Product details
Overview
NTS0104PW-Q100 from NXP Semiconductors is an automotive-qualified 4-bit dual-supply translating transceiver with auto-direction sensing and open-drain I/O architecture, enabling bidirectional level translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)). It supports I²C/SMBus and UART interfaces, features IOFF partial power-down protection, and operates across −40 °C to +125 °C.
For engineers reviewing the NTS0104PW-Q100 datasheet, NTS0104PW-Q100 pinout, NTS0104PW-Q100 application, or NTS0104PW-Q100 equivalent, this page delivers verified electrical parameters, TSSOP14 package details, AEC-Q100 Grade 1 qualification status, and real-world use cases in automotive body control modules, infotainment gateways, and sensor interface subsystems.
Technical Context
The NTS0104PW-Q100 implements a switch-type voltage translator architecture using pass-gate NMOS transistors and edge-rate acceleration circuitry-no external direction control signal required. Its auto-sensing logic detects data flow direction dynamically by monitoring voltage transitions on either port.
Each I/O channel includes internal 10 kΩ pull-up resistors referenced to its respective supply (VCC(A) for A-side, VCC(B) for B-side), and the OE input is referenced solely to VCC(A). The device enters high-impedance OFF-state when OE is LOW, and IOFF circuitry prevents backflow current during partial power-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range VCC(A) | 1.65 V to 3.6 V - enables interfacing with 1.8 V/2.5 V/3.3 V logic domains |
| Supply Range VCC(B) | 2.3 V to 5.5 V - supports 2.5 V/3.3 V/5.0 V systems including legacy automotive microcontrollers |
| Max Data Rate | 50 Mbps - sufficient for high-speed I²C Fast Mode Plus (1 Mbps) and UART up to 25 Mbps |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications |
| IOFF Leakage Current | ±1 µA max - ensures safe isolation during power sequencing without damaging backflow |
| ESD Robustness (B port) | 15 kV HBM - protects against electrostatic discharge in manufacturing and field service environments |
| Propagation Delay (A→B) | 2.4 ns min @ VCC(A)=3.3 V, VCC(B)=5.0 V - enables low-latency communication in time-critical subsystems |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14-lead, 4.4 mm body width, 0.65 mm pitch, exposed pad not electrically connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Low-voltage supply rail (1.65–3.6 V); powers A-side logic and OE input |
| 2–5 | A1–A4 | Bi-directional I/O pins referenced to VCC(A); include internal 10 kΩ pull-up to VCC(A) |
| 6, 9 | n.c. | No-connect pins - must remain unconnected per datasheet |
| 7 | GND | Common ground reference for both supply domains |
| 8 | OE | Active-HIGH output enable referenced to VCC(A); LOW forces all I/O into high-Z state |
| 10–13 | B1–B4 | Bi-directional I/O pins referenced to VCC(B); include internal 10 kΩ pull-up to VCC(B) |
| 14 | VCC(B) | High-voltage supply rail (2.3–5.5 V); powers B-side logic and output drivers |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals in I²C/SMBus systems, reducing PCB routing complexity |
| Integrated 10 kΩ pull-ups | Reduces external component count on both A and B sides - no external resistors needed for basic I²C operation |
| IOFF partial power-down | Prevents current backflow when either VCC(A) or VCC(B) is powered down - critical for mixed-rail power sequencing |
| Open-drain compatible architecture | Supports wired-AND bus topologies and standard I²C pull-up configurations without external level-shifting buffers |
| AEC-Q100 Grade 1 qualification | Validated for automotive applications requiring operation up to +125 °C ambient, including engine control units |

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-Q1 | TI device with identical 4-bit open-drain architecture, but rated only to +85 °C (non-AEC-Q100); lacks IOFF protection | Suitable for industrial or consumer-grade I²C bridges where automotive temperature range and power-down safety are not required | Select NTS0104PW-Q100 when AEC-Q100 Grade 1 qualification, −40 °C to +125 °C operation, or IOFF-backed power sequencing is mandatory |
| PCA9306DCURQ1 | TI 2-bit translator with separate DIR pin; requires external direction control logic and has no auto-sensing capability | Applicable where fixed-direction translation suffices and board space allows additional control routing | Choose NTS0104PW-Q100 to eliminate DIR signal routing, reduce firmware overhead, and support true bidirectional bus arbitration |
Compared with TXS0104E-Q1 and PCA9306DCURQ1, the NTS0104PW-Q100 uniquely combines AEC-Q100 Grade 1 qualification, auto-direction sensing, and IOFF protection in a single 4-bit package-enabling safer, simpler, and more compact automotive I²C/SMBus bridging without compromising thermal or functional safety requirements.

FAQ
What is the maximum capacitive load the NTS0104PW-Q100 can drive reliably?
The NTS0104PW-Q100's one-shot edge accelerator pulse duration (~50 ns) limits reliable operation to ≤50 pF total lumped capacitance (including PCB trace, connector, and load). Exceeding this may prevent outputs from reaching VCCO within the acceleration window, causing signal integrity issues or false ACK/NACK in I²C. Layout best practices include short traces (<2 cm), controlled impedance routing, and avoidance of stubs.
Does the NTS0104PW-Q100 require external pull-up resistors for I²C operation?
No - the NTS0104PW-Q100 integrates 10 kΩ pull-up resistors on all A1–A4 and B1–B4 pins, referenced to VCC(A) and VCC(B) respectively. These satisfy standard-mode I²C (100 kbps) and fast-mode (400 kbps) bus requirements. External resistors are only needed if faster rise times or lower VOL are required, and must be placed in parallel with internal pull-ups.
Can VCC(A) exceed VCC(B) during normal operation of the NTS0104PW-Q100?
No - the datasheet explicitly states "VCC(A) must be less than or equal to VCC(B)" during active operation. Violating this condition risks incorrect pass-gate biasing and unreliable translation. However, during power-up sequencing, either supply may ramp first without damage due to built-in power-down detection circuitry.
How does the NTS0104PW-Q100 handle simultaneous signal transitions on both A and B ports?
The NTS0104PW-Q100 uses per-channel pass-gate transistors and independent one-shot accelerators. Simultaneous transitions do not cause contention because each channel operates autonomously. However, the datasheet advises waiting ~50 ns after one-shot deactivation before reversing direction on the same channel to avoid dynamic ICC spikes and ensure clean switching.
Is the NTS0104PW-Q100 pin-compatible with other members of the NTS0104-Q100 family?
Yes - the NTS0104PW-Q100 (TSSOP14), NTS0104BQ-Q100 (DHVQFN14), and NTS0104UK-Q100 (WLCSP12) share identical pin functions and electrical specifications. Pin mapping differs across packages, but logic behavior, supply ranges, timing, and thermal specs are fully aligned per the common datasheet Rev. 2.
