Product details
Overview
NTS0102DP,125 from NXP Semiconductors is a 2-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 supports I²C/SMBus interfaces, features IOFF partial power-down protection, and operates across –40 °C to +125 °C.
For engineers reviewing the NTS0102DP,125 datasheet, NTS0102DP,125 pinout, NTS0102DP,125 application, or NTS0102DP,125 equivalent, key selection criteria include voltage translation range, auto-direction capability, open-drain compatibility with I²C buses, IOFF-enabled power-down safety, and TSSOP8 package suitability for space-constrained industrial control and sensor interface designs.
Technical Context
The NTS0102DP,125 implements a switch-type architecture using pass-gate transistors and output edge-rate accelerators to enable direction-agnostic voltage translation without external control signals. Its gate bias circuit sets the pass transistor threshold ~1 VTH above the lower supply rail.
Each channel integrates internal 10 kΩ pull-up resistors referenced to its respective supply (VCC(A) for A1/A2, VCC(B) for B1/B2), and the OE input-active HIGH and referenced to VCC(A)-controls high-impedance disable of all I/Os with ≤25 ns enable/disable timing under no-load conditions.
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 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 connection to 3.3 V or 5.0 V peripherals, including legacy microcontrollers and sensors. |
| Max Data Rate | 50 Mbit/s (push-pull): Sustains high-speed bidirectional communication in fast GPIO or UART applications with minimal propagation delay. |
| IOFF Leakage | <±1 μA at 25 °C: Prevents damaging backflow current during partial power-down when either supply is inactive. |
| Operating Temp | –40 °C to +125 °C: Qualified for automotive under-hood, industrial motor drives, and harsh-environment embedded systems. |
| ESD Rating (B port) | HBM Class 3B > 8000 V: Provides robust protection against handling and system-level ESD events on higher-voltage I/O lines. |
| Propagation Delay | A↔B: 2.5–7.3 ns (typ./max, depending on VCC pair): Ensures deterministic timing in real-time I²C arbitration and clock stretching. |
Pinout & Package
TSSOP8 package (SOT505-2), 3 mm body width, 0.65 mm pitch, lead length 0.5 mm - suitable for automated assembly and thermal management in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 (B2, B1) | Data I/O (VCC(B)-referenced) | Bidirectional open-drain pins tied to VCC(B); support 5.5 V-tolerant inputs and drive loads referenced to VCC(B). |
| 2 (GND) | Ground reference | Common return path for both supply domains; required for stable IOFF operation and ESD current discharge. |
| 3 (VCC(A)) | Low-voltage supply | Powers A-side logic and OE input; must be ≤ VCC(B) during steady-state operation per design constraint. |
| 4, 5 (A2, A1) | Data I/O (VCC(A)-referenced) | Bidirectional open-drain pins tied to VCC(A); include internal 10 kΩ pull-ups to VCC(A). |
| 6 (OE) | Output enable (active HIGH) | When LOW, forces all I/Os into high-impedance state; referenced to VCC(A); requires pull-down during power-up for fail-safe disable. |
| 7 (VCC(B)) | High-voltage supply | Powers B-side logic and I/O drivers; enables translation up to 5.5 V while tolerating 6.5 V absolute max. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals in bidirectional buses like I²C, reducing PCB routing and firmware overhead. |
| Integrated 10 kΩ pull-ups | Reduces external component count on both A and B sides-each I/O has dedicated pull-up referenced to its local supply rail. |
| IOFF partial power-down | Disables outputs and limits leakage to <±1 μA when either VCC(A) or VCC(B) is at GND, preventing back-current damage in mixed-power systems. |
| 5.5 V-tolerant A-port inputs | Allows safe connection of 5 V signals to A-side pins even when VCC(A) = 1.8 V, simplifying mixed-voltage debug interfaces and level-shifter staging. |
| Open-drain compatible | Supports standard I²C bus topology with external pull-ups; internal architecture avoids contention during bidirectional transitions. |

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 |
|---|---|---|---|
| NTS0102GT,115 | XSON8 (1 × 1.95 × 0.5 mm) package vs TSSOP8; same electrical specs and temperature range (–40 °C to +125 °C). | Preferred for ultra-compact PCBs where footprint and thermal mass are constrained; lacks exposed leads for visual inspection and rework. | Select NTS0102GT,115 when board space is critical and automated optical inspection is available; verify solder paste volume for XSON8 reflow profile. |
| TXS0102DCUR | Texas Instruments part; 2-bit, auto-direction, open-drain, but rated only to +85 °C and lacks IOFF circuitry (no partial power-down). | Suitable for commercial-grade consumer electronics; not qualified for automotive or extended-temperature industrial use. | Choose TXS0102DCUR only for cost-sensitive, non-automotive applications where ambient temperature stays below 85 °C and full power-down sequencing is guaranteed. |
Compared with NTS0102GT,115, the NTS0102DP,125 offers easier manual rework and thermal monitoring via visible leads; compared with TXS0102DCUR, it delivers critical IOFF protection and extended temperature operation essential for industrial reliability.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0102DP,125?
The NTS0102DP,125 requires VCC(A) ≤ VCC(B) during steady-state operation, but permits VCC(A) ≥ VCC(B) during power-up without damage. The absolute maximum ratings allow VCC(A) up to +6.5 V and VCC(B) up to +6.5 V independently, though functional translation is only guaranteed within the recommended ranges: VCC(A) = 1.65 V–3.6 V and VCC(B) = 2.3 V–5.5 V. Exceeding these ranges may impair auto-direction sensing or increase leakage.
Does the NTS0102DP,125 support push-pull drivers on both A and B ports, or is it limited to open-drain configurations?
The NTS0102DP,125 supports both open-drain and push-pull drivers on A and B ports, but its architecture is optimized for open-drain use cases like I²C. When used with push-pull drivers, the device functions correctly, though NXP recommends the NTB0102 for dedicated push-pull applications due to its enhanced drive strength and timing characteristics. The NTS0102DP,125's 50 Mbit/s rating applies to push-pull operation.
How does the IOFF circuitry in the NTS0102DP,125 protect the system during partial power-down?
The IOFF circuitry in the NTS0102DP,125 disables all I/Os and limits leakage current to <±1 μA when either VCC(A) or VCC(B) drops to GND, preventing damaging backflow current through the transceiver. This ensures safe operation in systems where one voltage domain powers down independently-such as during FPGA reconfiguration or modular subsystem shutdown-without requiring external isolation switches or diodes.
Can the internal 10 kΩ pull-up resistors on the NTS0102DP,125 be disabled or overridden?
The internal 10 kΩ pull-up resistors on the NTS0102DP,125 (to VCC(A) on A1/A2, to VCC(B) on B1/B2) are always active when the device is powered and OE is HIGH. They are automatically disabled when OE is driven LOW, placing all I/Os in high-impedance state. To override the value, add an external pull-up resistor in parallel; however, this lowers the effective resistance and increases VOL, requiring verification against sink-current requirements of the driven device.
Is the NTS0102DP,125 pin-compatible with other variants in the NTS0102 family, such as NTS0102GT or NTS0102TL?
No-the NTS0102DP,125 uses the TSSOP8 (SOT505-2) package with a specific 8-pin linear pinout, while NTS0102GT and NTS0102TL use XSON8 packages with different pin mappings and land patterns. Although electrically identical, they are not mechanically interchangeable. PCB layout must match the exact package variant; migration requires redesign of footprint and solder mask, not just component substitution.
