Product details
Overview
NTS0101GW125 from NXP Semiconductors is a 1-bit dual-supply translating transceiver with auto-direction sensing and open-drain I/O, enabling bidirectional level 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 supports I²C/SMBus, UART, and GPIO interfaces in mixed-voltage systems.
For engineers reviewing the NTS0101GW125 datasheet, NTS0101GW125 pinout, NTS0101GW125 application, or NTS0101GW125 equivalent, key selection considerations include its 50 Mbps push-pull data rate, ±8 kV HBM ESD rating on B port, -40 °C to +125 °C operating range, SC-88 (SOT363) package, and auto-sensing directionality without external control signals.
Technical Context
The NTS0101GW125 implements a switch-type architecture using an N-channel pass-gate transistor and output edge-rate accelerators that detect input transitions at ~VCCI/2 and activate PMOS drivers for ~50 ns to reduce rise time. Its gate bias is set ~1 VTH above the lower supply rail, enabling robust translation across 1.8 V/2.5 V/3.3 V/5.0 V nodes.
It operates with no direction-control pin: data flow A↔B is determined dynamically by voltage differentials and edge detection. The device includes internal 10 kΩ pull-ups on both A and B ports, supports IOFF during partial power-down, and disables outputs when either VCC(A) or VCC(B) is at GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 50 Mbps push-pull - enables high-speed I²C Fast-mode Plus and UART communication without timing bottlenecks. |
| VCC(A) range | 1.65 V to 3.6 V - compatible with 1.8 V and 3.3 V logic domains as low-voltage side. |
| VCC(B) range | 2.3 V to 5.5 V - supports 2.5 V, 3.3 V, and 5.0 V domains as high-voltage side. |
| Operating temperature | −40 °C to +125 °C - qualified for automotive under-hood and industrial control applications. |
| ESD rating (B port) | HBM Class 3B > 8000 V - ensures robustness against system-level electrostatic discharge in end equipment. |
| IOFF leakage | ±1 µA max at 0 V supplies - prevents damaging backflow current during partial power-down sequences. |
| Propagation delay (B→A) | Max 7.3 ns at −40 °C to +125 °C, VCC(A)=1.8 V, VCC(B)=5.0 V - guarantees tight timing margins in real-time interfaces. |
Pinout & Package
NTS0101GW125 uses the SC-88 (SOT363) plastic surface-mounted package: 6-lead, 2.1 mm × 1.25 mm × 0.95 mm body, gull-wing leads, pin 1 indicator in lower-left corner below marking code "s1".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Low-side supply rail | Reference for A port and OE input; 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 (low-voltage side) | Open-drain port referenced to VCC(A); includes internal 10 kΩ pull-up to VCC(A). |
| B | Bidirectional I/O (high-voltage side) | Open-drain port referenced to VCC(B); includes internal 10 kΩ pull-up to VCC(B). |
| OE | Output enable (active HIGH) | Controls high-impedance state of both A and B ports; referenced to VCC(A); requires pull-down for safe power-up. |
| VCC(B) | High-side supply rail | Reference for B port; sets VOH and VOL thresholds; enables translation up to 5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal-data flow A↔B is determined dynamically by edge detection and voltage differential. |
| Edge-rate acceleration | One-shot circuit reduces tTLH/tTHL by bypassing internal pull-ups for ~50 ns, achieving sub-10 ns transitions even with heavy capacitive loads. |
| IOFF partial power-down | Disables outputs and limits leakage to ±1 µA when either VCC(A) or VCC(B) is at 0 V-prevents backfeed in hot-swap or multi-rail systems. |
| Integrated pull-up resistors | 10 kΩ internal pull-ups on both A and B ports eliminate need for external resistors in standard I²C/SMBus configurations. |
| Wide voltage compatibility | Translates between any combination of 1.8 V, 2.5 V, 3.3 V, and 5.0 V domains without external components or configuration. |

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 |
|---|---|---|---|
| TXS0101DRYR | Single-bit, auto-direction, open-drain; VCCA = 1.2 V–3.6 V, VCCB = 1.65 V–5.5 V; 10 Mbps max; SOT-5X3 package. | Lower speed and narrower VCCA range; lacks IOFF and higher ESD rating (HBM 4 kV). | Choose for cost-sensitive, lower-speed designs where 10 Mbps suffices and IOFF is not required. |
| PCA9306DCUR | 2-bit, dual-supply, open-drain; VREF1 = 1.2 V–3.6 V, VREF2 = 1.65 V–5.5 V; no OE pin; 2 Mbps max; VSSOP8 package. | No output enable, lower speed, no IOFF, smaller ESD rating (HBM 2 kV), fixed 2-channel configuration. | Choose only for space-constrained 2-channel I²C translation where OE control and high-speed operation are unnecessary. |
Compared with TXS0101DRYR and PCA9306DCUR, the NTS0101GW125 delivers superior performance in high-reliability applications: its 50 Mbps rate supports Fast-mode Plus I²C, ±8 kV HBM on B port exceeds industry ESD requirements, and IOFF ensures safe partial power-down-making it optimal for automotive, industrial, and server-grade designs.

FAQ
What is the maximum data rate supported by the NTS0101GW125?
The NTS0101GW125 supports a maximum push-pull data rate of 50 Mbps, verified across its full operating temperature range (−40 °C to +125 °C) and supply voltage combinations. This enables compatibility with I²C Fast-mode Plus (1 MHz), high-speed UART, and other time-critical bidirectional protocols without signal degradation or timing violations.
Does the NTS0101GW125 require external pull-up resistors for I²C operation?
No, the NTS0101GW125 includes internal 10 kΩ pull-up resistors on both the A and B ports-referenced to VCC(A) and VCC(B), respectively-making external pull-ups unnecessary for standard I²C/SMBus implementations. If faster rise times are needed, external resistors may be added in parallel to reduce effective pull-up resistance.
How does the IOFF feature protect the NTS0101GW125 during partial power-down?
The IOFF circuitry in the NTS0101GW125 automatically disables all outputs and limits leakage current to ±1 µA when either VCC(A) or VCC(B) drops to 0 V. This prevents damaging backflow current through the device during hot-swap events, multi-rail sequencing, or fault conditions-ensuring system-level safety without external supervision.
Can the NTS0101GW125 translate between 1.8 V and 5.0 V logic levels?
Yes, the NTS0101GW125 is explicitly rated for bidirectional translation between 1.8 V (within VCC(A) = 1.65 V–3.6 V) and 5.0 V (within VCC(B) = 2.3 V–5.5 V). Its architecture accommodates this combination with guaranteed timing, voltage thresholds, and ESD robustness-no configuration or external components are required.
What is the recommended power-up sequence for the NTS0101GW125?
No strict power-up sequence is required for the NTS0101GW125: either VCC(A) or VCC(B) may be ramped first without risk of damage. However, OE must be held LOW (e.g., via pull-down resistor) during power-up to ensure outputs remain in high-impedance state until both supplies stabilize and the device is ready for operation.
