Product details
Overview
NXB0108PW-Q100 from Nexperia is an 8-bit dual-supply auto-sensing bidirectional voltage-level transceiver with independent A- and B-side supplies (VCC(A): 1.2–3.6 V; VCC(B): 1.65–5.5 V), 3-state output control via active-HIGH OE, and IOFF partial power-down protection. It enables seamless interfacing between 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V and 5.0 V domains in automotive infotainment and ADAS domain controllers.
For engineers reviewing the NXB0108PW-Q100 datasheet, NXB0108PW-Q100 pinout, NXB0108PW-Q100 application, or NXB0108PW-Q100 equivalent, key selection criteria include asymmetric supply tolerance (VCC(A) ≤ VCC(B)), ±2 mA minimum input drive requirement, 40–70 Ω dynamic output impedance across voltage ranges, and AEC-Q100 Grade 1 qualification for −40 °C to +125 °C operation.
Technical Context
The device implements auto-direction sensing using edge-triggered one-shot circuits on each I/O pair - rising edges activate PMOS drivers (T1/T3), falling edges activate NMOS drivers (T2/T4) - eliminating external direction control. Its weak-output architecture allows bus contention resolution without external arbitration logic.
IOFF circuitry ensures zero backflow current when either VCC(A) or VCC(B) is at GND, enabling safe partial power-down in multi-rail systems. Input clamping supports up to 5.5 V on both ports regardless of supply state, and static leakage remains ≤ ±10 μA over full temperature range.
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 logic domains as A-side reference |
| VCC(B) Range | 1.65 V to 5.5 V - enables translation to 1.8 V/2.5 V/3.3 V/5.0 V systems on B side |
| Propagation Delay | 0.8–11.9 ns (A↔B) - guarantees sub-12 ns latency at worst-case −40 °C/+125 °C, 1.5 V/1.8 V |
| Data Rate | Up to 110 Mbps - validated at 3.3 V/5.0 V with 10 ns pulse width margin |
| ESD Rating | HBM: 2.5 kV (A port), 15 kV (B port); CDM: 1.5 kV - exceeds AEC-Q100 stress requirements |
| IOFF Leakage | ≤ ±10 μA at −40 °C to +125 °C - prevents cross-rail current during asymmetric power sequencing |
| Output Skew | ≤ 2.6 ns max (−40 °C to +125 °C) - ensures deterministic timing across all 8 channels |
Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | A-side bidirectional data I/O | Referenced to VCC(A); accept 0–5.5 V inputs; drive A-port loads up to 70 pF |
| B1–B8 | B-side bidirectional data I/O | Referenced to VCC(B); tolerate 0–5.5 V; support 5.0 V-tolerant interface without level shifters |
| OE | Active-HIGH output enable | Asserted HIGH enables auto-direction translation; LOW forces all I/Os into high-Z state |
| VCC(A) | A-side supply rail | Must be ≤ VCC(B); powers internal logic and A-port drivers; IOFF disables outputs if VCC(A) = 0 V |
| VCC(B) | B-side supply rail | Enables B-port output strength scaling; IOFF also activates if VCC(B) = 0 V |
| GND | Common reference ground | Single ground plane required; no separate analog/digital grounds needed |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external DIR signal or microcontroller GPIO coordination in bidirectional buses |
| Asymmetric supply support | VCC(A) ≤ VCC(B) constraint enables robust 1.2 V ↔ 5.0 V translation without external biasing |
| IOFF partial power-down | Prevents damaging back-current when only one supply is active - critical for domain-isolated automotive ECUs |
| High-voltage tolerant inputs | Accepts 0–5.5 V on all I/O pins regardless of VCC(A)/VCC(B) state - simplifies mixed-voltage board routing |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - meets ASIL-B system-level thermal requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXB0108BQ-Q100 | DHVQFN20 package (2.5 × 4.5 × 0.85 mm); same electrical specs; enhanced thermal performance (12.9 mW/K derating above 111 °C) | Better suited for space-constrained, thermally dense modules like radar front-ends | Select when PCB area is limited and junction temperature exceeds 100 °C under continuous load |
| NXS0108-Q100 | Open-drain architecture; supports I²C, SMBus, 1-Wire; no auto-direction sensing; requires external pull-ups | Designed for true open-drain protocols where bus contention must be avoided at all times | Choose only for I²C/SMBus applications - NXB0108PW-Q100 is incompatible due to push-pull output structure |
Compared with NXB0108BQ-Q100, the PW variant offers easier TSSOP rework and AOI compatibility but lower thermal efficiency; versus NXS0108-Q100, it delivers higher speed and push-pull drive but cannot replace open-drain buses without redesign.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) must not exceed VCC(B) under any operating condition per datasheet Section 8 Note [2]. The absolute maximum ratings allow both supplies up to +6.5 V, but functional operation requires VCC(A) ≤ VCC(B). During power-up, transient violation is tolerated, but sustained overvoltage risks latch-up or accelerated wear-out.
Can NXB0108PW-Q100 be used in I²C applications?
No - its push-pull output architecture causes bus contention in open-drain I²C topologies. The device lacks built-in wired-AND behavior and cannot safely share a bidirectional SDA line without external isolation. For I²C, Nexperia specifies NXS0108-Q100, which uses true open-drain outputs with integrated current limiting.
How does the auto-direction sensing circuit handle simultaneous A→B and B→A transitions?
The one-shot edge detectors operate independently per channel. Simultaneous transitions trigger both PMOS and NMOS drivers briefly, resulting in brief shoot-through current (<10 ns). The architecture tolerates this per Figure 6 and Table 12 CPD measurements, with total power dissipation remaining within 500 mW limit at rated temperatures.
Is external pull-up resistance required on A or B ports?
No external pull-ups are required or recommended. The device drives actively in both directions and supports capacitive loads up to 70 pF. Pull-up resistors <50 kΩ cause contention and violate the ±2 mA input drive requirement; values ≥50 kΩ introduce unacceptable rise-time degradation per Section 11.6.
