Product details
Overview
NXB0108BQ-Q100 from Nexperia is an 8-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in DHVQFN20 package, supporting VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V, with IOFF partial power-down protection and AEC-Q100 Grade 1 qualification for automotive infotainment and ADAS domain controllers.
For engineers reviewing the NXB0108BQ-Q100 datasheet, NXB0108BQ-Q100 pinout, NXB0108BQ-Q100 application, or NXB0108BQ-Q100 equivalent, key selection criteria include asymmetric supply range compatibility, 3-state control via OE referenced to VCC(A), auto-direction sensing without external control logic, and thermal-enhanced DHVQFN package with side-wettable flanks for AOI-capable solder joint inspection.
Technical Context
The device implements edge-triggered one-shot circuitry on both A and B ports to dynamically enable PMOS/NMOS output drivers during signal transitions-accelerating rise/fall times without requiring direction-control pins. Its weak static drive strength (70 Ω typical at 1.2–1.8 V, 40 Ω at 3.3–5.0 V) enables bus contention resolution while maintaining defined output levels in idle states.
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 scale with respective supply rails (VIH = 0.65×VCCI, VIL = 0.35×VCCI), ensuring robust noise margins across mixed-voltage interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side I/Os and OE; must be ≤ VCC(B) during operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/Os; supports translation to 5 V legacy systems |
| Propagation Delay | 0.8–11.9 ns - varies by supply pair and temperature; min 0.8 ns (A→B, 3.3 V/5.0 V, −40 °C to +125 °C) |
| Data Rate | Up to 110 Mbps - achievable at VCC(A)=3.3 V/VCC(B)=5.0 V within −40 °C to +125 °C |
| IOFF Leakage | ±2 μA max - prevents damaging backflow when one supply is powered down |
| ESD Robustness | HBM 15 kV (B port), 2.5 kV (A port); CDM 1.5 kV - meets automotive system-level ESD requirements |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cockpit electronics |
Pinout & Package
DHVQFN20 package (SOT764-1), 2.5 × 4.5 × 0.85 mm body, side-wettable flanks for automated optical inspection of solder joints; thermal pad (GND(1)) is electrically isolated unless explicitly connected to system ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | A-side data I/O | Bidirectional signals referenced to VCC(A); auto-sensed direction; tolerate up to 5.5 V input |
| B1–B8 | B-side data I/O | Bidirectional signals referenced to VCC(B); driven by internal one-shots during transitions |
| OE | Output enable | Active-HIGH control referenced to VCC(A); forces all I/Os into high-impedance state when LOW |
| VCC(A) | A-port supply | Provides power for A-side logic, OE input, and A-port drivers; must be ≤ VCC(B) in active mode |
| VCC(B) | B-port supply | Provides power for B-side logic and drivers; supports 5 V legacy interface compatibility |
| GND | Ground reference | Common return path for both supplies; thermal pad (terminal 1) is non-functional unless grounded |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXB0108PW-Q100 | TSSOP20 package (SOT360-1); no side-wettable flanks; higher thermal resistance (10.0 mW/K derating above 100 °C) | Suitable for prototyping or low-volume manual assembly; lacks AOI support for high-reliability automotive SMT lines | Select when board space allows larger footprint and AOI is not required. |
| NXS0108BQ-Q100 | Open-drain architecture with pull-up resistors; supports I²C and 1-Wire protocols; no auto-direction sensing | Required for true bidirectional open-drain buses; cannot replace NXB0108 in push-pull applications | Choose only for I²C/SMBus interfaces where bus arbitration and clock stretching are needed. |
Compared with NXB0108PW-Q100, the BQ variant offers superior thermal performance and AOI-compatible packaging for automated production; versus NXS0108BQ-Q100, it delivers faster push-pull signaling but lacks native I²C compatibility-making it optimal for high-speed parallel control links in AEC-Q100 systems.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) must never exceed VCC(B) during normal operation per datasheet Section 8, though transient overvoltage during power-up is tolerated. The absolute maximum rating allows VCC(A) up to +6.5 V and VCC(B) up to +6.5 V independently, but functional operation requires VCC(A) ≤ VCC(B) to prevent latch-up and ensure correct auto-direction sensing behavior.
Can NXB0108BQ-Q100 translate between 1.2 V and 5.0 V without external components?
Yes-NXB0108BQ-Q100 supports direct 1.2 V ↔ 5.0 V translation with VCC(A) = 1.2 V and VCC(B) = 5.0 V. Inputs on both sides accept up to 5.5 V, and the IOFF circuit ensures safe isolation during power sequencing. No pull-up resistors or direction-control logic are required due to its auto-sensing architecture.
Is the thermal pad (GND(1)) required to be soldered and connected to ground?
No-the thermal pad (terminal 1) has no electrical function per datasheet footnote (1). It may remain floating or be connected to GND if thermal performance demands it, but soldering is optional and grounding is not mandatory for electrical operation or AEC-Q100 compliance.
Does NXB0108BQ-Q100 support hot insertion or live swapping of supply rails?
It supports controlled hot insertion: either VCC(A) or VCC(B) may be ramped first during power-up without damage, and IOFF activation ensures outputs enter high-impedance state within microseconds if one rail collapses. However, sustained operation with VCC(A) > VCC(B) is prohibited and may cause undefined behavior or increased leakage.
