Product details
Overview
The MAX4515CUK-T from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), CMOS analog switch operating from +2V to +12V single supply, with 10Ω on-resistance at +12V, 1nA off-leakage at +25°C, and 100ns turn-off time - used for precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4515CUK-T datasheet, MAX4515CUK-T pinout, MAX4515CUK-T application, or MAX4515CUK-T equivalent, this page delivers verified electrical specs, SOT23-5 package details, break-before-make timing behavior, rail-to-rail analog signal handling, and direct alternatives for low-voltage SPST switching designs.
Technical Context
The MAX4515CUK-T implements a CMOS transmission-gate architecture with internal logic-level translation, enabling TTL/CMOS-compatible control at +5V while supporting rail-to-rail analog signals up to V+. Its digital input thresholds scale with V+ supply voltage, reaching ~3.0V at +12V - maintaining compatibility with CMOS outputs but not standard TTL at higher supplies.
It features internally clamped ESD diodes between each analog terminal and V+/GND, making leakage current highly dependent on analog signal voltage relative to supply rails. Off-isolation degrades with frequency (~−45dB at 10MHz in 50Ω systems), and charge injection is tightly controlled at 10pC, critical for sample-hold and multiplexer accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - conducts when control input is low, opens when high. |
| Supply Range | +2V to +12V single supply - supports wide battery and industrial rail voltages without dual-supply complexity. |
| On-Resistance | 10Ω max at +12V - ensures minimal signal attenuation and distortion in low-impedance audio/data paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor and precision measurement circuits. |
| Turn-Off Time | 100ns max - enables fast channel switching in multi-channel data acquisition and communication routing. |
| Charge Injection | 10pC max - limits voltage glitch on sampled nodes, essential for accurate ADC front-end and sample-hold stages. |

Pinout & Package
SOT23-5 surface-mount package (3.099mm × 1.499mm × 1.17mm), lead-free, RoHS-compliant, rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | No connection | Not internally connected - must be left floating or grounded per layout best practice; no electrical function. |
| 2 - IN | Digital control input | Active-low logic input: low = switch closed (NC path conductive); high = switch open. |
| 3 - GND | Analog/digital ground reference | Common return for supply, logic, and analog paths - requires low-impedance PCB connection to minimize noise coupling. |
| 4 - V+ | Positive supply rail | Single power rail for analog switching core and logic translator - sets analog signal range (0V to V+). |
| 5 - COM | Analog common terminal | Center node of SPST switch - bidirectionally connects to NC terminal when switch is closed. |

| PCMCIA Card Interface | Cellular Phone Baseband Switching |
|
Use Scenario: Isolating legacy parallel ATA signals (IORD#, IOWR#) from host controller during card insertion/ejection sequences. IC Role / Device Role / Timing Role: NC switch placed in series with critical control lines - defaults closed for functional default state, opens only during hot-swap safe mode. Use Value: Break-before-make behavior prevents bus contention; +2V min supply allows operation directly from PCMCIA VCC (3.3V or 5V). |
Use Scenario: Routing microphone bias voltage and receive audio between baseband processor and multiple analog peripherals (earpiece, speaker, headset jack). IC Role / Device Role / Timing Role: Low-noise SPST switch managing analog audio paths with minimal crosstalk and THD degradation. Use Value: −90dB off-isolation at 100kHz suppresses RF coupling; rail-to-rail capability preserves full dynamic range of 2.5Vpp audio signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4515EUK-T | Same silicon, −40°C to +85°C temperature grade vs. 0°C to +70°C for MAX4515CUK-T; identical pinout, RON, leakage, and timing. | Required for automotive cabin modules or industrial controllers needing extended temperature operation. | Select MAX4515EUK-T when ambient operating temperature exceeds +70°C or storage below 0°C is required. |
| ADG821BRMZ-REEL7 | Normally closed SPST switch (Analog Devices); 0.5Ω RON at +5V but limited to +5.5V max supply; 15pC charge injection; 125ns tOFF. | Better RON and lower THD for precision instrumentation, but incompatible with 9–12V battery systems or legacy 5V logic-only designs. | Choose ADG821BRMZ-REEL7 only if supply is strictly ≤5.5V and sub-1Ω on-resistance justifies redesign for tighter gain accuracy. |
Compared with MAX4515CUK-T, MAX4515EUK-T offers identical functionality with extended temperature support, while ADG821BRMZ-REEL7 trades wider supply range and proven hot-swap robustness for lower on-resistance - making MAX4515CUK-T optimal for cost-sensitive, wide-input-voltage portable systems requiring guaranteed 1nA leakage and 100ns switching.

FAQ
What is the maximum supply voltage rating for the MAX4515CUK-T?
The MAX4515CUK-T has an absolute maximum V+ rating of +13V, but its specified operational range is +2V to +12V. Operation above +12V voids parametric guarantees and risks permanent damage due to internal ESD diode conduction. For reliable long-term use, keep V+ ≤ +12V and ensure analog signals remain within GND to V+.
Is the MAX4515CUK-T pin-compatible with the MAX4514CUK-T?
Yes - the MAX4515CUK-T and MAX4514CUK-T share identical SOT23-5 pinout, package dimensions, and electrical interface. The only functional difference is switch state: MAX4515CUK-T is normally closed (NC), while MAX4514CUK-T is normally open (NO). Swapping them requires logic inversion in the control signal to maintain system behavior.
Does the MAX4515CUK-T support bidirectional analog signal flow?
Yes - the MAX4515CUK-T is fully bidirectional: signals pass equally well from COM to NC or NC to COM. This is inherent to its CMOS transmission-gate topology and confirmed in the Pin Description section, which states "NO, NC, and COM pins are identical and interchangeable. Any may be considered as an input or an output."
What is the guaranteed on-resistance flatness for the MAX4515CUK-T at +5V supply?
At +5V supply, the MAX4515CUK-T guarantees on-resistance flatness (∆RON) of ≤3Ω over a 0V to 3.5V analog signal range (VCOM). This tight flatness ensures minimal THD and consistent gain across the signal swing - critical for audio and precision measurement applications.
Can the MAX4515CUK-T be used with a +3.3V supply and +5V logic inputs?
No - connecting +5V logic signals to the IN pin while V+ = +3.3V violates the absolute maximum rating of (V+ + 0.3V) = +3.6V on any terminal. This risks damaging internal protection diodes. Use level-shifting or select a logic-compatible variant like the MAX4515CSA with 5V-tolerant control inputs if interfacing with +5V systems.
