Product details
Overview
NTS0102GD,125 from NXP Semiconductors is a 2-bit dual-supply voltage translating transceiver with auto-direction sensing and open-drain I/O, enabling bidirectional level translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)). It features independent A/B port referencing, IOFF partial power-down protection, and operates across –40 °C to +125 °C for I²C/SMBus interconnect in mixed-voltage embedded systems.
For engineers reviewing the NTS0102GD,125 datasheet, NTS0102GD,125 pinout, NTS0102GD,125 application, or NTS0102GD,125 equivalent, key selection criteria include its auto-sensing direction control, 50 Mbit/s push-pull data rate, IOFF-enabled safe power sequencing, open-drain compatibility with I²C bus topologies, and XSON8 package footprint with 3 mm × 2 mm body size.
Technical Context
The NTS0102GD,125 implements a switch-type architecture using pass-gate NMOS transistors biased at ~VTH above the lower supply rail, eliminating external direction control. Its internal one-shot edge accelerator detects input transitions at ~VCCI/2 and temporarily enables PMOS bypass transistors to reduce output rise time.
Each channel includes integrated 10 kΩ pull-up resistors (to VCC(A) on A-side, VCC(B) on B-side), active only when OE is HIGH. The device enforces VCC(A) ≤ VCC(B) during operation but tolerates any power-up sequence, and enters high-impedance state if either supply drops to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - powers A-port logic and OE; must be ≤ VCC(B) during active operation |
| VCC(B) Range | 2.3 V to 5.5 V - powers B-port logic; supports direct interface to 2.5 V/3.3 V/5.0 V domains |
| Data Rate | 50 Mbit/s (push-pull) - enables high-speed GPIO and UART bridging without protocol overhead |
| IOFF Leakage | ±1 μA max - prevents damaging backflow current when either supply is powered down |
| Operating Temp | –40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| ESD Robustness | HBM Class 3B (8 kV) on B-port - ensures reliability in handling-sensitive board-level integration |
| Propagation Delay | ≤ 7.3 ns (A↔B, –40 °C to +125 °C) - maintains timing integrity in real-time sensor-to-processor links |
Pinout & Package
XSON8 package (SOT996-2): plastic extremely thin small outline, no leads, 8 terminals, body dimensions 3 mm × 2 mm × 0.5 mm, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 (B2, B1) | Data I/O referenced to VCC(B) | Bidirectional open-drain signals tied to higher-voltage domain; tolerate up to 5.5 V inputs |
| 2 (GND) | Ground reference | Common return path for both supply domains; required for IOFF and ESD clamp functionality |
| 3 (VCC(A)) | Low-side supply | Powers A-port logic and OE input; sets internal gate bias for pass transistor |
| 4, 5 (A2, A1) | Data I/O referenced to VCC(A) | Bidirectional open-drain signals tied to lower-voltage domain (e.g., 1.8 V microcontroller I/O) |
| 6 (OE) | Output enable (active HIGH) | Drives all ports into high-impedance OFF-state when LOW; referenced to VCC(A) |
| 7 (VCC(B)) | High-side supply | Powers B-port logic; determines VOH minimum (≥0.67×VCC(B)) and VOL maximum (≤0.4 V) |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal or GPIO, reducing PCB routing and firmware complexity in bidirectional buses |
| Integrated 10 kΩ pull-ups | Provides DC current sourcing on both A and B ports - removes requirement for external resistors in standard I²C implementations |
| IOFF partial power-down | Disables outputs and blocks back-current when either VCC(A) or VCC(B) is at 0 V - critical for hot-swap and power-gating applications |
| Open-drain compatible | Supports wired-AND topology and multi-master arbitration required by I²C and SMBus protocols without external components |
| Wide voltage translation range | Enables single-device bridging between 1.8 V ↔ 2.5 V, 1.8 V ↔ 3.3 V, and 1.8 V ↔ 5.0 V interfaces - reduces BOM count vs discrete solutions |

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 |
|---|---|---|---|
| NTS0102TLH | Same XSON8 footprint (SOT1052-2) with center thermal pad; pad is non-functional and electrically isolated from die | Drop-in replacement per NXP Discontinuation Notice 202111012DN; identical electrical specs and timing | Select NTS0102TLH for new designs requiring enhanced thermal dissipation; verify absence of traces under GD's center area before migration |
| TXS0102DR | TSSOP8 package (3.0 mm × 4.4 mm); 1.65 V–3.6 V / 2.3 V–5.5 V range; 60 Mbit/s max data rate | Higher pin pitch eases hand-soldering and test probe access; lacks integrated pull-ups - requires external resistors | Choose TXS0102DR when board space allows larger package and design requires margin beyond 50 Mbit/s or simplified layout verification |
Compared with NTS0102GD,125, NTS0102TLH offers identical functionality in a thermally enhanced package, while TXS0102DR trades smaller footprint for easier assembly and higher speed-but adds external component cost and layout overhead.

FAQ
What is the maximum capacitive load the NTS0102GD,125 can drive reliably?
The NTS0102GD,125 relies on an internal one-shot circuit to accelerate rising edges, with a pulse duration of ~50 ns. To ensure the output reaches VCCO within this window and avoid re-triggering, total lumped capacitance-including PCB trace, connector, and load-must remain below 40 pF. For loads exceeding this, external series resistance or reduced trace length is required to maintain signal integrity and timing compliance in I²C or GPIO applications.
Can the NTS0102GD,125 be used with push-pull drivers, or is it limited to open-drain?
The NTS0102GD,125 supports both open-drain and push-pull drivers on either port, though its architecture is optimized for open-drain use cases like I²C. When driven by push-pull sources, the device still performs bidirectional translation, but users must ensure that opposing drivers do not contend-especially during the one-shot acceleration window (~50 ns)-to prevent excessive ICC or timing violations in high-speed UART or GPIO links.
Does the NTS0102GD,125 require external pull-up resistors for I²C operation?
No. The NTS0102GD,125 integrates 10 kΩ pull-up resistors on both A and B ports-to VCC(A) and VCC(B) respectively-making external resistors unnecessary for standard I²C bus operation. These internal pull-ups are automatically disabled when OE is LOW, ensuring clean high-impedance isolation during power-down or bus arbitration phases in the NTS0102GD,125.
What happens if VCC(A) exceeds VCC(B) during normal operation of the NTS0102GD,125?
VCC(A) must not exceed VCC(B) during active operation per datasheet specification. Exceeding this condition risks forward-biasing internal protection diodes and may cause excessive ICC or latch-up. However, during power-up or power-down transients, the NTS0102GD,125 tolerates VCC(A) ≥ VCC(B) without damage-the device simply enters high-impedance mode if either supply falls to GND, ensuring safe sequencing in complex power architectures.
How does the IOFF feature of the NTS0102GD,125 protect downstream circuitry during partial power-down?
The IOFF circuitry in the NTS0102GD,125 actively disables all I/O paths and clamps leakage to ±1 μA maximum when either VCC(A) or VCC(B) is at 0 V. This prevents damaging backflow current from a live supply domain into a powered-down subsystem-critical for hot-swap capability in modular industrial controllers and battery-backed sensor nodes where the NTS0102GD,125 maintains isolation without external MOSFET switches.
