Product details
Overview
NXB0106BQX from Nexperia is a 6-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control. It enables seamless interface between 1.2 V–3.6 V (A-side) and 1.65 V–5.5 V (B-side) domains, supports ±2 mA input drive, features IOFF partial power-down protection, and operates across −40 °C to +125 °C. It is used in mixed-voltage system interconnects such as FPGA-to-ASIC data buses.
For engineers reviewing the NXB0106BQX datasheet, NXB0106BQX pinout, NXB0106BQX application, or NXB0106BQX equivalent, key selection criteria include its auto-direction architecture (no external DIR signal), asymmetric supply range compatibility (VCC(A) ≤ VCC(B)), IOFF-enabled safe power sequencing, and 60 Mbps data rate at 3.3 V/1.8 V operation.
Technical Context
The NXB0106BQX implements edge-detecting one-shot circuits on both A and B ports to automatically enable the correct direction path without external control logic. Its I/O cells use weak static drivers (70 Ω typical at 1.2–1.8 V, 40 Ω at 3.3–5.0 V) that are overdriven by bus traffic, enabling true bidirectional translation.
It incorporates dedicated IOFF circuitry that disables outputs and limits backflow current when either VCC(A) or VCC(B) is powered down, satisfying JEDEC JESD78B Class II latch-up immunity (>100 mA) and supporting hot-swap-capable system designs.
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) for safe operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/Os; enables translation to legacy 5 V logic |
| Data Rate | 60 Mbps at 25 °C (1.8 V/3.3 V) - supports high-speed serial interconnects like GPIO expansion links |
| Propagation Delay | 4.9–7.1 ns (A↔B) - ensures timing-critical synchronization in real-time control loops |
| IOFF Leakage | ±2 μA max at −40 °C to +125 °C - prevents damaging back-current during asymmetric power-down |
| ESD Robustness | HBM 15 kV (B port), 2.5 kV (A port); CDM 1.5 kV - sustains handling and board-level ESD events |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive and industrial motor-control environments |
Pinout & Package
DHVQFN16 (SOT763-1) package: 2.5 × 3.5 × 0.85 mm body, 16-terminal no-lead thermal-enhanced quad flat; exposed thermal pad (non-grounded, optional GND connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A6 | A-side bidirectional data I/O | Referenced to VCC(A); accept inputs up to 5.5 V; drive 1.2–3.6 V logic levels |
| B1–B6 | B-side bidirectional data I/O | Referenced to VCC(B); tolerate 0–5.5 V; translate to/from 1.65–5.5 V domains |
| OE | Output enable (active HIGH) | Referenced to VCC(A); forces all I/Os into high-impedance state when LOW |
| VCC(A) | A-side supply rail | Powers A-port logic and OE input; must be ≤ VCC(B) during active operation |
| VCC(B) | B-side supply rail | Powers B-port logic; enables 5 V-tolerant interface capability |
| GND | Common reference ground | Single ground plane required; IOFF protection activates if either VCC floats |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal, reducing PCB routing and MCU GPIO count |
| Asymmetric supply support | VCC(A) = 1.2–3.6 V, VCC(B) = 1.65–5.5 V - enables direct interfacing of ultra-low-power sensors to 5 V microcontrollers |
| IOFF partial power-down | Prevents backflow current when either supply is off - critical for modular hot-plug systems |
| High ESD tolerance (B port) | 15 kV HBM - protects against field-induced discharge in industrial I/O modules |
| Low dynamic power dissipation | CPD = 7.0–28.7 pF depending on direction and supply - minimizes switching losses in battery-powered gateways |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0108E | 8-bit, 1.65–5.5 V on both sides; no VCC(A)/VCC(B) asymmetry; requires external DIR | Lacks auto-direction sensing; needs MCU GPIO for direction control | Select when fixed 8-bit width and symmetric rails suffice; avoid where A/B voltage mismatch exists |
| NXS0106 | Open-drain compatible; supports I²C/1-Wire; lower drive strength; no IOFF | Designed for multi-master open-drain buses; not suitable for push-pull applications | Choose only for I²C/SMBus translation; reject for general-purpose push-pull GPIO translation |
Compared with TXS0108E and NXS0106, the NXB0106BQX uniquely combines asymmetric dual-supply operation, auto-direction sensing, and IOFF protection - making it the only option for robust, GPIO-efficient, hot-pluggable mixed-voltage interconnects requiring no direction control overhead.

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. This constraint ensures internal clamp diodes remain reverse-biased and prevents latch-up. During power-up, however, VCC(A) may transiently exceed VCC(B) without damage - no sequencing is required.
Can NXB0106BQX be used in I²C applications?
No - the NXB0106BQX is not suitable for I²C. Its push-pull outputs and minimum 50 kΩ pull-up requirement conflict with I²C's open-drain topology and standard 2.2–10 kΩ pull-ups. The NXS0106 is Nexperia's designated alternative for I²C and 1-Wire protocols.
How does the auto-direction sensing mechanism work without external control?
Each I/O channel contains edge-detecting one-shot circuits that monitor rising/falling edges on A or B pins. Upon detecting activity, the corresponding PMOS/NMOS driver pair is briefly enabled to accelerate the transition, allowing automatic flow direction determination without a DIR pin or firmware intervention.
What is the recommended OE pull-down resistor value during power-up?
A 10 kΩ pull-down resistor on OE is recommended to ensure high-impedance state at power-on. This value balances leakage current (≤2 μA) and noise immunity while remaining compatible with typical MCU GPIO sink capabilities (≥4 mA). Values below 5 kΩ risk excessive current draw during OE assertion.
