Product details
Overview
NXB0101 from Nexperia is a 1-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver enabling seamless interface between 1.2 V–3.6 V and 1.65 V–5.5 V domains. It features independent VCC(A) and VCC(B) supplies, active HIGH OE control, IOFF partial power-down protection, and operates across −40 °C to +125 °C. Used in mixed-voltage microcontroller I/O expansion and sensor interface subsystems.
For engineers reviewing the NXB0101 datasheet, NXB0101 pinout, NXB0101 application, or NXB0101 equivalent, key selection considerations include asymmetric supply range compatibility (VCC(A) ≤ VCC(B)), auto-direction sensing without external control, 3-state output enable timing (ten ≤ 1.0 μs, tdis ≤ 155 ns), and ESD robustness (15 kV HBM on B port).
Technical Context
The NXB0101 implements edge-triggered one-shot circuitry on both A and B ports to autonomously detect data flow direction-rising/falling edges activate PMOS/NMOS boost transistors for accelerated transitions. Its weak static drive (70 Ω typical at 1.2–1.8 V VCCO) allows bus contention-free overdriving during direction reversal.
IOFF circuitry disables outputs when either supply is powered down, limiting backflow current to ±10 μA across −40 °C to +125 °C. Input thresholds track VCCI (VIH = 0.65 × VCCI, VIL = 0.35 × VCCI), and output levels comply with VOH ≥ VCCO − 0.4 V / VOL ≤ 0.4 V under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-port logic and OE input; must be ≤ VCC(B) for safe operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-port logic and output drivers; supports legacy 5 V and modern low-V systems |
| Propagation Delay | 0.8–15.9 ns - A↔B delay varies with supply pair (e.g., 0.8 ns @ 3.3 V/5.0 V, 15.9 ns @ 1.5 V/1.8 V) |
| Enable/Disable Time | ten ≤ 1.0 μs, tdis ≤ 155 ns - defines minimum OE assertion/deassertion window before valid I/O state |
| ESD Rating | HBM: 2.5 kV (A), 15 kV (B); CDM: 1.5 kV - enables direct connection to high-ESD-risk interfaces like USB or GPIO exposed to handling |
| IOFF Leakage | ±10 μA max - ensures <100 μW standby dissipation during partial power-down, critical for battery-backed systems |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments |
Pinout & Package
TSSOP6 (SOT363-2) package: plastic thin shrink small outline, 6-lead, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side logic and OE input; sets VIH/VIL thresholds and output swing reference for A port |
| 2 | GND | Common ground reference for all internal circuitry and signal return path |
| 3 | A | Bidirectional I/O referenced to VCC(A); accepts inputs up to 5.5 V and drives outputs to VCC(A) rail |
| 4 | B | Bidirectional I/O referenced to VCC(B); accepts inputs up to 5.5 V and drives outputs to VCC(B) rail |
| 5 | OE | Active HIGH output enable; LOW forces A/B into high-impedance OFF-state; referenced to VCC(A) |
| 6 | VCC(B) | Supply for B-side logic and output drivers; must be ≥ VCC(A) for functional translation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction control signals-edge detection on A or B triggers internal one-shot boost circuits |
| Dual independent supplies | VCC(A) and VCC(B) operate independently within specified ranges, enabling translation between 1.2 V MCU and 5 V peripheral |
| IOFF partial power-down | Prevents damaging back-current when either supply is off; maintains <±10 μA leakage at full temperature range |
| High-BWM ESD protection | 15 kV HBM on B port meets IEC 61000-4-2 Level 4 for system-level surge immunity in industrial interfaces |
| Wide temperature operation | Specified from −40 °C to +125 °C-supports automotive engine control units and industrial PLC I/O modules |
Applications
| Microcontroller I/O Expansion | Sensor Interface Subsystem |
|---|---|
Use Scenario: Connecting a 1.8 V ARM Cortex-M0+ MCU GPIO bank to a 3.3 V SPI flash memory. IC Role / Device Role / Timing Role: Bidirectional level translator enabling full-duplex SPI clock/data transfer without direction control overhead. Use Value: Eliminates need for discrete MOSFET translators or direction pins, reducing PCB area by >40% and simplifying firmware GPIO management. | Use Scenario: Interfacing a 2.5 V analog sensor ADC output to a 5.0 V industrial PLC digital input module. IC Role / Device Role / Timing Role: Unidirectional (sensor→PLC) voltage translator with auto-sensing fallback for reverse diagnostics. Use Value: Supports hot-plug sensor replacement without power cycling PLC; IOFF prevents backfeed into powered-down sensor during maintenance. |
| Automotive Body Control Module | Industrial Serial Bus Bridge |
Use Scenario: Linking a 3.3 V CAN controller to a 5.0 V LIN transceiver in a vehicle door module. IC Role / Device Role / Timing Role: Voltage translator for shared diagnostic bus lines operating across two power domains. Use Value: Enables single-wire bidirectional diagnostics (UDS over LIN) while maintaining ASIL-B compatible supply isolation and ESD resilience. | Use Scenario: Bridging RS-485 (3.3 V PHY) and Modbus RTU (5 V logic) in factory automation gateways. IC Role / Device Role / Timing Role: Level-shifting transceiver for half-duplex serial data lines with automatic direction arbitration. Use Value: Removes external direction control logic and reduces propagation delay skew vs. discrete solutions-critical for deterministic 100 kbps Modbus timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | Requires external pull-up resistors on both sides; no IOFF; lower ESD (8 kV HBM B port) | Limited to 3.3 V/5 V only; not rated for 1.2 V A-side operation | Select when cost sensitivity outweighs need for ultra-low-V support or partial power-down |
| NXS0101GW | Open-drain architecture; requires external pull-ups; optimized for I²C; lacks auto-direction sensing | Designed specifically for SMBus/I²C clock stretching; unsuitable for general-purpose GPIO translation | Choose only for I²C/SMBus applications where bus arbitration and clock stretching are required |
Compared with TXS0102DCUR and NXS0101GW, the NXB0101 uniquely supports 1.2 V A-side operation, integrates IOFF for true partial power-down, and delivers higher B-port ESD immunity-making it optimal for mixed-voltage embedded systems requiring robustness and minimal external components.

FAQ
Can NXB0101 translate between 1.2 V and 5.0 V domains?
Yes. VCC(A) supports 1.2 V to 3.6 V and VCC(B) supports 1.65 V to 5.5 V, with the constraint that VCC(A) ≤ VCC(B). This enables direct 1.2 V ↔ 5.0 V translation-verified in Table 9 (VIH/VIL tracking) and Table 11 (tpd at 1.2 V/5.0 V).
What happens if VCC(A) exceeds VCC(B) during normal operation?
VCC(A) must never exceed VCC(B) during active operation per Section 7 function table and Section 9 recommended conditions. Exceeding this violates absolute maximum ratings and may cause latch-up or permanent damage-power sequencing is unrestricted only during startup.
Is NXB0101 suitable for I²C bus level translation?
No. The NXB0101 has push-pull outputs and lacks open-drain behavior required for I²C wired-AND operation. Section 12.7 explicitly recommends NXS0101 for I²C. Using NXB0101 on I²C risks bus contention and protocol failure due to active drive during SCL/SDA low periods.
How does the auto-direction sensing work without external control?
Internal one-shot circuits monitor rising/falling edges on A or B ports. A detected edge activates PMOS (low-to-high) or NMOS (high-to-low) boost transistors for ~10 ns, accelerating transitions while allowing external drivers to override the weak static output-enabling true bidirectional arbitration without direction pins.
