Product details
Overview
NTS0102GF,115 from NXP Semiconductors is a 2-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in an XSON8 package (1.35 × 1 × 0.5 mm), supporting VCC(A) = 1.65–3.6 V and VCC(B) = 2.3–5.5 V. It enables I²C/SMBus and open-drain GPIO interfacing between 1.8 V/2.5 V/3.3 V and 5.0 V domains with 50 Mbit/s push-pull data rate and IOFF partial power-down protection.
For engineers reviewing the NTS0102GF,115 datasheet, NTS0102GF,115 pinout, NTS0102GF,115 application, or NTS0102GF,115 equivalent, key selection criteria include its auto-direction sensing capability, open-drain compatibility, –40 °C to +125 °C operating range, 8-pin XSON8 footprint, and absence of external direction control logic.
Technical Context
The NTS0102GF,115 implements a switch-type architecture using pass-gate NMOS transistors with gate bias set ~1 VTH above the low-voltage supply, enabling true bidirectional translation without direction pins. Its output edge-rate accelerator (one-shot circuit) detects input transitions at ~VCCI/2 and temporarily bypasses internal 10 kΩ pull-ups with PMOS drivers to reduce tTLH and tTHL.
Each port includes integrated 10 kΩ pull-up resistors (A to VCC(A), B to VCC(B)), disabled when OE = LOW. The device supports IOFF mode: when either VCC(A) or VCC(B) = GND, outputs enter high-impedance state, preventing backflow current during partial power-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 50 Mbit/s push-pull - supports high-speed I²C Fast-mode Plus and UART interfaces without external timing constraints. |
| VCC(A) range | 1.65 V to 3.6 V - compatible with 1.8 V, 2.5 V, and 3.3 V logic domains as low-side supply. |
| VCC(B) range | 2.3 V to 5.5 V - supports 2.5 V, 3.3 V, and 5.0 V domains as high-side supply; VCC(A) ≤ VCC(B) required in active operation. |
| Operating temperature | –40 °C to +125 °C - qualified for automotive under-hood and industrial control applications requiring extended thermal margin. |
| ESD rating (B port) | HBM Class 3B > 8000 V - robust against handling and system-level ESD events on 5 V-tolerant I/Os. |
| IOFF leakage | ±1 μA max at 25 °C - ensures minimal current flow during power-down, critical for battery-backed systems. |
| Propagation delay (A→B) | ≤ 7.3 ns at –40 °C to +125 °C, VCC(A)=1.8 V, VCC(B)=5.0 V - enables sub-10 ns timing-critical level-shifting in real-time control loops. |
Pinout & Package
NTS0102GF,115 is housed in an XSON8 package (SOT1089) measuring 1.35 mm × 1.0 mm × 0.5 mm with no leads and 8 terminals. Pin 1 index area is marked on top surface; thermal pad is absent (unlike TL variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Data I/O referenced to VCC(A) | Bidirectional signals tied to low-voltage domain; internally pulled up to VCC(A) via 10 kΩ resistors. |
| B1, B2 | Data I/O referenced to VCC(B) | Bidirectional signals tied to high-voltage domain; internally pulled up to VCC(B) via 10 kΩ resistors. |
| OE | Output enable (active HIGH, referenced to VCC(A)) | Drives all I/Os into high-impedance OFF-state when LOW; requires pull-down resistor for safe power-up. |
| VCC(A) | Low-side supply voltage | Must be ≤ VCC(B); powers A-port logic and internal bias circuits; supports 1.65–3.6 V. |
| VCC(B) | High-side supply voltage | Powers B-port logic and output acceleration circuitry; supports 2.3–5.5 V. |
| GND | Ground reference (0 V) | Common return path for both supplies; must be connected to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals or microcontroller GPIO overhead in bidirectional protocols like I²C. |
| Integrated pull-up resistors | 10 kΩ per I/O (A to VCC(A), B to VCC(B)) - reduces BOM count and PCB space vs discrete pull-ups; disabled when OE = LOW. |
| IOFF partial power-down | Prevents damaging backflow current when either supply is off - essential for hot-swap and multi-rail power sequencing. |
| 5.5 V-tolerant inputs | A-port inputs accept up to 5.5 V regardless of VCC(A) - allows direct connection to 5 V peripherals even when VCC(A) = 1.8 V. |
| Low dynamic power | ICC(A) + ICC(B) ≤ 30 μA at +125 °C - minimizes quiescent current in always-on sensor nodes and IoT edge devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DRMR | TI part uses different auto-sensing algorithm; higher typical tPHL (12 ns vs 7.3 ns); no IOFF support. | Lacks partial power-down protection - unsuitable for systems requiring hot-swap or independent rail shutdown. | Select NTS0102GF,115 when IOFF and <10 ns propagation are mandatory; TXS0102DRMR only if cost sensitivity outweighs reliability requirements. |
| PCA9306DCUR | Requires external direction pin; no integrated pull-ups; supports only 1.2–3.6 V on both sides (no 5 V tolerance). | Cannot translate to 5 V domains; adds GPIO overhead and PCB routing complexity for direction control. | Choose NTS0102GF,115 for 5 V-tolerant, pin-count-constrained designs; PCA9306DCUR only for legacy 3.3 V ↔ 1.8 V-only systems with available direction control lines. |
Compared with TXS0102DRMR and PCA9306DCUR, the NTS0102GF,115 delivers superior thermal robustness (–40 °C to +125 °C), integrated 5 V-tolerant pull-ups, and guaranteed IOFF protection - making it the preferred choice for automotive, industrial, and high-reliability embedded applications where supply sequencing and ESD immunity are critical.

FAQ
What is the maximum capacitive load supported by NTS0102GF,115?
The NTS0102GF,115 supports up to 15 pF total lumped capacitance per I/O line, as validated in the datasheet test conditions. Exceeding this value risks incomplete rising-edge acceleration due to one-shot pulse duration limits (~50 ns). For reliable operation, keep PCB trace lengths short, avoid stubs, and use low-capacitance connectors - especially critical in 50 Mbit/s push-pull mode where tTLH degrades with load.
Can NTS0102GF,115 translate between 5.0 V and 1.2 V logic levels?
No. The NTS0102GF,115 requires VCC(A) ≥ 1.65 V and VCC(B) ≥ 2.3 V per datasheet specifications. A 1.2 V supply falls below the minimum VCC(A) rating and will not power the internal bias circuitry correctly. For 1.2 V ↔ 5.0 V translation, consider NXP's NTS0104 or alternative families explicitly rated for sub-1.65 V operation.
Is the thermal pad on NTS0102GF,115 electrically connected?
No. The NTS0102GF,115 uses the SOT1089 package (XSON8, 1.35 × 1 × 0.5 mm), which has no thermal pad. This distinguishes it from the NTS0102TL (SOT1052-2), which includes an unconnected center pad. PCB layout for NTS0102GF,115 requires only the 8 peripheral terminals - no thermal pad soldering or grounding is needed or possible.
Does NTS0102GF,115 require external pull-up resistors for I²C operation?
No. The NTS0102GF,115 integrates 10 kΩ pull-up resistors on both A and B ports (to their respective VCC rails), satisfying standard I²C bus requirements for 100 kHz and 400 kHz modes. External pull-ups are unnecessary unless faster rise times or stronger drive strength are required - in which case parallel external resistors may be added, noting that VOL will increase accordingly.
What happens to NTS0102GF,115 outputs when OE is left floating?
Leaving OE floating is not recommended. The OE input is referenced to VCC(A) and has no internal pull-up/down. A floating OE may drift to an indeterminate voltage, causing unpredictable output behavior - including unintended high-impedance states or partial conduction. Always tie OE to GND via a pull-down resistor (e.g., 10 kΩ) to ensure defined OFF-state during power-up and idle periods.
