Product details
Overview
NVT2002GF,115 from NXP Semiconductors is a 2-bit bidirectional voltage level translator IC for open-drain and push-pull applications, supporting VREF(A) from 1.0 V to 3.6 V and VREF(B) from 1.8 V to 5.5 V, with ≤1.5 ns max propagation delay, 3.5 Ω typical ON-state resistance, and 5 V-tolerant I/Os - deployed in I²C bus interfacing between 1.8 V processors and 3.3 V peripherals.
For engineers reviewing the NVT2002GF,115 datasheet, NVT2002GF,115 pinout, NVT2002GF,115 application, or NVT2002GF,115 equivalent, key selection criteria include enable-controlled high-impedance isolation, flow-through pinout for PCB routing, ESD robustness (4 kV HBM), and compatibility with mixed-voltage I/O domains requiring no direction pin.
Technical Context
The NVT2002GF,115 implements a passive MOSFET-based clamping architecture with symmetrical bidirectional conduction paths per channel, eliminating need for direction control logic. Its EN input is referenced to VREF(B), requiring VREF(B) ≥ VREF(A) + 1 V for reliable operation.
Each channel operates as a low-RON switch: when either An or Bn is LOW, the internal clamp turns ON, establishing a <3.5 Ω path; when both sides are HIGH, pull-up resistors on each side define respective logic-high levels - enabling seamless translation across 1.0 V–5.5 V domain pairs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VREF(A) Range | 1.0 V to 3.6 V - sets low-voltage I/O domain; must be ≥1 V lower than VREF(B) for stable clamping |
| VREF(B) Range | 1.8 V to 5.5 V - defines high-voltage domain and supplies EN logic threshold |
| Max Propagation Delay | ≤1.5 ns - enables >33 MHz operation in 50 pF open-drain systems with 197 Ω pull-up |
| RON (Typ) | 3.5 Ω - minimizes signal distortion and voltage drop under 15 mA pass current |
| I/O Voltage Tolerance | 5 V tolerant - allows direct connection to 3.3 V/5 V buses without external protection |
| ESD Rating | 4 kV HBM (JESD22-A114), 1000 V CDM (JESD22-C101) - protects downstream 1.0–1.8 V logic |
| Operating Temp | −40 °C to +105 °C - qualified for automotive and industrial ambient environments |
Pinout & Package
XSON8U package: plastic extremely thin small outline, no leads, 8 terminals, 3 mm × 2 mm × 0.5 mm body (SOT996-2).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common 0 V return for both voltage domains; required for internal clamp biasing |
| VREFA | Low-side supply reference | Bias source for A-side clamps; sets maximum An output voltage |
| A1, A2 | Low-voltage I/O ports | Bidirectional data lines tied to VREFA domain; require external pull-up if open-drain |
| VREFB | High-side supply reference | Bias source for B-side clamps and EN input; defines Bn logic-high level |
| B1, B2 | High-voltage I/O ports | Bidirectional data lines tied to VREFB domain; require external pull-up if open-drain |
| EN | Enable control input | Active-HIGH switch control referenced to VREFB; must be pulled HIGH via resistor to VREFB for translation |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Enables true bidirectional data flow on shared I²C/SMBus lines without control overhead or timing constraints |
| Flow-through pinout | Minimizes PCB trace crossovers and reduces layout complexity in dense routing environments |
| Lock-up free operation | Guarantees stable state transitions without metastability or latch-up during voltage domain crossings |
| High-impedance isolation (EN = LOW) | Disconnects A/B ports completely - critical for power sequencing and hot-swap I/O isolation |
| Symmetrical fabrication | Ensures matched propagation delay and voltage thresholds across all channels, unlike discrete FET solutions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCA9306DCUR | Requires external VREF1/VREF2 decoupling; higher typical RON (6.5 Ω); no EN pin - always active | Lacks enable control; unsuitable for power-gated or hot-swap scenarios requiring dynamic isolation | Select PCA9306DCUR only when continuous translation is acceptable and board space permits larger TSSOP package |
| NVT2002TLH | Same functional spec; HXSON8 package with thermal pad (SOT1052-2); center pad not electrically connected | Improved thermal performance; compatible with existing NVT2002GD/NVT2002GF PCB footprints if no trace under center area | Prefer NVT2002TLH for new designs needing enhanced thermal dissipation or long-term supply continuity |
Compared with PCA9306DCUR, NVT2002GF,115 adds enable-controlled isolation and lower RON; versus NVT2002TLH, it uses the XSON8U package without thermal pad - making it suitable for space-constrained layouts where thermal load is moderate.

FAQ
What voltage domains does the NVT2002GF,115 support?
The NVT2002GF,115 supports bidirectional translation between VREF(A) = 1.0 V to 3.6 V and VREF(B) = 1.8 V to 5.5 V, with VREF(B) required to be at least 1 V higher than VREF(A) for reliable clamping. Valid combinations include 1.8 V ↔ 3.3 V, 1.2 V ↔ 5.0 V, and 2.5 V ↔ 5.0 V. The NVT2002GF,115 does not support reverse-domain translation (e.g., 3.3 V → 1.8 V only) - its architecture enables true bidirectional operation within these ranges.
Does the NVT2002GF,115 require external pull-up resistors?
Yes, the NVT2002GF,115 requires external pull-up resistors on both A-side and B-side I/O lines for open-drain operation - typically 1.1 kΩ to 10 kΩ depending on bus capacitance and drive strength. Pull-ups are mandatory on B-side for proper HIGH-level establishment; A-side pull-ups may be omitted if the low-voltage driver is push-pull. The NVT2002GF,115 itself contains no internal pull-ups and relies entirely on external components for logic-high biasing.
How is the EN pin used in the NVT2002GF,115?
The EN pin on the NVT2002GF,115 is an active-HIGH enable input referenced to VREF(B). When EN is HIGH (≥VREF(B) − 0.6 V), the translator switches are ON and bidirectional conduction occurs. When EN is LOW, all An and Bn pins enter high-impedance state. To ensure safe power-up behavior, EN must be held LOW until both VREF(A) and VREF(B) are stable - typically achieved with a pull-down resistor to GND and RC filtering.
Can the NVT2002GF,115 be used with push-pull drivers?
Yes, the NVT2002GF,115 supports push-pull drivers on either side, but requires careful design to avoid bus contention: if both An and Bn drivers are push-pull, data must be unidirectional or one side must be 3-stateable with external direction control. The NVT2002GF,115 itself does not resolve contention - it faithfully passes asserted states. For fully bidirectional push-pull use, pairing with tri-state-capable peripherals or using open-drain mode is recommended.
What is the thermal and package compatibility of NVT2002GF,115?
The NVT2002GF,115 uses the XSON8U package (SOT996-2): 3 mm × 2 mm × 0.5 mm, no leads, 8-terminal UTLP footprint. It shares pinout compatibility with NVT2002GD but differs from NVT2002TLH (HXSON8), which adds a non-connected thermal pad. The NVT2002GF,115 operates from −40 °C to +105 °C and dissipates <120 mW at full load - sufficient for standard PCB copper pours without forced airflow.
