Product details
Overview
NVT2002DP,118 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 operation across −40 °C to +105 °C - used in I²C bus interfacing between 1.8 V processors and 3.3 V peripherals.
For engineers reviewing the NVT2002DP,118 datasheet, NVT2002DP,118 pinout, NVT2002DP,118 application, or NVT2002DP,118 equivalent, key selection criteria include enable-controlled high-impedance isolation, flow-through TSSOP8 pinout, 5 V-tolerant I/Os, ESD robustness (4 kV HBM), and compatibility with mixed-voltage SoC-to-peripheral interconnects requiring no direction pin.
Technical Context
The NVT2002DP,118 implements a passive clamping architecture using integrated MOSFET switches per channel, enabling true bidirectional translation without direction control logic. Its EN input is referenced to VREF(B), requiring VREF(B) ≥ VREF(A) + 1 V for reliable operation.
Each channel features matched Ron (≤5 Ω typ) and low off-state capacitance (4–6 pF), ensuring minimal skew and signal distortion across A1/B1 and A2/B2 pairs. The device operates in two states: enabled (low-impedance An↔Bn connection) and disabled (high-Z isolation), with EN pull-up to VREF(B) via 200 kΩ resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VREF(A) Range | 1.0 V to 3.6 V - sets low-voltage domain reference for A-side I/O clamping and voltage limiting |
| VREF(B) Range | 1.8 V to 5.5 V - supplies high-voltage domain reference and powers EN input circuitry |
| Max Propagation Delay | ≤1.5 ns - enables reliable operation up to ~33 MHz in 50 pF open-drain systems with 197 Ω pull-up |
| ON-State Resistance | 3.5 Ω typ - minimizes voltage drop and signal attenuation during active translation |
| ESD Protection | 4 kV HBM, 1000 V CDM - protects downstream 1.0–1.8 V logic from system-level transients |
| Operating Temp | −40 °C to +105 °C - qualified for automotive under-hood and industrial control environments |
| I/O Voltage Tolerance | 5 V tolerant - allows direct connection to 3.3 V/5 V buses without external protection |

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 | 2-bit translator with auto-direction sensing; 1.2 V to 3.6 V / 1.8 V to 5.5 V range; 1.5 ns tPD; 5 V-tolerant; same TSSOP8 package | Requires external 100 nF VREF decoupling; slightly higher Ron (5 Ω typ); lacks EN pin - always enabled | Select PCA9306DCUR when enable control is unnecessary and board space permits identical footprint. |
| NVT2002TLH | Same functional spec; HXSON8 package (3 × 2 × 0.5 mm) with thermal pad; pin-compatible but center pad not electrically connected | Smaller footprint and improved thermal performance; requires evaluation of PCB trace placement under center pad if replacing NVT2002DP,118 | Select NVT2002TLH for space-constrained designs where thermal management is critical and layout supports HXSON8 mounting. |
Compared with PCA9306DCUR, NVT2002DP,118 adds hardware enable control and lower Ron for reduced signal distortion; compared with NVT2002TLH, it offers proven manufacturability in TSSOP8 with no center-pad layout constraints, simplifying first-pass design validation.

FAQ
What voltage ranges does the NVT2002DP,118 support for level translation?
The NVT2002DP,118 supports VREF(A) from 1.0 V to 3.6 V and VREF(B) from 1.8 V to 5.5 V. For reliable operation, VREF(B) must be at least 1 V higher than VREF(A). Valid combinations include 1.8 V ↔ 3.3 V, 1.2 V ↔ 5.0 V, and 2.5 V ↔ 5.0 V. The NVT2002DP,118 does not support reverse translation (e.g., 3.3 V → 1.0 V without external bias).
Does the NVT2002DP,118 require external pull-up resistors?
Yes - external pull-up resistors are required on both A-side and B-side I/O lines for open-drain operation. Typical values range from 750 Ω to 1.82 kΩ depending on drive strength and voltage pair; Table 6 in the NXP datasheet provides minimum recommended values. Pull-ups are not needed for push-pull drivers unless bus contention mitigation is required.
How is the EN pin of the NVT2002DP,118 configured for proper operation?
The EN pin of the NVT2002DP,118 must be referenced to VREF(B) and pulled HIGH via a 200 kΩ resistor to VPU(D) (typically 3.3 V or 5 V). During power-up or power-down, EN must be held LOW to ensure high-impedance isolation. A 0.1 µF capacitor on VREF(B) is recommended to stabilize the enable threshold.
Can the NVT2002DP,118 be used in push-pull applications?
Yes - the NVT2002DP,118 supports both open-drain and push-pull topologies. In push-pull mode, outputs must be 3-stateable or unidirectional to prevent contention; if both sides drive actively, direction control or time-multiplexing is required. The NVT2002DP,118 itself does not provide direction arbitration - it only translates voltage levels bidirectionally when enabled.
What is the maximum operating frequency supported by the NVT2002DP,118?
The NVT2002DP,118 supports up to ~33 MHz in open-drain configurations with 50 pF load and 197 Ω pull-up, based on its ≤1.5 ns propagation delay. Actual maximum frequency depends on system-level factors: total node capacitance, pull-up resistor value, driver strength, and PCB layout. Rise/fall times are dominated by RPU × CL and driver sink capability, not the NVT2002DP,118's internal delay.
