Product details
Overview
NXB0106BQ-Q100 from Nexperia is a 6-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control, operating across VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V. It enables seamless interface between automotive subsystems at mismatched logic voltages (e.g., 1.8 V microcontroller to 3.3 V sensor bus), features IOFF partial power-down protection, and is AEC-Q100 Grade 1 qualified for under-hood applications.
For engineers reviewing the NXB0106BQ-Q100 datasheet, NXB0106BQ-Q100 pinout, NXB0106BQ-Q100 application, or NXB0106BQ-Q100 equivalent, key selection criteria include auto-direction operation without external control, asymmetric supply tolerance, IOFF leakage < ±2 μA during power-down, and DHVQFN16 package compatibility with AOI-enabled solder joint inspection.
Technical Context
The device implements edge-detecting one-shot circuitry on both A and B ports to autonomously determine data flow direction-no external DIR signal required. Each channel uses weak-output drivers (70 Ω typical at 1.2–1.8 V, 40 Ω at 3.3–5.0 V) that are overdrivable by opposing bus drivers, enabling true bidirectional translation on shared lines.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, limiting backflow current to ±2 μA across -40 °C to +125 °C. Input thresholds track respective supply rails (VIH = 0.65×VCCI, VIL = 0.35×VCCI), ensuring robust noise margins across all supported voltage combinations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - supports 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V domains as side-A logic reference |
| VCC(B) Range | 1.65 V to 5.5 V - accommodates 1.8 V/2.5 V/3.3 V/5.0 V interfaces as side-B logic reference |
| Propagation Delay | 0.8–11.9 ns - varies with supply pair and temperature; min 0.8 ns (A→B, VCC(A)=3.3 V, VCC(B)=5.0 V, -40 °C to +125 °C) |
| Data Rate | Up to 110 Mbps - verified at VCC(A)=3.3 V / VCC(B)=5.0 V, -40 °C to +85 °C |
| IOFF Leakage | ±2 μA max - prevents damaging backflow when either supply is powered down |
| ESD Robustness | HBM 15 kV (B port), 2.5 kV (A port); CDM 1.5 kV - exceeds automotive system-level ESD requirements |
| Operating Temp | -40 °C to +125 °C - full functionality across extended automotive ambient range |
Pinout & Package
DHVQFN16 package (SOT763-1), 2.5 × 3.5 × 0.85 mm body, side-wettable flanks for automated optical inspection (AOI) of solder joints. Thermal pad (terminal 1 index area) is electrically isolated; if soldered, must remain floating or connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A6 | Side-A bidirectional I/O | Referenced to VCC(A); accept inputs up to 5.5 V; drive outputs compliant with VCC(A) logic levels |
| B1–B6 | Side-B bidirectional I/O | Referenced to VCC(B); tolerate 0–5.5 V input; output swing defined by VCC(B) |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces all I/Os into high-impedance OFF-state |
| VCC(A) | Side-A supply | Powers A-side logic and I/O circuitry; must be ≤ VCC(B) during active operation |
| VCC(B) | Side-B supply | Powers B-side logic and I/O circuitry; enables translation to higher-voltage domains |
| GND | Ground reference | Common 0 V reference for all signals and supplies; two GND terminals (pins 9 and 16) reduce ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal; internal one-shots detect edge transitions to enable instantaneous bidirectional flow |
| Asymmetric dual-supply operation | Independent VCC(A) and VCC(B) rails allow translation between non-matching voltage domains (e.g., 1.8 V ↔ 5.0 V) without level-shifter ICs or discrete solutions |
| IOFF partial power-down | Prevents destructive back-current when one supply is off; maintains < ±2 μA leakage across full automotive temperature range |
| DHVQFN16 with side-wettable flanks | Enables automated optical inspection (AOI) of solder joints for zero-defect automotive manufacturing compliance |
| AEC-Q100 Grade 1 qualification | Validated for operation from -40 °C to +125 °C ambient; meets stress testing, reliability, and failure rate requirements for automotive safety-critical systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXB0106PW-Q100 | TSSOP16 package (SOT403-1); 4.4 mm body width; no side-wettable flanks | Suitable for manual assembly or wave-soldered automotive modules where AOI is not mandated | Select when board-level AOI is unnecessary and thermal dissipation requirements are lower than DHVQFN16 |
| NXS0106-Q100 | Open-drain architecture; supports I²C, SMBus, 1-Wire; no auto-direction sensing | Required for true open-drain protocols where bus arbitration and pull-up dependency are essential | Choose only for I²C/SMBus applications; not interchangeable due to fundamental driver topology difference |
Compared with NXB0106PW-Q100, the BQ variant offers superior thermal performance and AOI-compatible solder joints for high-reliability SMT lines; versus NXS0106-Q100, it delivers autonomous bidirectional flow but cannot replace open-drain bus protocols requiring wired-AND behavior.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) must never exceed VCC(B) during active operation per datasheet Section 8, though transient overshoot during power-up is tolerated. The absolute maximum ratings allow both supplies up to +6.5 V independently, but functional operation requires VCC(A) ≤ VCC(B) to prevent latch-up and ensure correct auto-direction detection.
Can NXB0106BQ-Q100 translate between 1.2 V and 5.0 V simultaneously?
Yes - VCC(A) can be set to 1.2 V while VCC(B) operates at 5.0 V, enabling direct interface between ultra-low-power 1.2 V logic and legacy 5.0 V peripherals. Input tolerance up to 5.5 V on both sides and rail-referenced thresholds ensure robust operation across this full range.
Does the DHVQFN16 package require special PCB layout considerations?
Yes - the exposed thermal pad (terminal 1 index area) must be either left unsoldered or connected to GND with a thermally isolated copper pour. If soldered, the pad must not be electrically tied to any voltage plane other than GND, and solder stencil aperture should match manufacturer-recommended dimensions to avoid voiding.
How does auto-direction sensing behave during signal transitions?
Internal one-shot circuits detect rising/falling edges on either A or B ports and activate corresponding PMOS/NMOS drivers for <10 ns to accelerate transitions. This allows immediate reversal of data flow without propagation delay penalty - verified by <0.5 ns output skew between channels under identical switching conditions.
