?
MAX4514CSA in SOT23-5 shares pinout with MAX4515CSA (NC version) and MAX4514CUK (SC-70-5), but is not pin-compatible with MAX4516/MAX4517 (dual-supply variants) or MAX4617 (low-charge-injection variant). Pin 1 = NO, Pin 2 = IN, Pin 3 = GND, Pin 4 = V+, Pin 5 = COM - this mapping is fixed and validated per Maxim's official pin description table.
