Product details
Overview
MAX4515CUK+T 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 +2V to +12V single supply, delivers 10Ω on-resistance at +12V, guarantees 1nA off-leakage at +25°C, and supports TTL/CMOS logic compatibility with +5V supply - ideal for battery-powered audio/video switching and low-voltage data-acquisition systems.
For engineers reviewing the MAX4515CUK+T datasheet, MAX4515CUK+T pinout, MAX4515CUK+T application, or MAX4515CUK+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), break-before-make timing (tON > tOFF), low charge injection (10pC), and SOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MAX4515CUK+T implements a CMOS transmission-gate architecture with internal level translators that convert TTL/CMOS logic inputs into full-rail analog gate drive signals. Its V+ and GND pins power both analog switches and digital control circuitry, with ESD diodes clamping analog terminals to supply rails.
It features break-before-make switching behavior at +5V (tON = 150ns, tOFF = 100ns), rail-to-rail analog signal handling (0V to V+), and leakage currents fully characterized across temperature (1nA @ +25°C, 20nA @ +85°C) - enabling precision signal integrity in low-power, high-isolation applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - conducts when control input is LOW, blocks when HIGH. |
| Supply Range | +2V to +12V single supply - enables direct integration with Li-ion, 3.3V, and 5V systems without level-shifting. |
| On-Resistance | 10Ω max at +12V - 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 sensor front-ends and battery-monitoring circuits. |
| Charge Injection | 10pC max - limits voltage glitch on sampled nodes, critical for ADC sample-and-hold and multiplexer accuracy. |
| Switching Speed | tON = 150ns, tOFF = 100ns at +5V - supports fast channel switching in multi-signal data acquisition and communications routing. |
| Logic Compatibility | 0.8V–2.4V thresholds at +5V - interoperates directly with standard TTL and CMOS outputs without external buffers. |
Pinout & Package
SOT23-5 surface-mount package (3.099mm × 1.499mm × 1.397mm), rated for 0°C to +70°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | No connection | Not internally bonded - must be left floating or grounded per layout best practice; no electrical function. |
| 2 - IN | Digital control input | Active-low logic input: LOW = switch ON (NC closed), HIGH = switch OFF (NC open). |
| 3 - GND | Analog/digital ground reference | Common return for supply, logic, and analog paths; must be low-impedance for leakage and noise control. |
| 4 - V+ | Positive supply rail | Powers analog switch core and logic translators; sets maximum analog signal range (0V to V+). |
| 5 - COM | Analog common terminal | Center node of SPST switch; bidirectional - connects to NC when IN = LOW. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full 0V to V+ signal swing - eliminates clipping in audio, sensor, and DAC output paths. |
| Break-before-make timing | tON > tOFF at +5V prevents momentary shorting during state transitions - essential for safe multiplexing in shared-bus systems. |
| Low on-resistance flatness | ≤3Ω variation over signal range - maintains consistent gain and THD across audio and instrumentation bandwidths. |
| Guaranteed leakage performance | 100% tested at hot temperature, correlated at +25°C - provides design confidence for long-term battery-life and sensor accuracy. |
| SOT23-5 footprint | Compact 5-pin package with standardized EIA-481-1 tape-and-reel - enables automated assembly in space-limited portable electronics. |

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 functionality and pinout; rated for -40°C to +85°C industrial temperature range vs. 0°C to +70°C for MAX4515CUK+T. | Required for automotive cabin modules or outdoor industrial sensors where extended thermal operation is mandatory. | Select MAX4515EUK+T when ambient operating temperature exceeds +70°C or drops below 0°C. |
| TS5A23157DCUR | Lower on-resistance (0.9Ω typ at 3.3V) but higher off-leakage (100nA typ at +25°C); 6-pin SOT-23 package with dual SPDT configuration. | Offers dual-channel routing but requires PCB redesign due to different pin count, layout, and logic polarity (active-HIGH). | Choose TS5A23157DCUR only if dual-channel capability and sub-1Ω RON outweigh need for identical footprint and NC logic behavior. |
Compared with MAX4515EUK+T, the MAX4515CUK+T trades extended temperature range for cost and qualification simplicity in commercial-grade portable devices; versus TS5A23157DCUR, it prioritizes leakage-critical single-channel isolation and drop-in SOT23-5 compatibility over ultra-low RON and multi-channel density.

FAQ
What is the logic polarity of the MAX4515CUK+T control input?
The MAX4515CUK+T features active-low logic control: when the IN pin is driven LOW (≤0.8V), the NC–COM path is closed (ON); when IN is HIGH (≥2.4V at +5V supply), the path opens (OFF). This matches the "normally closed" functional definition and is confirmed in the truth table and pin description sections of the official datasheet.
Does the MAX4515CUK+T support rail-to-rail analog signals?
Yes, the MAX4515CUK+T supports rail-to-rail analog signal operation from 0V to V+. With V+ supplied at +5V, analog signals from 0V to +5V pass unattenuated through the NC–COM path. This capability is explicitly specified in the Absolute Maximum Ratings and Electrical Characteristics tables, and verified in Typical Operating Characteristics plots.
What is the maximum allowable supply voltage for the MAX4515CUK+T?
The absolute maximum V+ rating for the MAX4515CUK+T is +13V, but the recommended operating range is +2V to +12V. Operation above +12V risks permanent damage, and the device is fully characterized only up to +12.6V in electrical testing. Exceeding +13V violates Absolute Maximum Ratings and may trigger internal ESD diode conduction or oxide breakdown.
Can the MAX4515CUK+T be used with a 3.3V logic supply while powered from +5V?
Yes - the MAX4515CUK+T accepts logic inputs from 0.8V to 2.4V at +5V V+, making it compatible with 3.3V CMOS outputs (which typically swing 0V to 3.3V). Since 3.3V exceeds the 2.4V VIH threshold, the input is reliably recognized as HIGH. However, do not apply 3.3V logic to a MAX4515CUK+T powered from +3V - that would violate absolute maximum ratings.
Is the SOT23-5 package of the MAX4515CUK+T lead-free and RoHS compliant?
Yes, the MAX4515CUK+T is manufactured in a lead-free, RoHS-compliant SOT23-5 package. This is confirmed by Maxim's packaging specifications and ordering information, which list the "+T" suffix as denoting tape-and-reel, lead-free, and RoHS-compliant delivery - consistent with industry-standard JEDEC and IPC requirements for commercial-grade components.
