Product details
Overview
NXU0104GU12-Q100 from Nexperia is a 4-bit unidirectional dual-supply voltage level translating buffer with Schmitt-trigger inputs, 3-state outputs, and AEC-Q100 Grade 1 automotive qualification. It translates signals from A-side (VCCA = 0.9–5.5 V) to B-side (VCCB = 0.9–5.5 V), supports up to 250 Mbps data rate at ≥1.8 V translation, features integrated 6.5 MΩ pull-down resistors on inputs, and enables bus isolation via OE pin referenced to either supply domain. It is used in automotive UART/SPI/JTAG interconnects between mixed-voltage subsystems.
For engineers reviewing the NXU0104GU12-Q100 datasheet, NXU0104GU12-Q100 pinout, NXU0104GU12-Q100 application, or NXU0104GU12-Q100 equivalent, key selection criteria include dual-supply translation range, Schmitt-trigger noise immunity for slow/noisy inputs, IOFF-enabled partial power-down safety, suspend-mode behavior during supply loss, and XQFN12 package compatibility with automated optical inspection (AOI).
Technical Context
This device implements fixed-direction (A→B) level translation using independent VCCA and VCCB rails, with Schmitt-trigger input thresholds (VT+ and VT−) providing hysteresis for noise rejection. The OE pin operates referenced to either supply domain via internal VCC(MIN) circuitry, enabling robust enable/disable control across voltage domains without external level shifters.
IOFF protection activates when either VCCA or VCCB drops below 100 mV or floats, forcing all YBn outputs into high-impedance state and blocking backflow current. No power-supply sequencing is required, and output glitches are suppressed during power-up/down transitions due to synchronized internal state management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCCA and VCCB independently support 0.9 V to 5.5 V - enables translation between 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V/5.0 V nodes |
| Max Data Rate | 250 Mbps (≥1.8 V to 5 V translation) - supports high-speed UART, SPI, and JTAG interfaces |
| Input Threshold Hysteresis | VH = 0.69–1.18 V (typical, VCCA = VCCB = 5.5 V) - ensures reliable switching under noisy or slow-rising input conditions |
| IOFF Leakage | ±2 μA max (VCCA or VCCB = 0 V or floating) - prevents damaging backflow current during partial power-down |
| Propagation Delay | 38.5–39.4 ns (VCCA = VCCB = 2.5–5.0 V) - guarantees deterministic timing in real-time automotive communication paths |
| ESD Rating | HBM ±2500 V, CDM ±1500 V - meets automotive-grade robustness requirements per JS-001/JS-002 |
| Operating Temp | −40 °C to +125 °C - qualified for engine bay and ADAS ECU environments |
Pinout & Package
XQFN12 package (SOT1174-1): 1.70 × 2.0 × 0.50 mm body, 12-terminal no-lead construction with side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA | Power supply A | Reference for A-side inputs (A1–A4); sets input logic thresholds and drive strength |
| VCCB | Power supply B | Reference for B-side outputs (YB1–YB4); defines output voltage swing and load drive capability |
| A1–A4 | Data inputs | Schmitt-triggered, with 6.5 MΩ internal pull-down - eliminates floating states and tolerates slow/noisy edges |
| YB1–YB4 | Data outputs | 3-state, actively driven push-pull outputs referenced to VCCB; support bidirectional bus sharing when enabled |
| OE | Output enable | Active-HIGH control referenced to VCCA or VCCB domain; float-safe for default Hi-Z at power-up/power-down |
| GND | Ground | Common reference for both supplies; thermal pad (non-electrical) must remain floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including lifetime reliability testing |
| Dual-supply IOFF protection | Prevents backflow current when either VCCA or VCCB is powered down or disconnected - eliminates need for external blocking diodes |
| Schmitt-trigger inputs with pull-down | 6.5 MΩ internal resistor ensures defined logic state even with open inputs; hysteresis rejects >10% noise margin |
| Suspend mode on supply loss | Automatic Hi-Z transition when VCCA or VCCB <100 mV or floating - isolates buses without software intervention |
| XQFN12 with side-wettable flanks | Enables automated optical inspection of solder joints - improves manufacturing yield and field-reliability traceability |
Applications
| Automotive Body Control Module (BCM) | ADAS Camera Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXU0204BQ-Q100 | DHVQFN14 package (2.5 × 3 × 0.85 mm); identical electrical specs and AEC-Q100 Grade 1 rating | Larger footprint; better thermal dissipation (Ptot = 500 mW vs. 250 mW) but no side-wettable flanks | Select when board space allows larger package and higher power margin is needed for sustained 250 Mbps operation |
| NXU0304PW-Q100 | TSSOP14 package (4.4 mm body width); same function and qualification, but no AOI-supporting side-wettable flanks | Through-hole compatible footprint; lower density than XQFN12; not suitable for ultra-compact automotive modules | Choose for legacy assembly lines lacking XQFN reflow capability or where manual inspection replaces AOI |
Compared with NXU0204BQ-Q100 and NXU0304PW-Q100, the NXU0104GU12-Q100 delivers identical translation performance in the smallest footprint with AOI-ready solder joints-critical for high-reliability automotive modules where miniaturization and process traceability are mandatory.

FAQ
Can the OE pin be left unconnected during power-up?
Yes. The OE pin is designed to be float-safe: when left unconnected or externally pulled to ground, it defaults to LOW, placing all YBn outputs in high-impedance state. This ensures bus isolation during power sequencing mismatches common in automotive ECUs, eliminating risk of contention or latch-up before firmware initialization.
What happens if VCCA is powered but VCCB is disconnected?
The device enters suspend mode: all YBn outputs transition to high-impedance state within nanoseconds, and IOFF circuitry blocks backflow current from VCCA into the floating VCCB rail. This behavior is guaranteed per datasheet Section 8.4 and prevents damage to downstream 3.3 V or 5.0 V receivers during partial system power loss.
Does the Schmitt-trigger input require external pull-up resistors?
No. Each An input includes a 6.5 MΩ internal pull-down resistor, ensuring a defined LOW state when un-driven. If an external pull-up is needed (e.g., for wired-OR logic), it must be ≤1 MΩ to avoid contention; otherwise, the internal pull-down alone suffices for noise-immune operation in most automotive signal routing scenarios.
How does the XQFN12 package support automated optical inspection?
The SOT1174-1 package features side-wettable flanks - exposed copper on the vertical package edges - allowing AOI systems to inspect solder fillet formation and wetting quality. This provides 100% traceable solder joint verification critical for zero-defect automotive manufacturing, unlike standard QFN packages that hide solder joints beneath the body.
