Product details
Overview
NTS0103GU10,115 from NXP Semiconductors is a 3-bit dual-supply auto-direction-sensing voltage-level translating transceiver with open-drain I/O architecture, supporting bidirectional translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)). It delivers 50 Mbps data rate in push-pull mode, features IOFF partial power-down protection, and operates across −40 °C to +125 °C for industrial and automotive interface bridging.
For engineers reviewing the NTS0103GU10,115 datasheet, NTS0103GU10,115 pinout, NTS0103GU10,115 application, or NTS0103GU10,115 equivalent, this page provides verified electrical parameters, validated XQFN10 package mapping, confirmed I²C/SMBus/UART/GPIO use cases, and two technically documented alternative parts with functional trade-offs.
Technical Context
The NTS0103GU10,115 implements a switch-type voltage translator using N-channel pass-gate transistors and output edge-rate accelerators that detect input transitions at ~VCCI/2 and activate PMOS bypass drivers for <7 ns rise-time enhancement. Its auto-direction sensing eliminates external direction control signals.
Each A-port pin includes an internal 10 kΩ pull-up to VCC(A); each B-port pin includes a 10 kΩ pull-up to VCC(B). The IOFF circuit disables outputs and blocks backflow current when either supply is at GND, enabling safe partial power-down operation without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - Enables direct interfacing with 1.8 V and 2.5 V logic domains while maintaining compatibility with 3.3 V systems. |
| VCC(B) Range | 2.3 V to 5.5 V - Supports translation to legacy 3.3 V, 5.0 V microcontrollers, sensors, and peripherals without level-shifter ICs. |
| Data Rate | 50 Mbps - Sufficient for high-speed I²C Fast-mode Plus (1 Mbps), SMBus 3.0, and UART up to 25 MBd with proper trace layout. |
| IOFF Leakage | ±1 µA max at −40 °C to +125 °C - Ensures negligible current flow during system sleep or supply sequencing, critical for battery-powered designs. |
| ESD Robustness | B port: >8 kV HBM, >8 kV IEC61000-4-2 contact - Protects against handling and system-level ESD events in industrial environments. |
| Propagation Delay | A↔B: 2.4–7.3 ns (−40 °C to +125 °C) - Guarantees timing margin for sub-10 ns clocked interfaces like GPIO-controlled SPI slaves. |
| Operating Temp | −40 °C to +125 °C - Qualified for under-hood automotive, motor control, and industrial PLC applications without derating. |
Pinout & Package
XQFN10 (SOT1160-1) package: 1.40 mm × 1.80 mm × 0.50 mm body, no leads, exposed thermal pad, 10-terminal layout optimized for high-density PCB routing and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC(B) | Supply voltage for B-side I/O | Reference rail for B1–B3 pins; must be ≥ VCC(A) and within 2.3–5.5 V range to enable translation. |
| 2 - VCC(A) | Supply voltage for A-side I/O and OE | Reference rail for A1–A3 and OE; powers internal bias circuits and defines logic thresholds for A port and control inputs. |
| 3–5 - A1, A2, A3 | Bi-directional data I/O (A side) | Open-drain pins referenced to VCC(A); include internal 10 kΩ pull-ups; support auto-direction sensing without external control. |
| 6 - GND | Digital ground reference | Common return path for both supply domains; required for proper IOFF operation and ESD clamp functionality. |
| 7 - OE | Output enable (active HIGH) | When LOW, forces all A/B pins into high-impedance OFF-state; referenced to VCC(A); requires pull-down for power-up safety. |
| 8–10 - B3, B2, B1 | Bi-directional data I/O (B side) | Open-drain pins referenced to VCC(B); include internal 10 kΩ pull-ups; tolerate up to 5.5 V input regardless of VCC(B) setting. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external DIR signal or microcontroller GPIO coordination-reduces BOM count and firmware complexity in multi-voltage I²C buses. |
| Integrated 10 kΩ pull-ups | Reduces external component count on both A and B sides; pull-ups disable automatically when OE = LOW, preventing contention during shutdown. |
| Edge-rate acceleration | One-shot circuit reduces tTLH/tTHL by up to 40% vs passive translators-enables reliable 50 Mbps operation even with 15 pF load and long traces. |
| IOFF partial power-down | Blocks damaging backflow current when either VCC(A) or VCC(B) is off-supports hot-plug, dynamic supply gating, and low-power sleep modes. |
| Wide VCC(A)/VCC(B) independence | Allows asymmetric supply configurations (e.g., VCC(A) = 1.8 V, VCC(B) = 5.0 V) without external regulators or charge pumps-simplifies mixed-voltage board design. |

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 |
|---|---|---|---|
| TXS0103RGTR | TI part uses different edge-acceleration architecture; supports 1.65–3.6 V on both sides; no B-port >5 V tolerance. | Limited to ≤3.6 V on high-side; unsuitable for 5 V peripheral interfacing or legacy industrial modules. | Select NTS0103GU10,115 when translating to 5.0 V domains or requiring >8 kV B-port ESD robustness. |
| PCA9306DCUR | TI part lacks auto-direction sensing; requires external DIR signal; supports only 1.2–3.6 V on low side and 1.8–5.5 V on high side. | Increases GPIO usage and firmware overhead; not drop-in compatible due to extra control pin and different pinout. | Choose NTS0103GU10,115 for simplified I²C/SMBus designs where minimizing control lines and layout space is critical. |

FAQ
What is the maximum capacitive load the NTS0103GU10,115 can drive reliably?
The NTS0103GU10,115 is characterized for loads up to 15 pF with guaranteed timing performance. Heavier loads (>25 pF) risk incomplete rising-edge acceleration due to one-shot pulse duration limits (~50 ns), potentially causing signal integrity issues or re-triggering. For >15 pF, reduce trace length, avoid stubs, and verify tTLH/tTHL margins in system-level testing.
Can NTS0103GU10,115 translate between 1.8 V and 5.0 V without external components?
Yes. The NTS0103GU10,115 supports VCC(A) = 1.8 V and VCC(B) = 5.0 V simultaneously, with internal 10 kΩ pull-ups on both sides and B-port inputs rated to 5.5 V. No external resistors, MOSFETs, or charge pumps are needed-enabling true single-chip bidirectional level translation.
Does NTS0103GU10,115 require specific power-up sequencing?
No. While VCC(A) must never exceed VCC(B) during normal operation, the NTS0103GU10,115 tolerates any power-up order-including VCC(A) ramping before VCC(B). Internal circuitry disables outputs if either supply drops to GND, eliminating sequencing constraints in complex multi-rail systems.
How does the IOFF feature protect the NTS0103GU10,115 during partial power-down?
When either VCC(A) or VCC(B) is at GND, the NTS0103GU10,115's IOFF circuitry forces all I/Os into high-impedance OFF-state and blocks backflow current (<±1 µA). This prevents damage to powered-down sections and avoids bus contention-critical for hot-swap and low-power sleep modes.
Is OE pin active HIGH or active LOW for NTS0103GU10,115?
The OE pin on the NTS0103GU10,115 is active HIGH: a HIGH voltage (≥0.65×VCC(A)) enables bidirectional data flow; a LOW voltage places all A1–A3 and B1–B3 pins in high-impedance OFF-state. A pull-down resistor on OE is recommended to ensure safe default-off behavior at power-up.
