Product details
Overview
The MAX14866UWZ+T from Maxim Integrated is a 16-channel, high-voltage (±110V), analog SPST switch designed for ultrasound transmit/receive multiplexing. It operates from a single +5V low-voltage supply (VCC) and a separate 1.7V–5.5V logic supply (VDD), eliminating dedicated HV supplies. Key confirmed specs include 7Ω typical RON, <100pC charge injection, 50MHz large-signal bandwidth, and 210VPKPK linear input range - enabling high-fidelity beamforming in medical ultrasound probes.
For engineers reviewing the MAX14866UWZ+T datasheet, MAX14866UWZ+T pinout, MAX14866UWZ+T application, or MAX14866UWZ+T equivalent, this page delivers verified electrical parameters, WLP-specific package mapping, SPI timing constraints (30MHz max), SOI-based latchup immunity, and real-world design implications for in-probe integration, relay replacement, and NDT systems.
Technical Context
The MAX14866UWZ+T implements 16 independent SPST switches using latchup-free Silicon-on-Insulator (SOI) process technology, enabling robust operation under ±110V COM/NO voltage stress and transient overshoots common in resonant ultrasound transducer loads. Its analog path supports bipolar HV bursts up to 210VPKPK with flat RON across the full signal range, ensuring harmonic imaging fidelity.
Control is implemented via a 16-bit SPI interface (30MHz max, MSB-first, 16-cycle DOUT delay) with daisy-chain support, plus asynchronous global SET/CLR inputs for bank-level switching. The device features integrated bleed resistors and power-on reset, and requires GND-biasing of COM/NO pins before HV transmission to ensure reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCOM/VNO Rating | ±110V - Enables direct connection to ultrasound transducers without external HV level-shifting or isolation. |
| RON (typ) | 7Ω at 0V - Delivers low insertion loss and minimal signal attenuation in transmit paths. |
| Charge Injection | <100pC - Minimizes DC offset errors and image artifacts during fast switching in pulsed echo systems. |
| Analog Bandwidth | 50MHz (−3dB, large-signal) - Supports wideband harmonic and elastography imaging modes. |
| SPI Clock Max | 30MHz - Allows rapid reconfiguration of all 16 channels within microseconds for dynamic beam steering. |
| Logic Supply Range | VDD = 1.7V to 5.5V - Enables interoperability with 1.8V, 3.3V, or 5V microcontrollers and FPGAs. |
| Off-Isolation | −75dB at 5MHz (TX), −80dB at 5MHz (RX) - Ensures channel crosstalk suppression critical for multi-element array sensitivity. |
Pinout & Package
The MAX14866UWZ+T is packaged in a 110-bump wafer-level package (WLP), measuring 5.53mm × 5.47mm, with an exposed thermal pad (EP) connected to GND. This ultra-compact footprint achieves <1.9mm²/channel density - optimized for space-constrained in-probe electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM0–COM15 | Analog Switch Common Terminal | Connected to ultrasound front-end T/R circuitry; must be driven with HV burst signals (not NO pins). |
| NO0–NO15 | Analog Switch Normally-Open Terminal | Connected to individual transducer elements; carries HV only when switch is ON. |
| VCC | +5V Low-Voltage Analog Supply | Powers internal HV switch core; bypass with ≥0.1µF ceramic capacitor to GND. |
| VDD | +1.7V to +5.5V Logic Supply | Powers digital interface (SPI, SET/CLR); can be tied to VCC if control logic is 5V. |
| DIN / DOUT / CLK / LE | SPI Serial Interface | DIN accepts 16-bit shift register data; DOUT enables daisy-chaining; LE latches data to update switches. |
| SET / CLR | Asynchronous Global Control | SET = high closes all 16 switches; CLR = high opens all - used for bank selection or relay emulation. |
| GND / EP | Ground & Thermal Pad | All GND pins and EP must be solidly connected to system ground plane for EMI control and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Single +5V HV switch operation | Eliminates need for external HV supplies - reduces BOM cost, PCB area, and safety certification burden in probe heads. |
| SOI process technology | Guarantees latchup immunity under ±110V stress and transient overvoltage - critical for ultrasound load resonance events. |
| Flat RON vs. voltage | Maintains linearity across full ±105V analog range - preserves pulse shape integrity for harmonic imaging accuracy. |
| Integrated bleed resistors | Automatically discharges transducer capacitance between pulses - prevents voltage buildup and improves image stability. |
| SPI programming inhibition during TX | Hardware blocks SPI writes for 4.5µs when ±2V TX signal detected - prevents noise-induced misconfiguration during HV burst. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14867UWZ+T | Same pinout and SOI architecture, but supports 32 channels in identical WLP; higher ICC (10.5mA typ) and larger die size. | Better suited for next-gen 32-element arrays; not drop-in compatible due to different shift register depth and timing margins. | Select MAX14867UWZ+T only when channel count expansion is required and board layout accommodates identical footprint with revised SPI framing. |
| ADG5412BRUZ | 4-channel, ±40V-rated, 12Ω RON, no integrated bleed resistors; requires dual ±15V supplies for full rating. | Limited to lower-voltage NDT or lab instrumentation where 210VPKPK linearity and in-probe integration are not required. | Choose ADG5412BRUZ for cost-sensitive, low-channel-count applications with existing ±15V rails and relaxed bandwidth (<20MHz) needs. |
Compared with MAX14867UWZ+T and ADG5412BRUZ, the MAX14866UWZ+T uniquely balances 16-channel density, ±110V capability, single +5V operation, and SOI robustness - making it the only qualified solution for space-constrained, high-fidelity ultrasound probe designs requiring guaranteed 50MHz bandwidth and <100pC charge injection.

FAQ
What is the maximum allowable voltage across COM and NO pins for the MAX14866UWZ+T?
The MAX14866UWZ+T specifies an absolute maximum COM-to-NO voltage of ±110V. This rating applies under both static and dynamic conditions, including HV burst transmission. Exceeding this limit risks permanent damage. For reliable operation, the analog signal must be referenced to GND prior to transmission, and the peak-to-peak voltage must remain within this bound - confirmed in the Absolute Maximum Ratings table on page 1 of the datasheet.
Does the MAX14866UWZ+T require external high-voltage supplies?
No, the MAX14866UWZ+T does not require external high-voltage supplies. It operates from a single +5V low-voltage supply (VCC) for its HV switch core and a separate 1.7V–5.5V logic supply (VDD) for digital control. This architecture eliminates dedicated HV rails - a key enabler for compact, safe, and compliant in-probe ultrasound designs, as explicitly stated in the General Description and Applications sections.
Can the MAX14866UWZ+T be used in daisy-chain configuration?
Yes, the MAX14866UWZ+T supports daisy-chain SPI configuration via its DOUT pin, which outputs shifted data delayed by 16 clock cycles. Multiple devices can be cascaded by connecting each DOUT to the next device's DIN, while sharing CLK, LE, SET, and CLR lines. LE must be pulsed low simultaneously to update all latches - a capability documented in the Functional Diagram and Serial Interface section of the datasheet.
What is the purpose of the integrated bleed resistors in the MAX14866UWZ+T?
The MAX14866UWZ+T integrates bleed resistors to fully discharge transducer capacitance between HV pulses, preventing residual voltage buildup that causes image ghosting or baseline drift. Their value depends on switch state (ON/OFF) and signal amplitude, as detailed in the Electrical Characteristics table and Figure 1. This feature is essential for stable, artifact-free imaging in continuous scanning modes.
How does the MAX14866UWZ+T handle SPI programming during high-voltage transmission?
The MAX14866UWZ+T includes hardware-based SPI programming inhibition: when a ±2V or greater transmit signal is detected on COM/NO pins, all SPI writes are blocked for up to 4.5µs. During this window, the device holds its previous state - preventing noise-induced misconfiguration. This behavior is implemented internally and requires no external circuitry, as described in the "SPI Programming Inhibition During Transmit" section.
