Product details
Overview
NXB0102DC-Q100 from Nexperia is a 2-bit automotive-qualified dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control. It operates with VCC(A) from 1.2 V to 3.6 V and VCC(B) from 1.65 V to 5.5 V, enabling translation between 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V domains. A single OE input (active HIGH, referenced to VCC(A)) controls high-impedance state, and IOFF circuitry ensures safe partial power-down in automotive ECUs.
For engineers reviewing the NXB0102DC-Q100 datasheet, NXB0102DC-Q100 pinout, NXB0102DC-Q100 application, or NXB0102DC-Q100 equivalent, key selection criteria include asymmetric supply tolerance (VCC(A) ≤ VCC(B)), auto-direction detection without external control signals, guaranteed operation from −40 °C to +125 °C, HBM ESD robustness (15 kV on B port), and dynamic performance up to 100 Mbps at 3.3 V/5.0 V.
Technical Context
The device implements edge-triggered one-shot circuitry on both A and B ports to detect data flow direction automatically-no external DIR signal required. Each channel uses weak static drivers combined with transient PMOS/NMOS boost transistors (T1–T4) activated during rising/falling edges to accelerate transitions while maintaining bus contention safety.
IOFF protection disables outputs when either VCC(A) or VCC(B) is unpowered, limiting backflow current to ±2 μA across temperature. Input thresholds are rail-proportional (VIH = 0.65×VCCI, VIL = 0.35×VCCI), and output drive strength scales with VCCO: typical impedance is 70 Ω (1.2–1.8 V), 50 Ω (1.8–3.3 V), or 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-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; supports legacy 5 V logic interfacing |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Data Rate | Up to 100 Mbps - achievable at VCC(A)=3.3 V / VCC(B)=5.0 V with 10 pF load |
| Propagation Delay | 0.8 ns (min) to 16.7 ns (max) - bidirectional, varies with supply and temperature |
| ESD Robustness | HBM Class 3B (15 kV) on B port - enables direct connection to exposed automotive interfaces |
| IOFF Leakage | ±2 μA max at +125 °C - prevents damaging back-current during system power sequencing |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102QPWRQ1 | Requires external DIR signal; no auto-direction sensing; higher ICC (15 μA vs. 8 μA typical) | Lacks autonomous bus arbitration; unsuitable for protocols with rapid direction reversal (e.g., I²C) | Select only if direction control is already available and lower cost outweighs added board routing complexity |
| SN74AVC2T244QDCURQ1 | Fixed-direction (A→B only); no B→A path; no IOFF; 1.65–3.6 V only on both sides | Cannot support bidirectional protocols like SPI or UART handshaking; limited voltage range | Use only for unidirectional signal isolation where VCC matching is strict and direction is static |
Compared with TXS0102QPWRQ1 and SN74AVC2T244QDCURQ1, NXB0102DC-Q100 uniquely delivers true bidirectional auto-sensing translation with full 1.2 V–5.5 V interoperability, IOFF safety, and AEC-Q100 Grade 1 compliance-making it the sole choice for next-generation automotive domain controllers requiring zero-latency bus arbitration.

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 7 and Table 9. The absolute maximum rating allows VCC(A) up to +6.5 V and VCC(B) up to +6.5 V individually, but functional operation requires VCC(A) ≤ VCC(B). During power-up, temporary VCC(A) > VCC(B) is tolerated without damage, eliminating strict sequencing requirements.
Can NXB0102DC-Q100 translate between 1.2 V and 5.0 V simultaneously?
Yes. With VCC(A) = 1.2 V and VCC(B) = 5.0 V, the device fully supports bidirectional translation: A-side I/Os operate at 1.2 V logic levels while B-side I/Os interface to 5.0 V systems. Input tolerance up to 5.5 V on both sides and rail-proportional thresholds ensure correct sampling across the full range.
Does the auto-direction sensing introduce latency or data corruption?
No. Direction detection occurs via nanosecond-scale edge-triggered one-shots that activate only during signal transitions. Static states maintain defined logic levels, and propagation delay (as low as 0.8 ns) is deterministic and specified across all voltage/temperature conditions-no metastability or bit errors are introduced.
How does IOFF protection behave when only VCC(B) is powered?
When VCC(B) is active and VCC(A) = 0 V, the B-side I/Os remain functional and driven, while A-side I/Os enter high-impedance with ±2 μA leakage (per Table 9). This allows safe "B-only" operation-e.g., sensor readout during MCU sleep-without risk of back-current through the unpowered A domain.
