Product details
Overview
NXB0101 from Nexperia is a 1-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver with 3-state output control, enabling seamless interfacing 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 input referenced to VCC(A), and IOFF circuitry for partial power-down protection. 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 criteria include asymmetric supply range support (VCC(A): 1.2–3.6 V / VCC(B): 1.65–5.5 V), auto-direction sensing without external control, guaranteed 40 Mbps data rate at 3.3 V/5.0 V, and ±1 μA off-state leakage across −40 °C to +125 °C.
Technical Context
The NXB0101 implements edge-triggered one-shot circuitry on both A and B ports to autonomously detect data flow direction-rising edges activate PMOS drivers, falling edges activate NMOS drivers-enabling true bidirectional translation without direction-control pins. Its IOFF architecture disables outputs during power-down, blocking backflow current when either supply is inactive.
Each port operates with supply-referenced I/O thresholds: VIH/VIL scale as 0.65×VCCI and 0.35×VCCI respectively, ensuring robust noise margins across all supported voltage combinations. Output drive strength is dynamically adjusted per VCCO: typical impedance is 70 Ω (1.2–1.8 V), 50 Ω (1.8–3.3 V), and 40 Ω (3.3–5.0 V).
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; sets VIH/VIL thresholds for A-side signals |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-port logic and output drivers; defines VOH/VOL compliance for B-side loads |
| Max Data Rate | 100 Mbps - achievable at VCC(A)=3.3 V / VCC(B)=5.0 V with 10 pF load; enables high-speed GPIO bridging |
| Propagation Delay | 0.8–12.9 ns - A→B and B→A paths vary with supply pair and temperature; critical for timing-critical bus arbitration |
| IOFF Leakage | ±2 μA max at −40 °C to +125 °C - prevents damaging current flow when either supply is off, satisfying IEC 61000-4-2 system-level ESD immunity requirements |
| ESD Robustness | HBM 15 kV on B port, 2.5 kV on A port - allows direct connection to exposed connectors in industrial HMI and automotive body control modules |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive applications without derating |
Pinout & Package
Available in three compact packages: TSSOP6 (SOT363-2), XSON6 (SOT886), and ultra-thin XSON6 (SOT1202). All variants share identical 6-pin functional mapping and thermal performance envelope.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | A-side supply rail | References A port I/O thresholds and OE input; must be ≤ VCC(B) during operation |
| GND | Common ground reference | Single ground plane required; no separate analog/digital GND pins |
| A | Bidirectional data port (A-side) | 1.2–3.6 V domain I/O; accepts up to 5.5 V inputs safely due to clamping structure |
| B | Bidirectional data port (B-side) | 1.65–5.5 V domain I/O; drives loads up to 50 mA peak with 40 Ω typical output impedance at 5 V |
| OE | Output enable (active HIGH) | Referenced to VCC(A); forces A/B into high-Z when LOW; requires pull-down for power-up safety |
| VCC(B) | B-side supply rail | References B port I/O thresholds and output drive strength; enables 5 V tolerant operation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signal; reduces PCB routing complexity and MCU GPIO count in bidirectional UART/SPI bridges |
| Asymmetric supply support | Enables direct interfacing between legacy 5 V peripherals and modern 1.2 V/1.8 V SoCs without level-shifter ICs or discrete MOSFET solutions |
| IOFF partial power-down | Prevents back-current when VCC(A) or VCC(B) is unpowered-critical for hot-plug USB-C accessories and modular industrial I/O cards |
| High-speed 100 Mbps capability | Supports real-time sensor fusion in automotive ADAS ECUs where 3.3 V camera links interface with 1.2 V vision processors |
| −40 °C to +125 °C operation | Validated for engine control units and battery management systems requiring extended temperature reliability without external thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-supply (VCCA only); requires external pull-up on B side; no IOFF; max 6 V on B port | Limited to 3.3 V ↔ 5 V use cases; unsuitable for partial-power-down systems | Select when cost sensitivity outweighs power-down safety and 1.2 V domain support |
| NXS0101GM | Open-drain architecture; supports I²C/1-Wire; no auto-direction; requires external pull-ups | Designed specifically for multi-master bus protocols; lacks push-pull drive for high-speed GPIO | Choose for I²C/SMBus isolation where bidirectional auto-sensing is unnecessary |
Compared with TXS0101DCKR and NXS0101GM, the NXB0101 uniquely combines dual-supply flexibility, true auto-direction sensing, and IOFF protection-making it the only option for robust, high-speed, mixed-voltage GPIO bridging in automotive and industrial power-gated systems.

FAQ
What is the minimum recommended pull-down resistor value for the OE pin?
The OE pin must be pulled to GND via a resistor to ensure high-impedance state during power-up. Based on the 20 μA maximum ICC(A) at VCC(A) = 3.6 V and OE = LOW, a 100 kΩ resistor limits leakage to 36 μW while guaranteeing reliable disable. Lower values increase power but improve noise immunity in noisy environments.
Can NXB0101 translate between 1.2 V and 5.0 V without external components?
Yes. With VCC(A) = 1.2 V and VCC(B) = 5.0 V, the device fully supports bidirectional translation: A port accepts 0–1.2 V logic and presents 0–5.0 V outputs on B, while B port tolerates 0–5.5 V inputs and drives 0–1.2 V levels on A-all without external resistors, diodes, or MOSFETs.
Does NXB0101 support hot-plug operation when VCC(B) is powered before VCC(A)?
Yes. The datasheet explicitly states that VCC(A) ≥ VCC(B) during power-up does not damage the device. IOFF circuitry activates as soon as either supply reaches ~0.8 V, preventing contention or latch-up-enabling safe hot-plug insertion into live 5 V backplanes.
Why is NXB0101 not recommended for I²C applications?
The NXB0101 uses push-pull outputs with low static drive strength (~70 Ω), which conflicts with I²C's open-drain requirement. Pull-up resistors below 50 kΩ cause contention; higher values fail to meet rise-time specs. Nexperia recommends NXS0101-a dedicated open-drain translator-for I²C, SMBus, and 1-Wire protocols.
