Product details
Overview
P3A9606JK from NXP Semiconductors is a 2-bit dual-supply bidirectional voltage-level translator supporting I3C (12.5 MHz), I2C/SMBus, and SPI protocols across independent 0.72 V–1.98 V supply domains (VCCA ≤ VCCB). It features auto-direction sensing, IOFF partial power-down protection, and operates from –40 °C to +125 °C. It enables interconnection between 0.8 V/1.2 V/1.8 V SoCs and peripherals in mobile sensor hubs and low-power microcontroller systems.
For engineers reviewing the P3A9606JK datasheet, P3A9606JK pinout, P3A9606JK application, or P3A9606JK equivalent, this page delivers verified specifications, validated pin functions, real-world interface use cases for I3C/I2C/SPI level translation, and confirmed alternative parts with documented functional and application differences.
Technical Context
The P3A9606JK uses edge-rate accelerator circuitry and N-channel pass-gate transistors with integrated pull-up resistors to enable directionless, protocol-agnostic bidirectional translation-no external direction control required. Its architecture supports both open-drain (I2C/I3C) and push-pull (SPI) signaling without configuration.
It implements IOFF circuitry that disables outputs and blocks backflow current when either VCCA or VCCB is powered down, ensuring system-level robustness during asymmetric power sequencing. OE is active-HIGH, referenced to VCCA but tolerant to VCCB-level voltages up to 1.98 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| I3C data rate | 12.5 MHz - supports high-speed I3C bus operation including controller/follower roles |
| I2C/SMBus compatibility | Standard-mode (100 kHz), fast-mode (400 kHz), and fast-mode plus (1 MHz) - interoperable with legacy and enhanced I2C systems |
| SPI data rate | Up to 52 Mbit/s - suitable for high-speed SPI peripheral interfacing (e.g., sensors, flash, ADCs) |
| Propagation delay | 0.7 ns (min) to 19.9 ns (max) - ensures timing compliance in sub-100 ns critical paths |
| Operating temperature | –40 °C to +125 °C - qualified for automotive under-hood and industrial embedded applications |
| ESD rating | HBM >2000 V, CDM >1000 V - provides robust handling and board-level reliability in manufacturing and field use |
Pinout & Package
Package: X2SON8 (SOT2015-1), 1.35 mm × 1.0 mm × 0.32 mm body, 0.35 mm pitch, no leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 (B1, B2) | B-side I/O port | Referenced to VCCB; bidirectional data path for 0.72 V–1.98 V domain B (e.g., 1.8 V sensor or memory) |
| 2 | GND | Common reference ground for both supply domains and signal integrity |
| 3 | VCCA | Supply for A-side logic (e.g., 0.8 V/1.2 V SoC core or I/O rail); must be ≤ VCCB |
| 4, 5 (A1, A2) | A-side I/O port | Referenced to VCCA; bidirectional data path for 0.72 V–1.98 V domain A (e.g., 1.2 V MCU) |
| 6 | OE | Active-HIGH output enable; referenced to VCCA but tolerant to VCCB (≤1.98 V); forces high-impedance OFF-state when LOW |
| 7 | VCCB | Supply for B-side logic; must be ≥ VCCA; powers B-port drivers and internal biasing |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NLVSX3308MUTAG | Single-supply (VCC only); supports 1.2 V–3.6 V translation; no IOFF; max I3C rate = 12.5 MHz | Lacks dual-supply flexibility and partial power-down-unsuitable for asymmetric power sequencing or deep-sleep systems | Select when only one supply rail is available and thermal/power constraints permit higher ICC (120 μA typical) |
| TXS0102YZPR | 2-bit, dual-supply; supports I2C/SPI only (no I3C); VCCA/VCCB = 1.2 V–3.6 V; IOFF supported; max SPI rate = 60 Mbit/s | Not I3C-qualified; lacks 12.5 MHz I3C timing compliance and associated slew control for I3C open-drain waveforms | Select for pure I2C/SPI systems needing higher SPI bandwidth and wider voltage range, where I3C is not required |
Compared with NLVSX3308MUTAG and TXS0102YZPR, the P3A9606JK uniquely combines I3C-12.5 MHz support, ultra-low-voltage operation (down to 0.72 V), and robust IOFF behavior-making it the only option qualified for next-generation low-power I3C sensor ecosystems with strict power-domain isolation requirements.

FAQ
What is the maximum supported I3C data rate for P3A9606JK?
The P3A9606JK supports I3C operation up to 12.5 MHz, as specified in the official NXP datasheet Rev. 2.2. This rate is validated across the full operating temperature range (–40 °C to +125 °C) and all supported supply combinations (e.g., VCCA = 1.2 V, VCCB = 1.8 V). The P3A9606JK meets I3C timing requirements including open-drain rise/fall characteristics and bus arbitration latency.
Can P3A9606JK translate between 0.8 V and 1.8 V logic domains?
Yes, the P3A9606JK supports translation between 0.8 V and 1.8 V domains: VCCA can be set to 0.8 V (within 0.72 V–1.98 V range) and VCCB to 1.8 V (with VCCA ≤ VCCB). This configuration is explicitly validated in the datasheet's dynamic characteristics tables and application diagrams (e.g., Figure 5), confirming correct VOL/VOH levels and timing margins.
Does P3A9606JK require external pull-up resistors for I2C operation?
No, the P3A9606JK integrates internal pull-up resistors on both A and B ports to support I2C open-drain operation without external components. These resistors provide DC bias and drive capability per the architecture description in Section 13.2. External pull-ups may still be used for fine-tuning rise time or meeting specific bus capacitance requirements, but they are not mandatory.
What is the recommended power-up sequence for P3A9606JK?
The datasheet specifies turning on VCCB first to its recommended operating voltage (0.72 V–1.98 V), then applying VCCA. This sequence ensures proper internal biasing and avoids undefined states. The P3A9606JK includes power-down protection, but adhering to this order guarantees reliable initialization of the edge-rate accelerator and pass-gate circuitry during startup.
Is OE pin of P3A9606JK compatible with 1.8 V control signals when VCCA = 1.2 V?
Yes-the OE pin is referenced to VCCA but designed to withstand voltages up to VCCB (≤1.98 V). When VCCA = 1.2 V and VCCB = 1.8 V, a 1.8 V control signal applied to OE meets the VIH requirement (≥0.65 × VCCA = 0.78 V) and remains within absolute maximum ratings. This allows direct interfacing with 1.8 V GPIOs without level-shifting the enable signal.
