Product details
Overview
NTS0102DP-Q100H from NXP Semiconductors is a 2-bit automotive-grade 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 at up to 50 Mbit/s, features IOFF partial power-down protection, and operates across –40 °C to +125 °C.
For engineers reviewing the NTS0102DP-Q100H datasheet, NTS0102DP-Q100H pinout, NTS0102DP-Q100H application, or NTS0102DP-Q100H equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, dual-rail voltage flexibility, auto-direction capability without external control, and integrated 10 kΩ pull-up resistors on both ports.
Technical Context
The NTS0102DP-Q100H implements a switch-type architecture using pass-gate NMOS transistors and edge-rate acceleration one-shot circuits to enable fast, direction-agnostic translation. Its gate bias is set ~1 VTH above the lower supply rail, allowing reliable LOW-to-HIGH transitions without external direction control.
It incorporates IOFF circuitry that disables outputs and blocks backflow current when either VCC(A) or VCC(B) is powered down. Internal 10 kΩ pull-ups on all A/B port pins are disabled when OE is LOW, and the device tolerates input voltages up to 5.5 V regardless of supply state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - enables interface with 1.8 V/2.5 V/3.3 V logic domains |
| VCC(B) Range | 2.3 V to 5.5 V - supports 2.5 V/3.3 V/5.0 V systems including legacy automotive microcontrollers |
| Max Data Rate | 50 Mbit/s - sufficient for high-speed I²C Fast Mode Plus (1 Mbit/s) and UART burst transfers |
| IOFF Leakage | < ±1 μA at 25 °C - prevents damaging back-current during partial power-down in mixed-voltage ECUs |
| ESD Rating (B port) | > 8000 V HBM - meets stringent automotive board-level ESD immunity requirements |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood and powertrain control module environments |
| Propagation Delay (A→B) | ≤ 7.3 ns @ –40 °C to +125 °C - ensures timing compliance in real-time sensor bus applications |
Pinout & Package
TSSOP8 package (SOT505-2), 3 mm body width, 0.65 mm pitch, 8-lead plastic thin shrink small outline package with exposed pad option (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | Data I/O (B-side) | Referenced to VCC(B); open-drain output with internal 10 kΩ pull-up to VCC(B) |
| B1 | Data I/O (B-side) | Referenced to VCC(B); identical electrical behavior to B2 |
| GND | Ground reference | Common 0 V return for both supply domains and signal integrity reference plane |
| VCC(B) | High-side supply | Power rail for B-port logic and pull-ups; must be ≥ VCC(A) during operation |
| VCC(A) | Low-side supply | Power rail for A-port logic and pull-ups; sets gate bias for pass transistor |
| OE | Output enable (active HIGH) | Referenced to VCC(A); drives all ports into high-Z when LOW; requires pull-down for safe power-up |
| A2 | Data I/O (A-side) | Referenced to VCC(A); open-drain output with internal 10 kΩ pull-up to VCC(A) |
| A1 | Data I/O (A-side) | Referenced to VCC(A); identical electrical behavior to A2 |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| NTS0102TL-Q100H | XSON8 package (3 × 2 × 0.5 mm) with non-connected center thermal pad; same electrical specs and pinout mapping | Better thermal performance in space-constrained modules; requires evaluation if GD-package PCB has traces under center area | Select for new designs requiring smaller footprint and improved thermal dissipation; not drop-in for GD layouts with center-area routing |
| PCA9306DCURQ1 | TI automotive 2-bit translator; push-pull outputs only; no internal pull-ups; 1.2 V–3.6 V / 1.65 V–5.5 V rails | Lacks auto-direction sensing - requires external direction control; higher drive strength but no open-drain compatibility with I²C | Choose when push-pull signaling dominates and direction control is available; avoid for native I²C/SMBus where open-drain is mandatory |
Compared with NTS0102TL-Q100H, the NTS0102DP-Q100H offers proven TSSOP8 manufacturability and mechanical robustness for reflow and vibration-prone automotive assemblies; versus PCA9306DCURQ1, it delivers native I²C support via open-drain I/O and auto-direction - eliminating GPIO overhead and reducing firmware complexity.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0102DP-Q100H?
The NTS0102DP-Q100H requires VCC(A) ≤ VCC(B) during normal operation. While VCC(A) may exceed VCC(B) during power-up without damage, sustained operation with VCC(A) > VCC(B) violates the device's architectural constraint and risks incorrect pass-gate biasing, leading to degraded VOL, increased propagation delay, or failure to translate rising edges. The recommended margin is VCC(B) ≥ VCC(A) + 0.2 V.
Does the NTS0102DP-Q100H support true bidirectional communication on both A1/A2 and B1/B2 simultaneously?
Yes, the NTS0102DP-Q100H supports simultaneous bidirectional operation across both channels. Each I/O pair (A1↔B1 and A2↔B2) operates independently with auto-direction sensing - meaning data can flow A→B on one channel while B→A flows on the other, provided OE is HIGH and voltage constraints are met. This enables concurrent I²C read/write and status reporting in sensor hub topologies.
How does the internal 10 kΩ pull-up resistor on the B port behave when VCC(B) is unpowered?
When VCC(B) = 0 V, the internal 10 kΩ pull-up on the B port is effectively disconnected due to the IOFF circuitry. The B1/B2 pins enter high-impedance mode with leakage < ±12 μA (per Table 9), preventing back-current into the unpowered domain. This behavior is explicitly validated in the datasheet's power-down leakage specifications and is critical for fault-tolerant automotive domain isolation.
Can the NTS0102DP-Q100H be used with push-pull drivers, or is it limited to open-drain applications?
The NTS0102DP-Q100H is optimized for open-drain interfaces like I²C and SMBus, but it can interface with push-pull drivers when configured per the datasheet's "push-pull driving" conditions (Δt/ΔV ≤ 10 ns/V). However, push-pull use requires careful attention to timing margins and capacitive loading - the NTB0102-Q100 is explicitly recommended by NXP for dedicated push-pull applications due to its enhanced drive strength and slew control.
What is the significance of the "auto direction sensing" feature in the NTS0102DP-Q100H, and how does it differ from manual direction control?
The auto direction sensing in the NTS0102DP-Q100H eliminates the need for an external direction-control signal or GPIO by detecting voltage transitions on either side and dynamically enabling the appropriate pass path. Unlike manual schemes requiring precise timing coordination and additional MCU resources, this feature enables plug-and-play interoperability between heterogeneous voltage domains - reducing firmware overhead and PCB routing complexity in automotive sensor networks.
