Product details
Overview
NXB0104GU12-Q100 from Nexperia is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in XQFN12 package, supporting 1.2 V to 3.6 V on port A and 1.65 V to 5.5 V on port B, with 3-state output control via active-HIGH OE referenced to VCC(A), enabling seamless interface between automotive microcontrollers (e.g., 1.8 V CAN FD nodes) and 3.3 V/5.0 V sensors or actuators.
For engineers reviewing the NXB0104GU12-Q100 datasheet, NXB0104GU12-Q100 pinout, NXB0104GU12-Q100 application, or NXB0104GU12-Q100 equivalent, key selection criteria include verified IOFF-enabled partial power-down behavior, guaranteed ±2 μA max input leakage across −40 °C to +125 °C, documented 70 Mbps data rate at 5.0 V VCC(B), and confirmed side-wettable-flank-compatible XQFN12 footprint for AOI-capable automotive PCB assembly.
Technical Context
The device implements edge-triggered one-shot circuitry per I/O channel to accelerate transitions without external direction control: rising edges activate PMOS drivers (T1/T3), falling edges activate NMOS drivers (T2/T4), delivering typical output impedance of 40 Ω at VCCO = 3.3–5.0 V and 70 Ω at VCCO = 1.2–1.8 V. Each port operates independently under its own supply reference-An/OE tied to VCC(A), Bn to VCC(B)-with strict VCC(A) ≤ VCC(B) constraint enforced by internal architecture.
IOFF circuitry ensures safe partial power-down: when either VCC(A) or VCC(B) drops to GND, output clamping limits backflow current to ±2 μA max, satisfying automotive ASIL-B system-level fault containment requirements. The auto-direction sensing logic requires no external clock or control signal-data flow direction is determined solely by transient edge detection on A or B ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - supports direct interface with 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| VCC(B) Range | 1.65 V to 5.5 V - enables translation to legacy 3.3 V and 5.0 V automotive subsystems |
| Data Rate | 70 Mbps at VCC(B) = 5.0 V - sufficient for high-speed sensor data aggregation in ADAS ECUs |
| Propagation Delay | 4.9 ns (B→A) at VCC(A)=3.3 V / VCC(B)=5.0 V - ensures sub-5 ns timing margin for 100 MHz synchronous buses |
| IOFF Leakage | ±2 μA max at −40 °C to +125 °C - guarantees <100 nW standby power in powered-down domains |
| ESD Robustness | HBM 15 kV on B port, 2.5 kV on A port - meets ISO 10605 requirements for in-vehicle harness coupling immunity |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and transmission control modules |
Pinout & Package
XQFN12 package (SOT1174-1), 1.70 × 2.0 × 0.50 mm body, side-wettable flanks for automated optical inspection of solder joints; 12-terminal no-lead construction with exposed thermal pad (non-electrical, floating or GND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side I/Os and OE input - must be ≤ VCC(B); powers internal level-shifting logic |

| 6 | GND | Common reference plane for both supplies; required for IOFF clamp operation and ESD path |
| 7–10 | B1–B4 | Bidirectional data pins referenced to VCC(B); drive 5.0 V logic with 40 Ω typical output impedance |
| 11 | VCC(B) | Supply for B-side I/Os - sets VOH/VOL thresholds and output drive strength |
| 12 | OE | Active-HIGH output enable referenced to VCC(A); forces all A/B pins into high-Z when LOW |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E-Q1 | 4-bit, 1.65–3.6 V A-side / 2.3–5.5 V B-side; no IOFF; 14-pin TSSOP only | Lacks AEC-Q100 Grade 1 rating; max temp +85 °C; unsuitable for engine bay placement | Select only for non-automotive industrial use where partial power-down is not required. |
| NXB0104BQ-Q100 | Same core functionality but DHVQFN14 (2.5 × 3 × 0.85 mm); higher Ptot (500 mW vs 250 mW) | Larger footprint and thermal mass; better for high-duty-cycle data bursts but less space-constrained | Choose when board layout allows larger package and thermal dissipation >250 mW is needed. |
Compared with TXS0104E-Q1, NXB0104GU12-Q100 delivers certified automotive reliability and true partial power-down; versus NXB0104BQ-Q100, it trades thermal headroom for 30 % smaller area and AOI-ready side-wettable flanks-critical for compact ADAS modules.

FAQ
What is the minimum allowed voltage difference between VCC(A) and VCC(B)?
VCC(A) must be ≤ VCC(B) per datasheet Section 7 and Table 6, but no minimum difference is specified. Operation is validated down to VCC(A) = 1.2 V and VCC(B) = 1.65 V (0.45 V delta), with full functionality including IOFF and auto-direction sensing maintained across this range.
Can OE be driven from a 3.3 V microcontroller when VCC(A) = 1.2 V?
No-OE is referenced strictly to VCC(A), so its valid HIGH threshold is 0.65 × VCC(A) min (0.78 V at 1.2 V). A 3.3 V GPIO would exceed absolute maximum rating of +6.5 V but more critically violate VIH specification; OE must be driven from a 1.2 V–3.6 V source synchronized to VCC(A).
Does the device support hot-swapping between live voltage domains?
Yes-IOFF circuitry actively disables outputs and limits leakage to ±2 μA when either supply collapses, preventing back-current damage. This enables safe insertion/removal of modules powered by independent rails, such as adding a new sensor node to an active CAN backbone.
How does the one-shot architecture affect signal integrity on long traces?
The one-shot pulse duration (~8–15 ns) requires round-trip reflection delay to stay within that window. For FR-4 PCBs (150 ps/in), trace length must remain under ~2.5 inches; longer runs risk re-triggering and oscillation-hence design guidance mandates short traces and low-capacitance connectors.
