Product details
Overview
NVT2010BS,115 from NXP Semiconductors is a 10-bit bidirectional voltage-level translator 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 HVQFN24 package. It enables seamless I²C, SMBus, and GPIO interfacing between 1.0–3.3 V logic domains and 3.3–5.0 V peripherals without direction control.
For engineers reviewing the NVT2010BS,115 datasheet, NVT2010BS,115 pinout, NVT2010BS,115 application, or NVT2010BS,115 equivalent, key selection criteria include bidirectional operation without direction pin, 5 V-tolerant B-side I/Os, flow-through pinout for PCB routing, EN-controlled high-impedance isolation, and ESD robustness (4 kV HBM / 1000 V CDM).
Technical Context
The NVT2010BS,115 implements a passive MOSFET-based clamping architecture with symmetrical An–Bn channel switches, enabling true bidirectional translation in both open-drain and push-pull configurations. Its EN input is referenced to Vref(B), requiring VI(EN) ≥ Vref(A) + 0.6 V and Vref(B) ≥ Vref(A) + 1 V for reliable operation.
Each of the 10 channels features matched electrical characteristics-≤0.1 ns inter-channel skew in propagation delay and uniform Ron across all pairs-eliminating timing skew issues common in discrete transistor solutions. The device operates over -40 °C to +85 °C and supports transmission speeds <33 MHz under 50 pF load with 197 Ω pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Vref(A) Range | 1.0 V to 3.6 V - sets low-voltage domain reference; must be at least 1 V below Vref(B) for stable clamping |
| Vref(B) Range | 1.8 V to 5.5 V - powers high-voltage side and EN input; determines maximum B-side output voltage |
| Max Propagation Delay | ≤1.5 ns - ensures sub-33 MHz operation with 50 pF load and 197 Ω pull-up in open-drain mode |
| ON-State Resistance | 3.5 Ω typical - minimizes signal distortion and voltage drop across An–Bn path during conduction |
| ESD Protection | 4 kV HBM (JESD22-A114), 1000 V CDM (JESD22-C101) - protects downstream 1.0–1.8 V devices from system-level transients |
| Operating Temperature | -40 °C to +85 °C - qualified for industrial and automotive body electronics environments |
| I/O Voltage Tolerance | 5 V tolerant on B-side pins - allows direct connection to 3.3 V/5 V buses without external protection |
Pinout & Package
HVQFN24 package: plastic thermal enhanced very thin quad flat package, no leads, 24 terminals, body size 4 × 4 × 0.85 mm, exposed thermal pad, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common 0 V return for both A- and B-side circuitry; must be low-inductance connection |
| VREFA | Low-voltage reference supply | Bias source for A-side clamp transistors; sets maximum An output voltage |
| VREFB | High-voltage reference supply | Bias source for B-side clamp transistors and EN input; defines Bn output swing ceiling |
| EN | Enable control input | Active-HIGH enable referenced to VREFB; LOW forces all An/Bn into high-Z state |
| A1–A10 | Low-voltage I/O ports | Connect to 1.0–3.6 V domain; require external pull-up only if used as open-drain outputs |
| B1–B10 | High-voltage I/O ports | Connect to 1.8–5.5 V domain; require external pull-up resistors for open-drain operation |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Enables automatic bidirectional data flow on shared buses like I²C without external control logic |
| Flow-through pinout | Minimizes PCB trace length and crosstalk by aligning A1–A10 and B1–B10 in adjacent rows |
| Lock-up free operation | Guarantees stable DC biasing under mismatched power-up sequences or partial domain failures |
| 5 V-tolerant B-side I/Os | Allows direct interface to legacy 5 V peripherals without level-shifting buffers or series resistors |
| Symmetrical channel matching | Ensures uniform timing and voltage transfer across all 10 channels, critical for parallel bus integrity |
Applications
| I²C Bus Translation | GPIO Domain Bridging |
|---|---|
Use Scenario: Interfacing a 1.8 V microcontroller I²C controller with a 3.3 V sensor or EEPROM on the same bus. IC Role / Device Role / Timing Role: Bidirectional level shifter on SDA/SCL lines, preserving I²C timing requirements and open-drain behavior. Use Value: Eliminates need for dual-supply I²C buffers; maintains full 100 kHz/400 kHz/1 MHz compliance with ≤1.5 ns added delay. | Use Scenario: Connecting 1.2 V FPGA I/O banks to 3.3 V industrial I/O modules (e.g., digital inputs/outputs). IC Role / Device Role / Timing Role: Translates control/status signals across isolated power domains while maintaining push-pull or open-drain drive capability. Use Value: Enables mixed-voltage system design without custom gate arrays; supports up to 10 independent signal paths in one HVQFN24 package. |
| Multi-Voltage SoC Interface | Fail-Safe Power Domain Isolation |
Use Scenario: Level-shifting between CPU core (1.0 V) and chipset I/O (3.3 V or 5 V) in embedded compute platforms. IC Role / Device Role / Timing Role: Provides per-signal voltage translation for address/data/control lines with matched propagation delay. Use Value: Reduces timing skew vs. discrete solutions; supports simultaneous translation of 10-bit parallel interfaces at >20 MHz. | Use Scenario: Isolating communication between two nominally 3.3 V domains where one may collapse to 0 V during brown-out or fault. IC Role / Device Role / Timing Role: Acts as fail-safe barrier that disables translation when either Vref(A) or Vref(B) drops below operational threshold. Use Value: Prevents back-powering or contention during partial power loss; EN automatically deactivates when Vref(B) falls below Vref(A)+0.6 V. |
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 | 8-bit, TSSOP8 package; lower channel count; 1.2 V to 3.3 V / 1.8 V to 5.5 V range; 3.5 ns max tPD | Limited to 8 signals; not suitable for 10-bit parallel interfaces or space-constrained HVQFN layouts | Select PCA9306DCUR only for cost-sensitive 8-signal I²C applications where board area is not constrained. |
| NVT2008BQ,118 | 8-bit variant in DHVQFN20; identical architecture and specs except bit width and package; same 3.5 Ω Ron and 1.5 ns tPD | Requires redesign for 10-signal systems; incompatible pinout and footprint despite functional similarity | Choose NVT2008BQ,118 only when reducing channel count is acceptable and PCB layout allows DHVQFN20 placement. |
Compared with PCA9306DCUR and NVT2008BQ,118, the NVT2010BS,115 delivers 10-channel density in HVQFN24, enabling compact routing for parallel buses and eliminating interposer boards needed for 8-bit alternatives.

FAQ
What is the minimum Vref(B) voltage required for reliable operation of the NVT2010BS,115?
The NVT2010BS,115 requires Vref(B) ≥ Vref(A) + 1 V for optimal clamping performance. For example, with Vref(A) = 1.8 V, Vref(B) must be at least 2.8 V; the datasheet specifies a minimum Vref(B) of 2.1 V under all conditions, but stable operation mandates the 1 V headroom. This ensures proper EN activation and prevents incomplete turn-on of internal pass transistors.
Can the NVT2010BS,115 be used with push-pull drivers on both sides?
Yes, the NVT2010BS,115 supports push-pull drivers on both A and B sides-but only if signals are unidirectional or outputs are 3-stateable with external direction control. Without such control, simultaneous HIGH-to-LOW contention can occur. The NVT2010BS,115 itself does not resolve contention; it faithfully translates voltage levels regardless of driver type.
Does the NVT2010BS,115 require external pull-up resistors on both sides?
External pull-up resistors are mandatory on the B-side (high-voltage domain) for open-drain operation, and recommended on the A-side when driving open-drain loads. Pull-ups are not required for push-pull use, but may improve noise immunity. The NVT2010BS,115 does not integrate pull-ups; resistor values depend on sink current, bus capacitance, and speed-e.g., 1.18 kΩ for 3.3 V B-side with 3 mA drive.
How does the EN pin behave during power-up sequences?
The EN pin of the NVT2010BS,115 is referenced to Vref(B), so it must be held LOW (via pull-down or controlled logic) until Vref(B) is stable and ≥ Vref(A) + 0.6 V. If EN rises before this condition is met, the device may enter an undefined state. A 200 kΩ pull-up to Vref(B) with optional RC filter is recommended to ensure monotonic enable timing.
Is the NVT2010BS,115 compatible with I²C Fast Mode Plus (1 MHz)?
Yes-the NVT2010BS,115 supports I²C Fast Mode Plus up to 1 MHz when used with appropriate pull-up resistors (e.g., ≤1.18 kΩ for 3.3 V B-side) and total bus capacitance ≤400 pF. Its ≤1.5 ns propagation delay and low 3.5 Ω Ron minimize rise/fall time degradation, and its 5 V-tolerant B-side handles standard 3.3 V I²C signaling without additional components.
