Product details
Overview
NTS0101GW,125 from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing voltage-level translating transceiver in SC-88 (SOT363) package, supporting bidirectional translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)), with 50 Mbps push-pull data rate, IOFF partial power-down protection, and −40 °C to +125 °C operation. It enables I²C/SMBus interconnection between mixed-voltage microcontrollers and peripherals.
For engineers reviewing the NTS0101GW,125 datasheet, NTS0101GW,125 pinout, NTS0101GW,125 application, or NTS0101GW,125 equivalent, key selection factors include its open-drain-compatible auto-direction architecture, guaranteed 50 Mbps performance across full temperature range, IOFF-enabled safe power sequencing, and dual-rail ESD robustness (8 kV HBM on B port).
Technical Context
The NTS0101GW,125 implements a switch-type voltage translator using an N-channel pass-gate transistor (T3) biased ~1 VTH above the lower supply rail, enabling passive bidirectional conduction without external direction control. Its output edge-rate accelerator employs one-shot triggered PMOS drivers (T1/T2) to bypass internal 10 kΩ pull-ups during rising edges, reducing tTLH to ≤7.6 ns (B port, 5 V) while maintaining <50 Ω effective drive impedance during acceleration.
Direction sensing is fully autonomous: signal flow (A→B or B→A) is determined by relative voltage transitions at either port, with no clock or control overhead. The device enters high-impedance OFF-state when OE is LOW, and supports partial power-down via IOFF circuitry that disables outputs and blocks backflow current when either VCC(A) or VCC(B) = 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - powers A-port logic and OE input; sets VIH/VIL thresholds for A/OE pins |
| VCC(B) Range | 2.3 V to 5.5 V - powers B-port logic; must be ≥ VCC(A); defines VOH min (0.67×VCC(B)) |
| Data Rate | 50 Mbps - maximum guaranteed push-pull throughput across −40 °C to +125 °C |
| Propagation Delay | A↔B: 2.4–7.3 ns - worst-case tPHL/tPLH at VCC(A)=3.3 V / VCC(B)=5.0 V / +125 °C |
| ESD Robustness | B port: 8 kV HBM (JESD22-A114E Class 3B); A port: 2.5 kV HBM - enables direct interface to noisy system buses |
| IOFF Leakage | ±12 µA max (−40 °C to +125 °C) - prevents damaging back-current when either supply is off |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments |
Pinout & Package
NTS0101GW,125 uses SC-88 (SOT363) package: 6-pin plastic surface-mount, 2.1 mm × 1.25 mm × 1.1 mm body, gull-wing leads, pin 1 indicator at lower-left corner below marking code "s1".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply for A-side logic | Reference for A port and OE input; must be ≤ VCC(B); powers internal 10 kΩ pull-up to A |
| GND | Common ground reference | 0 V return path for both supplies; required for proper IOFF and ESD clamp operation |
| A | Bidirectional I/O (A side) | Open-drain compatible; referenced to VCC(A); includes internal 10 kΩ pull-up to VCC(A) |
| B | Bidirectional I/O (B side) | Open-drain compatible; referenced to VCC(B); includes internal 10 kΩ pull-up to VCC(B) |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces A/B into high-Z; requires pull-down for safe power-up |
| VCC(B) | Supply for B-side logic | Reference for B port; defines VOH/VOL limits; must be ≥ VCC(A) for reliable translation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external direction-control signals and timing constraints; enables true plug-and-play level translation |
| Edge-rate acceleration | Reduces B-port tTLH to 1.8 ns (min) at 5 V, enabling clean 50 Mbps rise/fall without external active drivers |
| IOFF partial power-down | Blocks >99% of backflow current when either VCC is off, protecting powered subsystems during hot-swap or brownout |
| Dual-rail ESD protection | 8 kV HBM on B port (I²C bus side) and 2.5 kV on A port (MCU side) meets IEC 61000-4-2 Level 4 system requirements |
| Integrated pull-up resistors | 10 kΩ internal pull-ups on both A and B ports eliminate external components for standard I²C/SMBus termination |

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; same 1-bit, dual-supply, auto-direction architecture; VCC(A): 1.2–3.6 V, VCC(B): 1.65–5.5 V; 6-pin X2SON package (1.0 × 1.0 × 0.5 mm) | Wider VCC(A) range enables 1.2 V MCU interfacing; smaller footprint but no SC-88 compatibility | Select TXS0101DCUR for space-constrained designs requiring 1.2 V support; verify PCB layout change for X2SON vs SOT363 |
| PCA9306DCUR | NXP part; 2-bit, dual-supply translator; VCC(A): 1.2–3.6 V, VCC(B): 1.8–5.5 V; includes automatic direction control but no edge acceleration | Supports two channels per package; lacks one-shot driver → slower tTLH (typ. 15 ns at 5 V); rated for 400 kHz I²C only | Select PCA9306DCUR when multi-bit translation is needed and 50 Mbps is not required; retains NXP ecosystem compatibility |
Compared with TXS0101DCUR and PCA9306DCUR, the NTS0101GW,125 delivers superior high-speed performance (50 Mbps vs 400 kHz) and faster edge response due to its one-shot accelerator, while offering proven robustness in automotive-grade thermal and ESD conditions.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0101GW,125?
The NTS0101GW,125 requires VCC(A) ≤ VCC(B) at all times during active operation. While VCC(A) may temporarily exceed VCC(B) during power-up without damage, sustained violation causes undefined translation behavior and potential latch-up. The absolute maximum ratings allow both supplies up to +6.5 V, but functional operation mandates VCC(B) ≥ VCC(A) - e.g., 1.8 V/3.3 V or 2.5 V/5.0 V pairs are valid; 3.3 V/2.5 V is not.
Does the NTS0101GW,125 support push-pull drivers on both A and B ports, or is it limited to open-drain configurations?
The NTS0101GW,125 supports both open-drain and push-pull drivers on A and B ports. Its architecture relies on detecting voltage transitions to determine direction, making it compatible with either topology. However, for push-pull use, NXP recommends the NTB0101 variant - the NTS0101GW,125 remains fully functional with push-pull sources but achieves optimal timing and noise immunity with open-drain drivers typical of I²C/SMBus.
How does the IOFF feature of the NTS0101GW,125 protect downstream circuitry during partial power-down?
The IOFF circuitry in the NTS0101GW,125 actively disables the output stage and isolates the A and B ports when either VCC(A) or VCC(B) drops to GND. This prevents reverse current flow - for example, if VCC(B) remains active while VCC(A) is off, IOFF blocks current from B port into the unpowered A-side logic, limiting leakage to ±12 µA max and avoiding unintended MCU wake-up or latch-up in the powered domain.
Can the NTS0101GW,125 be used without external pull-up resistors in I²C applications?
Yes - the NTS0101GW,125 integrates 10 kΩ pull-up resistors to VCC(A) on the A port and to VCC(B) on the B port. These satisfy standard-mode (100 kHz) and fast-mode (400 kHz) I²C bus requirements when used with typical bus capacitance (<400 pF). For high-speed mode (3.4 MHz) or heavy capacitive loads, external lower-value pull-ups may be added in parallel to reduce rise time, but are not required for baseline operation.
What is the significance of the "125" suffix in the NTS0101GW,125 part number?
The "125" suffix in NTS0101GW,125 denotes the extended temperature grade: −40 °C to +125 °C. This qualifies the device for under-hood automotive, industrial motor drives, and other high-ambient-temperature applications. It is distinct from the commercial-grade NTS0101GW (−40 °C to +85 °C) and reflects additional screening, characterization, and reliability validation across the full extended range.
