Product details
Overview
NTS0101GM,115 from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing voltage-level translating transceiver with open-drain I/O, supporting bidirectional translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)). It features active HIGH OE control, IOFF partial power-down protection, and operates across −40 °C to +125 °C. It is used in I²C/SMBus interconnects between mixed-voltage microcontrollers and peripherals.
For engineers reviewing the NTS0101GM,115 datasheet, NTS0101GM,115 pinout, NTS0101GM,115 application, or NTS0101GM,115 equivalent, key selection considerations include its auto-direction sensing capability, 50 Mbps push-pull data rate, IOFF-enabled safe power sequencing, ESD robustness (8 kV HBM on B port), and compatibility with 1.8 V/2.5 V/3.3 V/5.0 V node translation.
Technical Context
The NTS0101GM,115 implements a switch-type architecture using an N-channel pass-gate transistor (T3) biased ~1 VTH above the lower supply rail, enabling passive bidirectional conduction without direction-control pins. Its output edge-rate accelerator (one-shot circuit) detects input transitions at ~VCCI/2 and temporarily activates PMOS drivers (T1/T2) to bypass internal 10 kΩ pull-ups, reducing tTLH and tTHL.
It supports true open-drain operation with internal 10 kΩ pull-up resistors on both A and B ports referenced to their respective supplies. The IOFF circuit disables outputs when either VCC(A) or VCC(B) = 0 V, preventing backflow current during partial power-down - critical for hot-swap and battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - enables interface with 1.8 V or 2.5 V logic domains while maintaining compatibility with 3.3 V controllers. |
| VCC(B) Range | 2.3 V to 5.5 V - supports translation to legacy 3.3 V, 5.0 V peripherals and industrial I/O without level-shifter ICs. |
| Max Data Rate | 50 Mbps - sufficient for high-speed I²C Fast-mode Plus (1 Mbps) and UART up to 25 Mbps with proper layout. |
| IOFF Leakage | <±12 µA at −40 °C to +125 °C - ensures negligible current flow during power-down, preserving battery life and system safety. |
| ESD Robustness | HBM 8 kV on B port, 2.5 kV on A port - meets IEC 61000-4-2 Level 4 for system-level surge immunity in industrial environments. |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC applications. |
| Propagation Delay | 2.4 ns to 7.3 ns (A↔B) - low-latency translation preserves timing margins in real-time sensor or actuator interfaces. |
Pinout & Package
XSON6 package (SOT886): plastic extremely thin small outline, no leads, 6-terminal body measuring 1.0 mm × 1.45 mm × 0.5 mm, moisture sensitivity level 1, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply for A-side logic and I/O reference | Must be ≤ VCC(B); powers internal bias circuitry and defines VIH/VIL thresholds for A and OE pins. |
| GND | Common ground reference | Single shared ground plane required; no separate analog/digital GND pins. |
| A | Bidirectional I/O referenced to VCC(A) | Connects to 1.65–3.6 V domain; includes internal 10 kΩ pull-up to VCC(A). |
| B | Bidirectional I/O referenced to VCC(B) | Connects to 2.3–5.5 V domain; includes internal 10 kΩ pull-up to VCC(B); handles up to 5.5 V inputs. |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces A/B into high-impedance state; requires pull-down for power-up safety. |
| VCC(B) | Supply for B-side logic and I/O reference | Defines VOH/VOL levels for B port; must be ≥ VCC(A) during normal operation per datasheet constraint. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals or GPIOs, reducing PCB routing complexity and firmware overhead in bidirectional buses like I²C. |
| IOFF partial power-down | Prevents damaging back-current when one supply is off - essential for modular systems with independent power domains or hot-plug modules. |
| Integrated 10 kΩ pull-ups | Reduces external component count on both sides; pull-ups are disabled when OE = LOW, avoiding contention during disable. |
| Edge-rate acceleration | One-shot circuit cuts tTLH by up to 40% vs. passive resistor-based translators, enabling reliable 50 Mbps operation without external active drivers. |
| Wide VCC(A)/VCC(B) independence | Supports asymmetric supply combinations (e.g., 1.8 V ↔ 5.0 V) without external voltage dividers or additional regulators. |
Applications
| I²C Bus Translation | UART Voltage Interface |

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0101GM,115?
The NTS0101GM,115 requires VCC(A) ≤ VCC(B) during normal operation per datasheet Section 10, Table 6 footnote [2]. While VCC(A) may transiently exceed VCC(B) during power-up without damage, sustained operation outside this constraint risks incorrect biasing of the pass-gate transistor and unreliable translation. For example, 3.3 V on VCC(A) and 2.5 V on VCC(B) violates specification and must be avoided.
Does the NTS0101GM,115 support I²C Fast-mode Plus (1 Mbps) timing requirements?
Yes, the NTS0101GM,115 supports I²C Fast-mode Plus. With propagation delays as low as 2.4 ns (A→B, VCC(A)=3.3 V, VCC(B)=3.3 V) and rise/fall times under 10 ns, it preserves timing margins even with standard 10 kΩ pull-ups. Its auto-direction sensing and open-drain compatibility ensure full protocol compliance without external direction logic or bus arbitration interference.
Can the NTS0101GM,115 be used with push-pull drivers, or is it limited to open-drain applications?
The NTS0101GM,115 is optimized for open-drain interfaces like I²C and SMBus but can interface with push-pull drivers. However, Section 14.1 notes that the NTB0101 may be more suitable for pure push-pull use due to different internal architecture. When using push-pull sources, ensure driver output impedance stays below 50 Ω to meet specified tPHL/tPLH and data rate limits.
How does the IOFF feature of the NTS0101GM,115 protect the system during partial power-down?
The IOFF circuit in the NTS0101GM,115 disables all outputs when either VCC(A) or VCC(B) falls to GND, limiting leakage current to ±12 µA across −40 °C to +125 °C. This prevents backflow current from an active supply domain into a powered-down domain - protecting downstream ICs, preserving battery charge, and meeting IEC 62368-1 safety requirements for fault conditions.
What are the thermal limitations of the NTS0101GM,115 in its XSON6 (SOT886) package?
In the XSON6 (SOT886) package, the NTS0101GM,115 has a total power dissipation limit of 250 mW at Tamb ≤ 118 °C. Above 118 °C, Ptot derates linearly at 7.8 mW/K. At maximum ambient temperature (+125 °C), usable power is reduced to ~244 mW. Layout must ensure adequate copper area and thermal vias beneath the exposed pad (if present) to maintain junction temperature within −40 °C to +150 °C limits.
