Product details
Overview
NXB0101 from Nexperia is a 1-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control. It enables seamless interfacing between 1.2 V–3.6 V logic domains (A side) and 1.65 V–5.5 V domains (B side), supports partial power-down via IOFF, and operates across −40 °C to +125 °C. Used in mixed-voltage microcontroller I/O expansion and FPGA-to-peripheral bridging.
For engineers reviewing the NXB0101 datasheet, NXB0101 pinout, NXB0101 application, or NXB0101 equivalent, this page delivers verified electrical specs, validated package mapping (XSON6/SOT886), confirmed auto-sensing behavior, and real-world level-shifting design constraints - all extracted from Nexperia's Rev. 5 product data sheet (Nov 2023).
Technical Context
The NXB0101 implements edge-triggered one-shot circuitry on both A and B ports to detect signal direction automatically-no external direction control line required. Its dual-rail architecture isolates VCC(A) and VCC(B), with OE referenced to VCC(A) and I/Os referenced to their respective supplies.
IOFF protection disables outputs during partial power-down, limiting backflow current when either supply is off. Input clamping accepts up to 5.5 V on B-side pins regardless of VCC(B), and static drive strength is intentionally weak (70 Ω typical at low VCCO) to enable bus contention resolution without external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side logic and OE input; must be ≤ VCC(B) during operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/O; enables translation to 5 V systems |
| Propagation Delay (A→B) | 0.8 ns to 15.9 ns - varies with supply pair and temperature; min 0.8 ns at 3.3 V/5.0 V, −40 °C to +125 °C |
| Data Rate | Up to 100 Mbps - supported at VCC(A)=3.3 V/VCC(B)=5.0 V within −40 °C to +125 °C |
| IOFF Leakage | ±2 μA max - ensures safe isolation when either supply is powered down |
| ESD Rating (B port) | HBM >15 kV - meets JS-001 Class 3B for robustness in handling-sensitive applications |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
Package: XSON6 (SOT886), plastic extremely thin small outline package, 1.0 × 1.45 × 0.5 mm, no leads, 6 terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VCC(A) | A-side supply rail | Powers A-port I/O and OE input; sets VIH/VIL thresholds for A and OE |
| 2: GND | Common reference | Ground return for both supply domains; required for IOFF and ESD path integrity |
| 3: A | Bidirectional data port (A side) | Referenced to VCC(A); accepts 0–3.6 V inputs; drives 0–VCC(A) outputs |
| 4: B | Bidirectional data port (B side) | Referenced to VCC(B); accepts 0–5.5 V inputs; drives 0–VCC(B) outputs |
| 5: OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces A/B into high-impedance OFF-state |
| 6: VCC(B) | B-side supply rail | Powers B-port I/O; must be ≥ VCC(A) during active operation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Edge-detecting one-shot circuitry eliminates need for external DIR control line in bidirectional buses |
| Dual independent supply rails | VCC(A) and VCC(B) operate independently - enables translation between 1.2 V MCU and 5 V sensor interface |
| IOFF partial power-down | Prevents damaging backflow current when either supply is off; leakage ≤ ±2 μA at −40 °C to +125 °C |
| High B-port ESD immunity | HBM >15 kV on B port - protects against handling damage in manufacturing and field service |
| Low dynamic power dissipation | CPD as low as 0.05 pF (A port, disabled state) - reduces switching noise and system-level power budget impact |
Applications
| Microcontroller I/O Expansion | FPGA-to-Peripheral Bridging |
|---|---|
|

IC Role / Device Role / Timing Role: Level-shifting transceiver operating across −40 °C to +125 °C with IOFF for sleep-mode isolation. Use Value: Enables zero-current leakage during vehicle sleep mode (IOFF < ±2 μA), meeting ISO 16750-2 quiescent current requirements. |
Use Scenario: Aggregating multiple analog sensors (1.2 V, 1.8 V, 3.3 V) into a single 5 V data acquisition unit in factory automation. IC Role / Device Role / Timing Role: Multi-voltage domain translator supporting hot-plug detection and fault-isolated communication paths. Use Value: Supports simultaneous translation across 1.2 V → 5.0 V, 1.8 V → 5.0 V, and 3.3 V → 5.0 V pairs using one device per channel - simplifies layout and thermal management. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-channel, 1.65–5.5 V VCCA/VCCB; no IOFF; lower ESD (HBM 8 kV B port) | Lacks partial power-down; unsuitable for automotive sleep-mode isolation | Select when IOFF and >15 kV ESD are not required; lower cost but higher system-level risk in powered-down states |
| NXS0101GMX | Open-drain compatible; supports I²C/1-Wire; weaker drive (10 mA vs 50 mA); no auto-direction sensing | Requires external pull-ups; cannot replace NXB0101 in push-pull bus applications like SPI | Choose only for open-drain protocols; incompatible for auto-sensing push-pull use cases due to missing one-shot architecture |
Compared with TXS0101DCKR and NXS0101GMX, NXB0101 uniquely combines auto-direction sensing, IOFF-enabled partial power-down, and 15 kV HBM B-port ESD - making it the sole option for robust, low-leakage, direction-agnostic translation in automotive and industrial hot-swap environments.

FAQ
Can NXB0101 translate between 1.2 V and 5.0 V logic domains?
Yes. VCC(A) supports 1.2 V–3.6 V and VCC(B) supports 1.65 V–5.5 V, with the constraint that VCC(A) ≤ VCC(B) during operation. The device has been characterized for 1.2 V ↔ 5.0 V translation at −40 °C to +125 °C, delivering 100 Mbps data rate and maintaining VOH/VOL margins per JEDEC standards.
Is external direction control required for bidirectional operation?
No. NXB0101 uses internal edge-detecting one-shot circuitry on both A and B ports to sense signal direction automatically. No external DIR pin or control logic is needed - the device self-configures drive direction based on input edge transitions, enabling true plug-and-play bidirectional translation.
What happens if VCC(A) exceeds VCC(B) during power-up?
No damage occurs. While VCC(A) must not exceed VCC(B) during normal operation, the datasheet explicitly states that either supply may ramp first during power-up. Internal protection circuitry ensures safe startup, and IOFF activates automatically if either supply drops below operational threshold during runtime.
Why is NXB0101 not recommended for I²C applications?
Because its weak static drive strength (designed for bus contention resolution) and lack of open-drain compatibility conflict with I²C's wired-AND topology. Pull-up resistors <50 kΩ cause contention; the NXS0101 is specified for I²C/1-Wire. NXB0101 is optimized for push-pull buses like SPI, UART, and parallel control lines.
