Product details
Overview
MAX4514CUK+TGA5 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-enabling precision signal path control in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4514CUK+TGA5 datasheet, MAX4514CUK+TGA5 pinout, MAX4514CUK+TGA5 application, or MAX4514CUK+TGA5 equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), charge injection (10pC), break-before-make timing behavior, TTL/CMOS logic compatibility at +5V, and SOT23-5 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4514CUK+TGA5 implements a CMOS transmission-gate architecture with dual-MOSFET (N+P) conduction paths, enabling rail-to-rail analog signal handling across its full +2V to +12V supply range. Its digital control input features fixed 0.8V/2.4V logic thresholds-ensuring reliable switching without level-shifting when powered from +5V.
Internal ESD diodes clamp analog pins to V+ and GND, making leakage current highly dependent on signal voltage relative to supply rails. The device exhibits break-before-make operation (tON > tOFF at +5V), preventing momentary shorting during state transitions-a critical requirement in multiplexer and protection-switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply-supports direct integration into 3.3V, 5V, and 9V battery or adapter-powered systems without regulation. |
| On-Resistance (RON) | 20Ω max at +5V-ensures minimal signal attenuation and distortion in audio and sensor signal chains. |
| Off-Leakage Current | 1nA max at +25°C-preserves accuracy in high-impedance measurement nodes (e.g., pH sensors, thermocouple amplifiers). |
| Charge Injection | 10pC-limits voltage glitch on sampled-hold capacitors, critical for ADC front-end integrity. |
| Switching Speed | tON = 150ns, tOFF = 100ns-enables reliable multiplexing up to ~1MHz in data-acquisition sampling control. |
| Logic Compatibility | 0.8V/2.4V thresholds at +5V-directly interfaces with standard TTL and CMOS microcontrollers without external buffers. |
| Analog Signal Range | Rail-to-rail (0V to V+)-allows full-scale signal passage without clipping in unipolar systems. |
Pinout & Package
SOT23-5 surface-mount package (3.099mm × 1.499mm × 1.17mm), lead-free and RoHS-compliant, optimized for high-density portable PCBs.
| 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-used as signal output or isolated node. |
| 2 - IN | Digital control input | Active-HIGH logic input; drives internal gate drivers-requires 0.8V–2.4V valid levels at +5V supply. |
| 3 - GND | Ground reference | Common return for analog signals and digital logic-must be low-impedance to minimize noise coupling into switch path. |
| 4 - V+ | Positive supply | Powers analog transmission gates and logic circuitry; sets upper rail for rail-to-rail signal handling. |
| 5 - COM | Common analog terminal | Shared connection point between NO and NC (not present in MAX4514); bidirectional signal path-functions as input or output. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | ≤3Ω variation over full analog signal range-maintains consistent gain and THD across 0V–5V inputs in audio routing. |
| Break-before-make timing | tON > tOFF at +5V-eliminates transient short-circuits during channel switching in multiplexer applications. |
| Ultra-low off-leakage | 1nA max at +25°C-enables use in femtoampere-level current measurement circuits without guard-ring compensation. |
| Low charge injection | 10pC-reduces settling error in sample-and-hold stages, supporting 12-bit+ ADC resolution without recalibration. |
| Single-supply flexibility | +2V to +12V operation-permits direct interface with Li-ion (3.0–4.2V), USB (5V), and industrial 9–12V rails without LDO overhead. |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |

| PCMCIA Card Signal Switching | Cellular Phone Peripheral Interface |
|
Use Scenario: Isolating legacy RS-232 transceiver signals from a PCMCIA modem card's 5V I/O bus during hot insertion. IC Role / Device Role / Timing Role: Protection switch inserted between UART TX/RX lines and card-edge connector-enabled only after power stabilization and handshaking. Use Value: +2V to +12V supply tolerance accommodates both 3.3V and 5V PCMCIA host buses; break-before-make prevents bus contention during enable transition. |
Use Scenario: Routing stereo headset audio (left/right/ground) between baseband processor and 3.5mm jack in a GSM smartphone. IC Role / Device Role / Timing Role: Dual-path SPST switch (using two MAX4514CUK+TGA5 devices) controlled by PMIC GPIO to mute/unmute during call state changes. Use Value: SOT23-5 footprint saves board area vs. SO-8 alternatives; 150ns switching ensures no audible pop during call connect/disconnect events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CSA+ | SO-8 package (4.9mm × 3.9mm), same electrical specs, -40°C to +85°C temp range | Better thermal dissipation and manual solderability; unsuitable for ultra-compact layouts | Select when board space allows larger footprint and extended temperature operation is required. |
| TMUX1101DBVR | 1.08Ω RON at 3.3V, 1.5pC charge injection, but only +1.08V to +5.5V supply range | Superior performance below 3.3V; cannot operate at 9V/12V rails like MAX4514CUK+TGA5 | Select for low-voltage, high-precision applications where supply is strictly ≤3.3V and sub-2Ω RON is critical. |
Compared with MAX4514CSA+, the MAX4514CUK+TGA5 offers 40% smaller PCB area and lower profile but trades off thermal margin and extended temperature rating. Against TMUX1101DBVR, it provides wider supply flexibility and higher voltage tolerance at the cost of higher on-resistance and charge injection-making it preferable for mixed-rail industrial and portable designs.

FAQ
What is the maximum supply voltage rating for the MAX4514CUK+TGA5?
The MAX4514CUK+TGA5 has an absolute maximum supply voltage of +13V, with recommended continuous operation from +2V to +12V. Operation above +12V risks permanent damage, and the device is fully specified for on-resistance, leakage, and switching speed within the +2V to +12V range. Exceeding +13V violates Absolute Maximum Ratings per the datasheet.
Does the MAX4514CUK+TGA5 support bidirectional signal flow?
Yes, the MAX4514CUK+TGA5 supports fully bidirectional analog signal flow between the COM and NO terminals. Its CMOS transmission-gate structure imposes no inherent directionality-signals pass with identical on-resistance, capacitance, and leakage characteristics regardless of direction, enabling flexible use as either input selector or output isolator in the MAX4514CUK+TGA5 design.
Can the MAX4514CUK+TGA5 be used with a 3.3V logic controller while powered from a 5V supply?
Yes-the MAX4514CUK+TGA5 logic input is TTL/CMOS-compatible at +5V supply, with guaranteed 0.8V low and 2.4V high thresholds. A 3.3V logic controller outputs ≥2.4V for HIGH and ≤0.8V for LOW under standard conditions, satisfying these thresholds directly. No level shifter is needed when interfacing a 3.3V MCU GPIO to the IN pin of the MAX4514CUK+TGA5.
What is the thermal resistance (θJA) of the MAX4514CUK+TGA5 in its SOT23-5 package?
The MAX4514CUK+TGA5 in SOT23-5 has a specified continuous power dissipation of 571mW at +70°C ambient, with a derating factor of 7.1mW/°C above that temperature. From this, θJA is calculated as 140.8°C/W-consistent with typical SOT23-5 thermal performance. This value assumes standard JEDEC 2-layer board layout; actual θJA may improve with copper pour under the exposed pad (if present) or multi-layer thermal vias.
Is the MAX4514CUK+TGA5 pin-compatible with the MAX4515 series?
No-the MAX4514CUK+TGA5 and MAX4515 variants share identical pinout and package (SOT23-5), but differ functionally: MAX4514 is normally open (NO), while MAX4515 is normally closed (NC). Their IN pin logic is inverted in effect-applying HIGH to IN closes the switch in MAX4514CUK+TGA5 but opens it in MAX4515. Direct substitution requires logic inversion in firmware or external gating.
