Product details
Overview
MAX4515CUK from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), CMOS analog switch optimized for low-voltage, rail-to-rail signal routing. It operates from a single +2V to +12V supply, delivers 10Ω on-resistance at +12V, supports ≤1nA off-leakage at +25°C, and switches in 100ns turn-off time. It is used in battery-powered audio routing and low-voltage data-acquisition systems where minimal signal distortion and ultra-low leakage are critical.
For engineers reviewing the MAX4515CUK datasheet, MAX4515CUK pinout, MAX4515CUK application, or MAX4515CUK equivalent, this page provides verified electrical parameters, SOT23-5 package details, TTL/CMOS logic compatibility at +5V, break-before-make timing behavior, and real-world selection guidance against comparable SPST analog switches.
Technical Context
The MAX4515CUK implements a CMOS transmission-gate architecture with internal level-shifting logic that translates TTL/CMOS input signals into full-rail gate drives for the analog switch. Its NC configuration ensures continuity between COM and NC terminals when the IN control input is low (0V), and opens the path when IN is high (V+).
It features reverse ESD diodes tied between each analog terminal (COM, NC) and both V+ and GND, enabling rail-to-rail analog signal handling but imposing strict supply voltage constraints on external logic interfacing - e.g., +5V logic must not drive the IN pin if V+ is set to +3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - maintains conduction path at power-up or logic-low control. |
| Supply Range | +2V to +12V single supply - supports direct integration into 3.3V, 5V, and 12V systems without level shifters. |
| On-Resistance | 10Ω max at +12V - ensures <0.1% gain error in 1kΩ sensor interfaces and preserves signal integrity in audio paths. |
| Off-Leakage Current | 1nA max at +25°C - enables use in high-impedance pH sensors and precision integrator hold circuits. |
| Turn-Off Time | 100ns max - allows reliable switching in 5MHz sample-and-hold and multiplexed ADC front-ends. |
| Charge Injection | 10pC max - limits voltage glitch to <10mV on 1nF sampling capacitors, critical for 12-bit+ data acquisition. |
| Logic Compatibility | 0.8V–2.4V thresholds at +5V supply - interoperates directly with standard 5V TTL and CMOS outputs. |
Pinout & Package
SOT23-5 package: compact 2.9mm × 1.6mm surface-mount outline with exposed pad option (not electrically connected), rated for 0°C to +70°C operation and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | Analog switch normally closed terminal | Internally connected to COM when IN = low; open-circuited when IN = high. |
| 2 - IN | Digital control input | Active-high logic input; drives internal level shifter to enable/disable switch conduction. |
| 3 - GND | Ground reference | Common return for analog signals and digital logic; ties substrate to 0V. |
| 4 - V+ | Positive supply | Powers analog switch core and logic circuitry; sets upper rail for rail-to-rail signal handling. |
| 5 - COM | Analog switch common terminal | Shared node for bidirectional signal flow; connects to NC when switch is closed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from GND to V+ without clipping - essential for audio line-level and sensor output routing. |
| Break-before-make timing | tON > tOFF at +5V ensures no momentary short between NC and NO paths during state transitions. |
| Low on-resistance flatness | ≤3Ω variation across 0–3.5V COM voltage range - maintains consistent channel gain in variable-amplitude applications. |
| Guaranteed leakage specs | 100% production tested at +85°C for off-leakage - assures reliability in extended-temperature industrial modules. |
| ESD robustness | >2000V per Method 3015.7 - withstands handling and board-level ESD events without parameter shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4515CSA | Same electrical specs; SO-8 package (4.9mm × 6.0mm) vs. SOT23-5 (2.9mm × 1.6mm) | Preferred where board space permits larger footprint and thermal mass improves power dissipation | Select MAX4515CSA for higher-reliability industrial PCBs requiring SO-8 hand-soldering or reflow compatibility. |
| TS5A23157DCUR | Lower RON (0.9Ω @ 3.3V) but higher off-leakage (50nA @ 85°C); supports 1.65V–5.5V supply only | Better for low-voltage portable gear with tight RON budgets, unsuitable for 12V systems or sub-nA leakage needs | Choose TS5A23157DCUR only when operating strictly at 3.3V and leakage <50nA is acceptable. |
Compared with MAX4515CSA, the MAX4515CUK saves >75% board area and suits ultra-compact designs; versus TS5A23157DCUR, it trades lower RON for wider supply range and 50× lower off-leakage at room temperature - making it superior for precision, multi-rail, or battery-life-critical applications.

FAQ
What is the maximum supply voltage rating for the MAX4515CUK?
The MAX4515CUK has an absolute maximum V+ rating of +13V, but its specified operational range is +2V to +12V. Operating continuously at +12.6V is permitted per Electrical Characteristics tables; exceeding +13V risks permanent damage due to internal ESD diode breakdown. Always observe the 0.3V clamp margin relative to GND or V+ on analog pins.
Does the MAX4515CUK support bidirectional signal flow?
Yes, the MAX4515CUK supports fully bidirectional analog signal routing. The COM and NC terminals are interchangeable - either may serve as input or output - because the CMOS transmission gate structure imposes no inherent directionality. This enables flexible PCB layout in audio patch bays and sensor multiplexers where signal path reversal is required.
What is the guaranteed on-resistance flatness for the MAX4515CUK at +5V supply?
At +5V supply, the MAX4515CUK guarantees on-resistance flatness (∆RON) of ≤3Ω over the full 0V to +3.5V analog signal range (VCOM). This specification ensures minimal gain variation across the signal swing - critical for maintaining linearity in audio buffers and precision instrumentation amplifiers.
Can the MAX4515CUK be used with a +3.3V logic supply while V+ is set to +5V?
Yes, the MAX4515CUK accepts logic inputs from +3.3V systems when V+ = +5V, because its input thresholds (0.8V low, 2.4V high) fall within the +3.3V logic high/low window. However, do not apply +3.3V logic to the IN pin if V+ is set below +3.3V - e.g., +3V - as the 0.3V absolute maximum rating margin would be violated, risking latch-up or damage.
Is the SOT23-5 package of the MAX4515CUK lead-free and RoHS compliant?
Yes, the MAX4515CUK in SOT23-5 packaging is lead-free and RoHS compliant per Maxim's standard manufacturing process. The device carries the "CUK" suffix per Ordering Information, which denotes RoHS-compliant, tape-and-reel packaged SOT23-5 units rated for 0°C to +70°C operation - confirmed in the official datasheet revision history and packaging drawings.
