Product details
Overview
NTS0302JKZ from NXP Semiconductors is a 2-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and open-drain I/O architecture. It enables seamless interfacing between 0.95 V/1.2 V/1.8 V/2.5 V/3.3 V and 5.0 V domains, supports up to 20 Mbps push-pull or 2 Mbps open-drain data rates, and operates across –40 °C to +125 °C for automotive and industrial I²C/SMBus bus extension.
For engineers reviewing the NTS0302JKZ datasheet, NTS0302JKZ pinout, NTS0302JKZ application, or NTS0302JKZ equivalent, this page delivers verified electrical parameters, thermal behavior, real-world timing performance under varying VCC(A)/VCC(B) combinations, and precise guidance on OE-controlled high-impedance state management and one-shot slew-rate control.
Technical Context
The NTS0302JKZ implements a pass-gate transistor architecture with integrated one-shot edge acceleration and slew-rate control. Its auto-direction sensing eliminates external direction-control signals by detecting signal transitions on either A or B port to dynamically enable bidirectional conduction through an N-channel pass gate biased ~1 VTH above the lower supply rail.
Each I/O cell includes internal 10 kΩ pull-up resistors referenced to its respective supply (VCC(A) for A1/A2/OE; VCC(B) for B1/B2), and features rail-to-rail ESD protection per JESD22-A114E (HBM >2000 V) and JESD22-C101E (CDM >1000 V). No power sequencing is required - VCC(A) may ramp before or after VCC(B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 0.95 V to 3.6 V - supports ultra-low-voltage logic (e.g., 0.95 V IoT sensors) while maintaining compatibility with 1.2 V, 1.8 V, and 3.3 V domains. |
| VCC(B) Range | 1.65 V to 5.5 V - enables direct interface to 2.5 V, 3.3 V, and 5.0 V microcontrollers, PMICs, or legacy peripherals without level-shifter cascading. |
| Data Rate (Push-Pull) | 20 Mbps - sufficient for high-speed UART, GPIO burst transfers, and fast-mode-plus I²C (1 Mbps) with margin. |
| Data Rate (Open-Drain) | 2 Mbps - compliant with standard-mode (100 kHz) and fast-mode (400 kHz) I²C/SMBus, including clock stretching. |
| Propagation Delay (B→A) | As low as 1.4 ns at VCC(A)=3.3 V/VCC(B)=5.0 V - ensures minimal latency in time-critical bidirectional control paths. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and harsh-environment embedded systems. |
| ESD Protection | HBM >2000 V (both ports), CDM >1000 V - reduces need for external TVS diodes in space-constrained PCB layouts. |
Pinout & Package
NTS0302JKZ is housed in an X2SON8 (SOT1986-1) package: 1.4 mm × 1.0 mm × 0.32 mm body, no leads, 8-terminal super-thin outline optimized for high-density portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply reference for A-side logic | Must be ≤ VCC(B); powers A1, A2, and OE inputs; sets input thresholds and internal pull-up target. |
| A1, A2 | Bidirectional data I/O (A port) | Referenced to VCC(A); accept up to 3.6 V; include internal 10 kΩ pull-up to VCC(A); support auto-direction sensing. |
| GND | Common ground reference | Single ground connection shared by both supply domains; essential for noise immunity and ESD current return path. |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces all I/Os into high-impedance OFF-state; disable time tdis = 220 ns (max). |
| B2, B1 | Bidirectional data I/O (B port) | Referenced to VCC(B); accept up to 5.5 V; include internal 10 kΩ pull-up to VCC(B); drive strength scales with VCC(B). |
| VCC(B) | Supply reference for B-side logic | Higher-voltage domain supply; must be ≥ VCC(A); defines VOH levels and output drive capability on B port. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external DIR pin and associated routing; detects transition direction dynamically to enable true bidirectional translation without control overhead. |
| Integrated one-shot slew-rate control | Reduces ringing and overshoot on rising edges by accelerating output transitions for ~50 ns, then tapering drive strength to limit EMI. |
| Dual independent pull-ups | 10 kΩ internal pull-ups on both A and B ports eliminate need for external resistors in I²C/SMBus applications, saving board area and BOM cost. |
| No power-sequencing requirement | VCC(A) and VCC(B) may power up in any order; device enters safe power-down mode if either supply drops to GND. |
| Wide temperature operation | Specified from –40 °C to +125 °C with full parameter validation - supports engine control units, battery management systems, and industrial PLCs. |
Applications
| I²C Bus Extension | Multi-Voltage GPIO Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DSGR | 2-bit, dual-supply, auto-direction; VCC(A): 1.2–3.6 V, VCC(B): 1.65–5.5 V; push-pull only; no open-drain mode. | Lacks native open-drain support - requires external pull-ups for I²C; higher ICC(A) at 1.2 V (1.8 μA vs NTS0302JKZ's 0.1 μA). | Select when push-pull-only operation suffices and lowest static current at sub-1.8 V is not critical. |
| PCA9306DCUR | 2-bit, dual-supply, passive FET-based; VCC(A): 1.2–3.6 V, VCC(B): 1.8–5.5 V; no OE pin; no one-shot acceleration. | No enable control or slew-rate management - susceptible to ringing on long traces; limited to ≤1 Mbps I²C due to RC delay. | Select for cost-sensitive, low-speed (<400 kHz) I²C where OE control and EMI reduction are unnecessary. |
Compared with TXS0102DSGR and PCA9306DCUR, the NTS0302JKZ uniquely combines open-drain compatibility, active one-shot edge acceleration, OE-controlled tri-state, and sub-1 V operation - making it the only choice for robust, high-speed, low-voltage I²C/SMBus extension in thermally constrained automotive and portable designs.

FAQ
What is the minimum VCC(A) voltage supported by the NTS0302JKZ?
The NTS0302JKZ supports VCC(A) down to 0.95 V, enabling direct interfacing with next-generation ultra-low-power processors and sensors operating at sub-1 V logic levels - validated across the full –40 °C to +125 °C range with no derating.
Can the NTS0302JKZ be used for I²C communication between 1.8 V and 5.0 V devices?
Yes - the NTS0302JKZ is explicitly designed for I²C/SMBus applications across mismatched voltage domains. With VCC(A) = 1.8 V and VCC(B) = 5.0 V, it maintains 2 Mbps open-drain data rate, meets I²C timing budgets, and provides rail-to-rail ESD protection on both sides.
Does the NTS0302JKZ require external pull-up resistors for I²C operation?
No - the NTS0302JKZ integrates 10 kΩ pull-up resistors on both A and B ports referenced to their respective supplies. These are sufficient for standard-mode (100 kHz) and fast-mode (400 kHz) I²C; external resistors are only needed for faster modes or heavier bus capacitance.
How does the OE pin function on the NTS0302JKZ?
The OE pin is active HIGH and referenced to VCC(A). When OE = LOW, all I/Os enter high-impedance OFF-state within 220 ns (tdis); when OE = HIGH, the one-shot circuit becomes operational after 200 ns (ten), enabling bidirectional translation. Tie OE to GND via pull-down for power-up safety.
What is the maximum capacitive load the NTS0302JKZ can drive reliably?
The NTS0302JKZ reliably drives ≤15 pF total load (including trace and probe capacitance) with full one-shot acceleration. For loads >15 pF, signal integrity degrades due to incomplete rail reach within the 50 ns one-shot pulse - keep PCB traces short and avoid connectors with >2 pF capacitance per pin.
