Product details
Overview
NTS0102TL-Q100H from NXP Semiconductors is a 2-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in XSON8 package, supporting 1.65–3.6 V on side A and 2.3–5.5 V on side B, with open-drain I/O, IOFF partial power-down, and 50 Mbit/s data rate - used for I²C/SMBus interface between mixed-voltage subsystems in automotive body control modules.
For engineers reviewing the NTS0102TL-Q100H datasheet, NTS0102TL-Q100H pinout, NTS0102TL-Q100H application, or NTS0102TL-Q100H equivalent, key selection considerations include its auto-direction sensing architecture, guaranteed operation from –40 °C to +125 °C, IOFF-enabled safe power sequencing, and compatibility with 1.8 V/3.3 V/5.0 V node translation without external direction control.
Technical Context
The NTS0102TL-Q100H implements a switch-type voltage translator using pass-gate NMOS (T3) biased at ~VCC(LV) + Vth, enabling bidirectional level shifting without direction pins. Its internal one-shot edge accelerator activates on input transitions crossing VCCI/2, reducing tTLH by driving PMOS transistors (T1/T2) to bypass 10 kΩ pull-ups during rising edges.
Each port integrates 10 kΩ internal pull-up resistors (A to VCC(A), B to VCC(B)), disabled when OE = LOW. The device enforces VCC(A) ≤ VCC(B) during active operation but tolerates any power-up sequence, and enters full high-impedance state if either supply drops to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range A | 1.65 V to 3.6 V - supports 1.8 V and 3.3 V logic domains as low-side interface |
| Supply range B | 2.3 V to 5.5 V - enables direct connection to 2.5 V, 3.3 V, or 5.0 V buses |
| Data rate | 50 Mbit/s - sufficient for fast-mode-plus I²C (1 Mbps) and UART up to 25 Mbps |
| IOFF leakage | <±12 μA at –40 °C to +125 °C - prevents backflow current during partial power-down |
| Operating temp | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for under-hood automotive use |
| ESD rating B | >8 kV HBM (JESD22-A114E Class 3B) - robust against handling and system-level ESD events |
| Propagation delay | ≤7.3 ns (A→B, VCC(A)=1.8 V, VCC(B)=5.0 V, –40 °C to +125 °C) - ensures timing compliance in high-speed interconnects |
Pinout & Package
NTS0102TL-Q100H uses SOT1052-2: XSON8 package (3 mm × 2 mm × 0.5 mm, no leads, 8 terminals), with exposed center pad electrically isolated from die - compatible with GD-package PCB layouts where no trace exists beneath the pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 (B2, B1) | B-side bidirectional I/O | Referenced to VCC(B); open-drain capable; accepts up to 5.5 V inputs |
| 2 | GND | Common reference for both supplies; required for IOFF and ESD path |
| 3 | VCC(A) | Low-voltage supply input (1.65–3.6 V); powers A-side logic and internal bias |
| 4, 5 (A2, A1) | A-side bidirectional I/O | Referenced to VCC(A); includes 10 kΩ internal pull-up to VCC(A) |
| 6 | OE | Active-HIGH output enable (VCC(A)-referenced); forces all I/O into high-Z when LOW |
| 7 | VCC(B) | High-voltage supply input (2.3–5.5 V); powers B-side logic and pull-ups |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals or GPIOs, reducing MCU pin count and firmware complexity in bidirectional protocols like I²C |
| IOFF partial power-down | Disables outputs and blocks damaging back-current when either VCC(A) or VCC(B) is unpowered - critical for hot-swap and domain-isolation systems |
| Integrated 10 kΩ pull-ups | Reduces external component count on both sides; pull-ups are automatically disabled when OE = LOW to prevent contention during shutdown |
| One-shot edge acceleration | Improves rising-edge speed (tTLH) by temporarily lowering output impedance to ~50–70 Ω, enabling reliable 50 Mbit/s operation without external drivers |
| Wide VCC(A)/VCC(B) ratio support | Supports translation between 1.8 V ↔ 5.0 V (2.78× ratio) while maintaining VOL ≤ 0.4 V and VOH ≥ 0.67×VCCO across temperature |

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 |
|---|---|---|---|
| NTS0102GD-Q100 | No center pad; identical pinout, electrical specs, and thermal profile except for mechanical pad presence | Same automotive qualification; GD lacks exposed center pad - lower thermal resistance not required in low-power I²C apps | Select GD for cost-sensitive, non-thermally constrained designs; TL preferred when mechanical stability or marginally improved thermal performance is needed |
| PCA9306DCURQ1 | Requires external direction control (DIR pin); no IOFF; max 3.6 V on both sides; 1.2–3.6 V supply range | Not rated for 5.0 V B-side operation; unsuitable for 1.8 V ↔ 5.0 V translation or automotive hot-swap scenarios | Choose PCA9306DCURQ1 only for simpler 1.8 V ↔ 3.3 V I²C links where direction is statically known and partial power-down is unnecessary |
Compared with NTS0102GD-Q100, the NTS0102TL-Q100H offers identical functionality with enhanced mechanical mounting via its isolated center pad, while PCA9306DCURQ1 lacks auto-direction sensing and 5.0 V support - making NTS0102TL-Q100H the sole option for robust, high-ratio, automotive-grade bidirectional translation without direction pins.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0102TL-Q100H?
The NTS0102TL-Q100H requires VCC(A) ≤ VCC(B) during active operation, with VCC(A) ranging from 1.65 V to 3.6 V and VCC(B) from 2.3 V to 5.5 V. This permits up to a 3.85 V differential (e.g., VCC(A) = 1.65 V, VCC(B) = 5.5 V), confirmed in Table 9 and Section 9 of the datasheet. Exceeding VCC(A) > VCC(B) risks latch-up or undefined behavior.
Does the NTS0102TL-Q100H support true push-pull driving on both ports, or is it limited to open-drain configurations?
The NTS0102TL-Q100H supports both open-drain and push-pull drivers on either port, as stated in Section 13.3 and Table 4. However, its architecture is optimized for open-drain use (e.g., I²C), and push-pull operation requires careful timing to avoid contention - the one-shot accelerator is designed for rising edges typical of pull-up-based buses, not active-high push-pull sources.
How does the IOFF circuitry in the NTS0102TL-Q100H protect the system during partial power-down?
The IOFF circuitry in the NTS0102TL-Q100H disables all outputs and blocks current flow between A and B ports when either VCC(A) or VCC(B) drops to GND, limiting leakage to ±12 μA (Table 9). This prevents damaging back-current through powered subsystems - a critical feature for automotive domain isolation and hot-plug interfaces where supplies may be sequenced independently.
Can the internal 10 kΩ pull-up resistors on the NTS0102TL-Q100H be disabled independently of the OE pin?
No - the internal 10 kΩ pull-up resistors on both A and B ports are automatically disabled only when OE is driven LOW, as specified in Section 13.7. There is no separate control signal or register setting to disable them individually or conditionally; they remain active whenever OE = HIGH and their respective supply is present.
Is the center pad on the NTS0102TL-Q100H's XSON8 package electrically connected to the silicon die?
No - the center pad on the NTS0102TL-Q100H (SOT1052-2 package) is not electrically connected to the silicon die, as explicitly stated in the Discontinuation Notice and Section 13.8. It is mechanically bonded but isolated; therefore, it may be left floating, connected to GND for thermal relief, or omitted from the PCB layout without affecting electrical performance of the NTS0102TL-Q100H.
