Product details
Overview
NTS0304EUKZ from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in WLCSP12 package, supporting open-drain I²C/SMBus and GPIO interfaces between 0.95 V–3.6 V (A-side) and 1.65 V–5.5 V (B-side) domains. It enables seamless communication between mixed-voltage subsystems such as 1.8 V microcontrollers and 3.3 V sensors without external direction control.
For engineers reviewing the NTS0304EUKZ datasheet, NTS0304EUKZ pinout, NTS0304EUKZ application, or NTS0304EUKZ equivalent, key selection considerations include its auto-direction sensing capability, 20 Mbps push-pull data rate, -40 °C to +125 °C operating range, integrated 10 kΩ pull-ups on both sides, and IEC 61000-4-2 Class 4 (8 kV contact) ESD protection on B-side ports.
Technical Context
The NTS0304EUKZ implements a pass-gate transistor architecture with internal one-shot edge acceleration and slew-rate control to reduce ringing and overshoot during rising-edge transitions. Its gate bias is set ~1 VTH above the lower supply rail, enabling robust translation without external direction signals.
It features independent A- and B-side supply domains with no power-sequencing requirement, automatic high-impedance shutdown when either VCC is at GND, and internal 10 kΩ pull-up resistors on all I/O pins referenced to their respective supplies - eliminating need for external biasing in standard I²C applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 0.95 V to 3.6 V - supports direct interface with ultra-low-voltage logic (e.g., 0.95 V FPGA I/O) and 3.3 V controllers |
| VCC(B) Range | 1.65 V to 5.5 V - compatible with legacy 5 V peripherals, 3.3 V buses, and 2.5 V/1.8 V memory interfaces |
| Data Rate | 20 Mbps (push-pull), 2 Mbps (open-drain) - meets full-speed I²C (1 MHz) and UART timing margins with headroom |
| Operating Temp | -40 °C to +125 °C - qualified for automotive under-hood, industrial motor control, and extended-temperature embedded systems |
| ESD Protection | IEC 61000-4-2 Class 4 (8 kV contact) on B-side - enables direct connection to USB, camera, or display ports without external TVS |
| Propagation Delay | B→A: ≤5.9 ns @ VCC(A)=1.8 V/VCC(B)=3.3 V - ensures sub-10 ns latency critical for real-time sensor fusion and time-sensitive GPIO handshaking |
| Input Tolerance | A/OE: 3.6 V tolerant; B: 5.5 V tolerant - allows safe interfacing with higher-voltage drivers even when local VCC is low |
Pinout & Package
NTS0304EUKZ uses a 12-ball Wafer Level Chip Scale Package (WLCSP12) measuring 1.42 × 1.97 × 0.525 mm with 0.4 mm pitch. Ball layout follows JEDEC MO-220 standard SOT1390-10.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | A-side bidirectional I/O | Referenced to VCC(A); accepts inputs up to 3.6 V; includes internal 10 kΩ pull-up to VCC(A) |
| B1–B4 | B-side bidirectional I/O | Referenced to VCC(B); accepts inputs up to 5.5 V; includes internal 10 kΩ pull-up to VCC(B) |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces all I/O into high-impedance OFF-state; requires pull-down for power-up safety |
| VCC(A) | A-side supply | Power domain for A-port logic and OE input; must be ≤ VCC(B) during operation |
| VCC(B) | B-side supply | Power domain for B-port logic; enables translation to 5 V systems while A-side runs at 1.2 V |
| GND | Ground reference | Common return for both supply domains; required for ESD clamp functionality and signal integrity |
| n.c. | No-connect balls | Balls 6 and 9 are unconnected - no routing or solder mask required on PCB footprint |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external DIR pin or controller GPIO, reducing BOM count and PCB routing complexity in bidirectional bus designs |
| Integrated 10 kΩ pull-ups | Removes requirement for four external pull-up resistors per side in I²C applications, saving board space and assembly cost |
| One-shot edge accelerator | Reduces tTLH by >50% vs. passive translators - achieves <10 ns rise time on 50 pF loads while suppressing ringing |
| No power sequencing | Allows independent ramp-up of VCC(A) and VCC(B); device enters safe high-Z state if either supply drops to GND |
| Wide temperature range | Guaranteed operation from -40 °C to +125 °C junction temperature - validated for engine control units and industrial PLCs |
Applications
| I²C Bus Translation | GPIO Voltage Bridging |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E | TI part with identical 4-bit auto-direction function but only 1.65 V–3.6 V VCC(B) range; lacks 5.5 V tolerance and IEC 61000-4-2 Class 4 ESD | Not suitable for 5 V peripheral interfacing or harsh ESD environments like consumer docking stations | Select NTS0304EUKZ when B-side must support 5 V logic or require system-level ESD certification |
| NTB0104 | NXP's push-pull-only variant with no open-drain mode; higher drive strength but no native I²C compatibility without external pull-ups | Requires external 10 kΩ pull-ups for I²C use; unsuitable for SMBus arbitration or multi-master scenarios | Choose NTS0304EUKZ for true open-drain I²C/SMBus translation; NTB0104 only where push-pull speed and drive are primary |
Compared with TXS0104E and NTB0104, the NTS0304EUKZ uniquely combines 5.5 V B-side tolerance, IEC 61000-4-2 Class 4 ESD, and native open-drain support - making it the only option qualified for automotive infotainment USB-C accessories and industrial SMBus sensor hubs requiring certified ESD immunity.

FAQ
What is the maximum capacitive load the NTS0304EUKZ can drive reliably?
The NTS0304EUKZ supports up to 50 pF total load capacitance with guaranteed timing performance. Its extended one-shot pulse duration (~50 ns) enables stable driving of larger loads than conventional translators, but exceeding 50 pF risks incomplete rail transition within the pulse window - leading to signal integrity issues or retriggering. For >50 pF applications, add series termination or reduce trace length to maintain round-trip delay <50 ns.
Can NTS0304EUKZ be used with 5 V microcontrollers on the A-side?
No - the NTS0304EUKZ specifies VCC(A) range as 0.95 V to 3.6 V only. Applying 5 V to VCC(A) or A-side pins violates absolute maximum ratings (VCC(A) max = +4.6 V, but functional operation ceases above 3.6 V). For 5 V A-side interfaces, use the B-side as the high-voltage domain and connect the 5 V controller to B1–B4 pins instead.
Does NTS0304EUKZ require external pull-up resistors for I²C operation?
No - the NTS0304EUKZ integrates 10 kΩ pull-up resistors to VCC(A) on A1–A4 and to VCC(B) on B1–B4. These meet standard I²C pull-up requirements for 100 kHz and 400 kHz modes. External resistors are only needed if faster rise times or stronger drive (e.g., for >400 kHz Fast-mode Plus) are required.
What happens if VCC(A) exceeds VCC(B) during normal operation?
Per datasheet Section 9, VCC(A) must not exceed VCC(B) during active operation - doing so may cause excessive current flow through internal clamps and degrade reliability. However, during power-up/power-down transients, VCC(A) > VCC(B) is tolerated and causes no damage. The device automatically enters high-impedance shutdown if either supply falls to GND.
How does the auto-direction sensing work in NTS0304EUKZ without a DIR pin?
The NTS0304EUKZ uses internal pass-gate transistor biasing and edge-detection circuitry to sense signal direction dynamically. When a LOW-to-HIGH transition occurs on one side, the one-shot accelerator activates and drives the opposite side - effectively establishing conduction path direction based on real-time edge polarity, eliminating need for external control logic or timing-critical DIR signal assertion.
