Product details
Overview
NTS0102GT,115 from NXP Semiconductors is a 2-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in XSON8 package, supporting 1.65–3.6 V on side A and 2.3–5.5 V on side B, with open-drain I/O, IOFF partial power-down, and operation up to +125 °C - used for I²C/SMBus level translation between mixed-voltage microcontrollers and peripherals.
For engineers reviewing the NTS0102GT,115 datasheet, NTS0102GT,115 pinout, NTS0102GT,115 application, or NTS0102GT,115 equivalent, key selection considerations include its auto-direction sensing capability, 50 Mbit/s push-pull data rate, IOFF-enabled power-down safety, ESD robustness (8 kV HBM on B port), and compatibility with 1.8 V/3.3 V/5.0 V node interfacing in space-constrained industrial and automotive control systems.
Technical Context
The NTS0102GT,115 implements a switch-type architecture using pass-gate NMOS transistors with gate bias set ~1 VTH above the lower supply rail, enabling true bidirectional translation without direction-control pins. Its internal one-shot edge accelerator detects input transitions at ~VCCI/2 and boosts rising-edge drive for ≤7.6 ns tTLH (B port, 3.3 V).
It features independent A- and B-side supply domains, with OE referenced to VCC(A), IOFF circuitry that disables outputs when either supply is at GND, and integrated 10 kΩ pull-ups per I/O - eliminating external resistors in standard I²C configurations while maintaining VOL ≤ 0.4 V at 1 mA sink current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - supports 1.8 V and 2.5 V logic domains as low-side interface |
| VCC(B) Range | 2.3 V to 5.5 V - enables direct connection to 3.3 V or 5.0 V buses without external regulators |
| Data Rate | 50 Mbit/s (push-pull) - sufficient for high-speed I²C Fast Mode Plus (1 Mbit/s) and UART interfaces |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient environments |
| ESD Robustness | 8 kV HBM (JESD22-A114E Class 3B) on B port - protects against handling and system-level transients |
| IOFF Leakage | ±1 μA max at 25 °C - prevents backflow current during partial power-down of host or peripheral |
| Propagation Delay | ≤5.9 ns (A→B, 1.8 V→3.3 V, –40 °C to +125 °C) - ensures timing compliance in sub-10 ns critical paths |
Pinout & Package
XSON8 package (SOT833-1), plastic extremely thin small outline, no leads, 8 terminals, body size 1 × 1.95 × 0.5 mm, thermal pad optional, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Data I/O (VCC(A)-referenced) | Bidirectional signals tied to 1.65–3.6 V domain; include internal 10 kΩ pull-up to VCC(A) |
| B1, B2 | Data I/O (VCC(B)-referenced) | Bidirectional signals tied to 2.3–5.5 V domain; include internal 10 kΩ pull-up to VCC(B) |
| OE | Output Enable (active HIGH, VCC(A)-referenced) | Drives all I/O into high-impedance state when LOW; requires pull-down for safe power-up |
| VCC(A) | Low-side supply | Must be ≤ VCC(B); powers A-port logic, OE input, and internal bias circuits |
| VCC(B) | High-side supply | Powers B-port logic and output edge accelerator; sets VOH minimum at 0.67×VCC(B) |
| GND | Digital ground reference | Common return for both supply domains; required for proper IOFF and ESD clamp operation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal or GPIO, reducing PCB routing and firmware overhead in bidirectional protocols like I²C |
| Integrated pull-up resistors | 10 kΩ per I/O on both sides - removes four external resistors in standard I²C bus designs, saving board area and BOM cost |
| IOFF partial power-down | Prevents damaging back-current when either VCC(A) or VCC(B) is unpowered - critical for hot-swap and modular subsystems |
| Open-drain compatible | Supports wired-AND topologies and legacy 1-wire/I²C signaling without external FETs or level-shifter ICs |
| Wide temperature range | Specified from –40 °C to +125 °C - meets AEC-Q100 Grade 0 requirements for automotive engine control and ADAS sensor hubs |

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 |
|---|---|---|---|
| TXS0102DSGR | TI part uses different auto-sensing algorithm; higher typical ICC (15 μA vs 14.4 μA max); no IOFF specification | Not qualified for +125 °C operation; rated only to +85 °C - unsuitable for under-hood automotive use | Select NTS0102GT,115 when full automotive temp range, IOFF safety, or 8 kV B-port ESD are required |
| PCA9306DCUR | Requires external direction-control pin; no integrated pull-ups; lower ESD rating (4 kV HBM on B port) | Lacks auto-direction sensing - adds MCU GPIO overhead and timing-critical direction sequencing | Choose NTS0102GT,115 for simplified I²C design with zero-direction-pin implementation and reduced firmware complexity |
Compared with TXS0102DSGR and PCA9306DCUR, the NTS0102GT,115 delivers guaranteed +125 °C operation, IOFF-enabled system-level power-down safety, and superior 8 kV HBM ESD protection on the high-voltage B port - making it the preferred choice for automotive, industrial, and high-reliability embedded applications where thermal margin and fault resilience are critical.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0102GT,115?
The NTS0102GT,115 requires VCC(A) ≤ VCC(B) during normal operation, but permits VCC(A) ≥ VCC(B) during power-up without damage. The absolute maximum ratings allow VCC(A) up to +6.5 V and VCC(B) up to +6.5 V independently, though recommended operation limits VCC(A) to 1.65–3.6 V and VCC(B) to 2.3–5.5 V. Exceeding these ranges risks parametric shift or latch-up.
Does the NTS0102GT,115 require external pull-up resistors for I²C operation?
No, the NTS0102GT,115 includes internal 10 kΩ pull-up resistors on both A1/A2 and B1/B2 pins - fully compliant with standard I²C bus requirements for Fast Mode (400 kbit/s) and Fast Mode Plus (1 Mbit/s). External pull-ups are only needed if faster rise times or lower VOL are required, and must be placed in parallel with the internal resistors.
How does the auto-direction sensing mechanism work in the NTS0102GT,115 without a dedicated DIR pin?
The NTS0102GT,115 uses internal edge-detection circuitry that monitors voltage transitions on both A and B ports. When a falling edge occurs on one side, the pass-gate transistor is enabled to conduct in the opposite direction, and the one-shot accelerator activates to speed up the rising edge. This eliminates the need for external direction control while maintaining deterministic bidirectional behavior for open-drain protocols.
Can the NTS0102GT,115 be used with push-pull drivers, or is it limited to open-drain applications?
The NTS0102GT,115 supports both open-drain and push-pull drivers, but its architecture is optimized for open-drain use cases like I²C. When used with push-pull sources, the device still provides level translation, though the NTB0102 (a related NXP part) is explicitly recommended for push-pull-only applications due to enhanced drive strength and timing characteristics.
What is the thermal performance of the NTS0102GT,115 in the XSON8 (SOT833-1) package at +125 °C ambient?
The NTS0102GT,115 in SOT833-1 has a total power dissipation limit of 250 mW at Tamb ≤ +118 °C, derating linearly by 7.8 mW/K above that temperature. At +125 °C ambient, Ptot is reduced to 244.6 mW. With typical ICC < 30 μA, self-heating is negligible, allowing full functionality within its specified –40 °C to +125 °C operating range without forced cooling.
