Product details
Overview
NTS0102GD-Q100 from NXP Semiconductors is a 2-bit automotive-grade dual-supply voltage-level translating transceiver with auto-direction sensing and open-drain I/O, enabling bidirectional translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)) domains. It features independent A/B port referencing, IOFF partial power-down protection, and supports I²C/SMBus and GPIO interfacing in engine control units and body electronics.
For engineers reviewing the NTS0102GD-Q100 datasheet, NTS0102GD-Q100 pinout, NTS0102GD-Q100 application, or NTS0102GD-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40 °C to +125 °C), 50 Mbit/s push-pull data rate, IOFF-enabled power-down safety, and XSON8 package compatibility with space-constrained automotive PCBs.
Technical Context
The NTS0102GD-Q100 implements a switch-type architecture using pass-gate transistors and output edge-rate accelerators-no external direction control signal required. Each channel includes internal 10 kΩ pull-up resistors referenced to respective supply rails (VCC(A) for A1/A2, VCC(B) for B1/B2).
Its auto-direction sensing relies on one-shot circuits triggered at ~VCCI/2, providing accelerated rising-edge transitions with ~50–70 Ω effective output drive during pulse duration (~50 ns). The device enforces VCC(A) ≤ VCC(B) during operation but tolerates any power-up sequence without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - powers A-side logic and defines OE input thresholds |
| VCC(B) Range | 2.3 V to 5.5 V - powers B-side logic and sets B-port output voltage compliance |
| Data Rate | 50 Mbit/s - maximum push-pull throughput; open-drain I²C use depends on external pull-up strength |
| IOFF Protection | Active when either supply is at GND - prevents backflow current and enables safe partial power-down |
| Operating Temp | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications |
| ESD Robustness | B-port: >8 kV HBM - withstands handling and system-level ESD events in vehicle assembly |
| Propagation Delay | A↔B: 2.5–7.3 ns - low-latency bidirectional translation critical for real-time sensor bus timing |
Pinout & Package
XSON8 (SOT996-2) package: 3 mm × 2 mm × 0.5 mm, no leads, 8-terminal surface-mount with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | Data I/O (B-side) | Referenced to VCC(B); supports 2.3–5.5 V logic; internal 10 kΩ pull-up to VCC(B) |
| GND | Ground reference | Common 0 V return for both supply domains and ESD discharge path |
| VCC(A) | Supply A | Powers A-side circuitry and OE input; must be ≤ VCC(B) during active operation |
| A2 | Data I/O (A-side) | Referenced to VCC(A); supports 1.65–3.6 V logic; internal 10 kΩ pull-up to VCC(A) |
| B1 | Data I/O (B-side) | Second B-port channel; identical electrical behavior to B2 |
| VCC(B) | Supply B | Powers B-side circuitry and defines B-port output voltage range |
| OE | Output Enable (active HIGH) | Referenced to VCC(A); LOW forces all ports into high-impedance OFF-state |
| A1 | Data I/O (A-side) | Second A-port channel; identical electrical behavior to A2 |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NTS0102TL-Q100H | XSON8 package with center thermal pad (non-electrical); GD has no center pad | Drop-in replacement per NXP Discontinuation Notice 202111012DN; same pinout and electrical specs | Select TL for improved thermal dissipation in high-ambient environments; verify PCB trace clearance under center pad if replacing GD |
| TXS0102QPWRQ1 | Texas Instruments part; supports same voltage ranges but uses different auto-sensing algorithm and lacks IOFF | Not AEC-Q100 Grade 1 qualified; rated only to +105 °C ambient | Use only in non-critical cabin modules where extended temperature range and IOFF are not required |
Compared with NTS0102GD-Q100, the TL-Q100H offers identical functionality with enhanced thermal performance, while the TXS0102QPWRQ1 provides functional overlap but lacks automotive-grade reliability and power-down safety-making NTS0102GD-Q100 the sole choice for engine bay or safety-critical interfaces.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0102GD-Q100?
The NTS0102GD-Q100 requires VCC(A) ≤ VCC(B) during active operation, with VCC(A) ranging from 1.65 V to 3.6 V and VCC(B) from 2.3 V to 5.5 V. The maximum permissible difference is therefore 5.5 V − 1.65 V = 3.85 V, but design practice mandates keeping VCC(A) within 0.3 V below VCC(B) to ensure stable auto-direction sensing and avoid timing skew. This constraint is explicitly defined in Table 6 footnote [2] of the NTS0102GD-Q100 datasheet.
Does the NTS0102GD-Q100 support true bidirectional communication on both A1/A2 and B1/B2 channels simultaneously?
Yes, the NTS0102GD-Q100 supports concurrent bidirectional operation across both channel pairs (A1↔B1 and A2↔B2), enabled by independent auto-direction sensing per channel. Each I/O pair detects local signal transitions and activates the appropriate pass-gate and one-shot accelerator without cross-talk or arbitration delay. This capability is confirmed in Figure 9's architecture diagram and Table 4's function table, which shows simultaneous A→B and B→A data flow under OE = HIGH.
Can the internal 10 kΩ pull-up resistors on the NTS0102GD-Q100 be disabled or overridden during normal operation?
No-the internal 10 kΩ pull-up resistors on both A and B ports are permanently enabled when OE = HIGH and VCC supplies are active. They are only disabled when OE = LOW, placing all I/Os in high-impedance state. To override their effect, external lower-value pull-ups must be added in parallel; however, doing so lowers VOL and increases static current. Section 13.7 of the NTS0102GD-Q100 datasheet explicitly states these resistors cannot be disabled via configuration or control pins.
Is the NTS0102GD-Q100 compatible with standard I²C bus speeds including Fast Mode Plus (1 Mbps)?
Yes, the NTS0102GD-Q100 supports I²C Fast Mode Plus (1 Mbps) operation. Its 50 Mbit/s push-pull data rate far exceeds I²C timing requirements, and its open-drain architecture with internal pull-ups matches I²C electrical specifications. Propagation delays (≤7.3 ns) and transition times (≤16.7 ns) ensure setup/hold timing margins are maintained even at 1 Mbps with typical 400 pF bus capacitance, as validated in NXP application note AN11124 for I²C translation.
How does the IOFF circuitry in the NTS0102GD-Q100 protect against back-current during partial power-down?
The IOFF circuitry in the NTS0102GD-Q100 disables all output paths when either VCC(A) or VCC(B) falls to GND, blocking conduction through the pass-gate transistors and isolating the powered domain from the unpowered one. This prevents destructive back-current flow that could damage upstream drivers or corrupt logic states-verified per JESD78B Class II latch-up testing (>100 mA) and specified in Section 1.4 of the NTS0102GD-Q100 datasheet.
