Product details
Overview
NXB0101GW-Q100 from Nexperia is a 1-bit dual-supply auto-sensing bidirectional voltage-level translator IC, enabling seamless interface between 1.2 V–3.6 V and 1.65 V–5.5 V domains. It features independent A/B ports referenced to VCC(A) and VCC(B), active-HIGH OE control, and IOFF partial power-down protection. Used in automotive infotainment data buses for translating between 1.8 V microcontroller GPIOs and 3.3 V sensor interfaces.
For engineers reviewing the NXB0101GW-Q100 datasheet, NXB0101GW-Q100 pinout, NXB0101GW-Q100 application, or NXB0101GW-Q100 equivalent, key selection criteria include asymmetric supply range support (VCC(A): 1.2–3.6 V / VCC(B): 1.65–5.5 V), ±2 mA minimum input drive requirement, 70–40 Ω dynamic output impedance scaling with VCCO, and AEC-Q100 Grade 1 qualification for -40 °C to +125 °C operation.
Technical Context
The device implements auto-direction sensing via edge-triggered one-shot circuits on both A and B ports, eliminating external direction control signals. Each port uses weak static drivers (70 Ω at 1.2–1.8 V, 50 Ω at 1.8–3.3 V, 40 Ω at 3.3–5.0 V) that are overdriven during bus transitions, enabling true bidirectional translation without contention.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is powered down, limiting backflow current to ±2 μA across -40 °C to +125 °C. Input thresholds scale with respective supply voltages (VIH = 0.65 × VCCI; VIL = 0.35 × VCCI), ensuring robust noise margins across all supported voltage combinations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-port logic and OE; must be ≤ VCC(B) for safe operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-port logic; supports legacy 5 V and modern low-voltage systems |
| Propagation Delay | 0.8–12.9 ns (A↔B) - varies with VCC(A)/VCC(B); enables >40 Mbps data rate at full temp range |
| IOFF Leakage | ±2 μA max at -40 °C to +125 °C - prevents damaging backflow during partial power-down |
| ESD Rating | HBM: 2.5 kV (A port), 15 kV (B port) - protects against handling and system-level ESD events |
| Operating Temp | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Dynamic Output Impedance | 70 Ω (VCCO = 1.2–1.8 V), 50 Ω (1.8–3.3 V), 40 Ω (3.3–5.0 V) - ensures fast edge rates into typical PCB loads |
Pinout & Package
TSSOP6 plastic thin shrink small outline package (SOT363-2), 6-lead, body width 1.25 mm, 0.65 mm pitch, moisture sensitivity level 1 (MSL1).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-port logic and OE input; defines VIH/VIL thresholds for A/OE pins |
| 2 | GND | Common reference for both supply domains; required for IOFF and ESD clamp operation |
| 3 | A | Bidirectional I/O referenced to VCC(A); accepts inputs up to 5.5 V; drives A-side loads |
| 4 | B | Bidirectional I/O referenced to VCC(B); accepts inputs up to 5.5 V; drives B-side loads |
| 5 | OE | Active-HIGH output enable; referenced to VCC(A); LOW forces high-impedance OFF-state on A/B |
| 6 | VCC(B) | Supply for B-port logic; sets VOH/VOL levels and dynamic drive strength on B port |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Edge-triggered one-shot circuitry on A/B ports eliminates need for external DIR control signal |
| Asymmetric dual-supply operation | VCC(A) and VCC(B) independently set; supports 1.2 V ↔ 5.5 V translation without level-shifter chains |
| IOFF partial power-down | Prevents backflow current when either supply is off; maintains < ±2 μA leakage at +125 °C |
| High-BWM ESD protection | B port rated to 15 kV HBM (JS-001 Class 3B) - suitable for exposed automotive data lines |
| Temperature-stable timing | Propagation delay variation < ±3 ns across -40 °C to +125 °C at 3.3 V/5.0 V operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXB0101GS-Q100 | Same silicon die, XSON6 (SOT1202) package: 1.0 × 1.0 × 0.35 mm, no leads, higher thermal resistance | Preferred for ultra-dense PCB layouts where TSSOP6 footprint is prohibitive; requires reflow-compatible assembly | Select GS variant only when board space constraints outweigh thermal derating needs (Ptot derates at 3.3 mW/K above 74 °C vs. 3.7 mW/K for GW) |
| NXS0101UK-Q100 | Open-drain architecture with internal pull-ups; lacks auto-direction sensing; requires external DIR control | Suitable for I²C/SMBus where bus arbitration and pull-up topology are mandatory; not compatible with push-pull protocols | Choose NXS0101UK-Q100 only for true open-drain applications; NXB0101GW-Q100 is incompatible with I²C due to weak static drive and no internal pull-ups |
Compared with NXB0101GS-Q100, the GW variant offers better thermal performance in sustained 125 °C environments; compared with NXS0101UK-Q100, it delivers autonomous bidirectional operation but cannot replace open-drain bus architectures without redesigning pull-up networks.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) must never exceed VCC(B) during normal operation per datasheet Section 9. Violating this causes undefined behavior and potential latch-up. However, during power-up sequencing, VCC(A) ≥ VCC(B) is permitted and non-damaging due to internal protection circuitry. The absolute maximum rating for both supplies is -0.5 V to +6.5 V referenced to GND.
Can NXB0101GW-Q100 be used in I²C applications?
No - the NXB0101GW-Q100 is unsuitable for I²C due to its push-pull output architecture and lack of internal pull-ups. Its weak static drive strength (designed for capacitive loading ≤70 pF) cannot sustain I²C bus contention or meet open-drain timing requirements. For I²C, Nexperia recommends the NXS0101UK-Q100, which features integrated 10 kΩ pull-ups and open-drain outputs.
How does the auto-direction sensing circuit respond to simultaneous A/B transitions?
The one-shot circuits on A and B ports operate independently and detect edges with 1 ns/V input transition rate tolerance. Simultaneous rising/falling edges trigger both PMOS and NMOS acceleration paths concurrently, maintaining correct output polarity without bus contention. Propagation delay remains within spec (≤12.9 ns) even under worst-case skew conditions per Table 11.
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 reliable turn-off (guaranteeing OE < 0.35 × VCC(A) at startup) against excessive current draw (<350 μA at 3.6 V). Lower values increase power consumption; higher values risk slow turn-on if driven by high-impedance sources.
