Product details
Overview
NTS0101GS,132 from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing voltage-level transceiver with open-drain I/O, enabling bidirectional translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)). It features 6-pin XSON6 (SOT1202) package, IOFF partial power-down protection, and supports 50 Mbps data rate in push-pull mode. It is used in I²C/SMBus level-shifting interfaces where mixed-voltage system interconnect is required.
For engineers reviewing the NTS0101GS,132 datasheet, NTS0101GS,132 pinout, NTS0101GS,132 application, or NTS0101GS,132 equivalent, key selection considerations include its auto-direction sensing capability, dual-rail supply flexibility, IOFF-enabled power-down safety, open-drain output architecture, and compatibility with 1.8 V/2.5 V/3.3 V/5.0 V node translation in space-constrained embedded systems.
Technical Context
The NTS0101GS,132 implements a pass-gate transistor (N-channel) architecture with integrated one-shot edge-rate acceleration to enable fast rising-edge translation without external direction control. Its gate bias is set ~1 VTH above the lower supply rail, allowing seamless bidirectional operation on A and B ports referenced to separate supplies.
It includes internal 10 kΩ pull-up resistors on both A and B ports, supports active HIGH OE control referenced to VCC(A), and enters high-impedance OFF-state when OE is LOW. The device guarantees safe partial power-down via IOFF circuitry that disables outputs and prevents backflow current when either VCC(A) or VCC(B) is at GND.
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 |
| VCC(B) Range | 2.3 V to 5.5 V - supports connection to 3.3 V or 5.0 V buses including SMBus |
| Max Data Rate | 50 Mbps - sufficient for high-speed I²C Fast-mode Plus (1 Mbps) and GPIO burst transfers |
| IOFF Leakage | <±1 µA at −40 °C to +125 °C - ensures negligible current flow during power-down sequencing |
| ESD Robustness | HBM Class 3B (8 kV on B port), Class 2 (2.5 kV on A port) - protects against handling and system-level ESD events |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| Propagation Delay | 2.4 ns to 7.3 ns (A↔B) - low-latency translation critical for timing-sensitive I²C clock stretching |
Pinout & Package
NTS0101GS,132 uses the SOT1202 package: XSON6, extremely thin small outline, no leads, 6-terminal body measuring 1.0 mm × 1.0 mm × 0.35 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply for A-side logic and OE input | Reference for A port I/O and OE threshold; must be ≤ VCC(B) during operation |
| GND | Common ground reference | Shared return path for both supply domains; required for proper IOFF and ESD clamp operation |
| A | Bidirectional I/O referenced to VCC(A) | Connects to low-voltage domain (e.g., 1.8 V microcontroller); includes internal 10 kΩ pull-up to VCC(A) |
| B | Bidirectional I/O referenced to VCC(B) | Connects to high-voltage domain (e.g., 3.3 V sensor bus); includes internal 10 kΩ pull-up to VCC(B) |
| 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 output drive | Reference for B port I/O; determines VOH level and maximum sink current capability |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal or GPIO, reducing PCB routing and firmware overhead |
| IOFF partial power-down | Prevents damaging back-current when either supply is off - essential for hot-swap and multi-rail power sequencing |
| Integrated 10 kΩ pull-ups | Removes need for external pull-up resistors on I²C/SMBus lines, saving board area and BOM count |
| Open-drain compatible | Supports wired-AND bus topologies like I²C without risk of contention or shoot-through current |
| 50 Mbps push-pull data rate | Enables use beyond legacy I²C (400 kHz/1 MHz) into higher-speed GPIO bridging and custom serial protocols |
Applications
| I²C Bus Level Translation | SMBus System Management Interface |
|---|---|
Use Scenario: Interfacing a 1.8 V ARM Cortex-M microcontroller I²C master to a 3.3 V temperature sensor slave on the same bus.

Use Value: Ensures robust communication during brown-out conditions via IOFF and supports full SMBus alert response timing. |
| GPIO Voltage Bridging | Industrial Sensor Interface |
Use Scenario: Extending GPIO signals from a 3.3 V FPGA I/O bank to control 5.0 V relay drivers in PLC modules.

IC Role / Device Role / Timing Role: Low-leakage, high-ESD-tolerance translator ensuring signal integrity in noisy factory environments with wide ambient temperature swings. Use Value: Delivers −40 °C to +125 °C operation and >8 kV HBM protection on B port - critical for field-deployed sensor nodes. |
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 |
|---|---|---|---|
| TXS0101DCUR | TI part with identical 1-bit, auto-direction, open-drain architecture; supports VCCA = 1.2–3.6 V, VCCB = 1.65–5.5 V; slightly higher max propagation delay (9.5 ns vs. 7.3 ns). | Valid for I²C/SMBus but lacks NXP's IOFF-certified partial power-down guarantee under asymmetric supply loss. | Preferred when wider VCCA range (down to 1.2 V) is needed; verify IOFF behavior in target power-loss scenario. |
| PCA9306DP,118 | NXP part with manual direction control (DIR pin); supports same voltage ranges; includes automatic bus hold and stronger ESD (15 kV HBM on B port). | Requires additional GPIO for DIR control; not suitable for fully autonomous bidirectional use cases like I²C clock stretching. | Select when deterministic direction control is preferred or when higher ESD immunity is mandatory over auto-sensing convenience. |
Compared with TXS0101DCUR and PCA9306DP,118, the NTS0101GS,132 uniquely combines guaranteed IOFF power-down safety, true auto-direction operation, and compact 1.0×1.0 mm XSON6 packaging - making it optimal for space-constrained, fail-safe I²C bridging in automotive and industrial designs.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0101GS,132?
The NTS0101GS,132 requires VCC(A) ≤ VCC(B) during normal operation per datasheet Section 10 (Recommended Operating Conditions). While absolute maximum ratings allow both supplies up to +6.5 V, sustained operation with VCC(A) > VCC(B) risks latch-up or undefined behavior. The device is optimized for translation from lower to higher voltage domains - e.g., 1.8 V → 3.3 V - not reverse.
Does the NTS0101GS,132 support I²C Fast-mode Plus (1 Mbps) timing requirements?
Yes. With typical propagation delays as low as 2.4 ns (A→B, VCC(A)=3.3 V, VCC(B)=5.0 V) and 50 Mbps data rate capability, the NTS0101GS,132 comfortably meets I²C Fast-mode Plus timing budgets for tBUF, tF, and tLOW. Its auto-direction sensing preserves clock stretching behavior without added latency from external control logic.
How does the IOFF feature of the NTS0101GS,132 protect the system during partial power-down?
The IOFF circuitry in the NTS0101GS,132 actively disables both A and B I/O paths when either VCC(A) or VCC(B) drops to GND, limiting leakage current to <±1 µA. This prevents back-current flow from a live rail into a powered-down domain - a critical safeguard in multi-supply systems such as automotive ECUs undergoing controlled sleep/wake transitions.
Can the internal 10 kΩ pull-up resistors on the NTS0101GS,132 be disabled or overridden?
No - the internal 10 kΩ pull-ups on both A and B ports are fixed and cannot be disabled. However, they can be effectively overridden by connecting a lower-value external pull-up resistor in parallel. When OE is LOW, the internal pull-ups are automatically disabled, placing both ports in high-impedance state regardless of external resistors.
Is the NTS0101GS,132 pin-compatible with other variants in the NTS0101 family, such as NTS0101GM or NTS0101GF?
Yes - all NTS0101 variants (GW, GM, GF, GS) share identical 6-pin XSON6 pinout and electrical functionality. The NTS0101GS,132 differs only in package dimensions (SOT1202: 1.0 mm × 1.0 mm × 0.35 mm) versus SOT886 (1.45 mm × 1.0 mm) or SOT891 (1.0 mm × 1.0 mm × 0.5 mm), making it the thinnest and most area-efficient option in the family.
