Product details
Overview
NXU0204BQ-Q100 from Nexperia is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs, 3-state outputs, AEC-Q100 Grade 1 automotive qualification, 0.9 V to 5.5 V dual supply range (VCCA/VCCB), and 250 Mbps max data rate for ≥1.8 V to 5 V translation. It enables unidirectional bus translation-A→B on three channels, B→A on one channel-in automotive infotainment and ADAS domain controllers interfacing mixed-voltage peripherals.
For engineers reviewing the NXU0204BQ-Q100 datasheet, NXU0204BQ-Q100 pinout, NXU0204BQ-Q100 application, or NXU0204BQ-Q100 equivalent, key selection considerations include dual-rail IOFF protection, suspend-mode behavior during partial power-down, Schmitt-trigger noise immunity for slow/noisy signals, and OE pin compatibility with either VCCA or VCCB domains.
Technical Context
This device implements asynchronous bidirectional level translation using independent VCCA and VCCB supplies, with fixed-direction signal paths: A1/A2/YA3/YA4 form an A-side interface referenced to VCCA, while YB1/YB2/B3/B4 form a B-side interface referenced to VCCB. The OE input controls all four outputs simultaneously and supports floating or ground-biased assertion for power-up safety.
Its Schmitt-trigger inputs feature integrated 6.5 MΩ pull-down resistors and hysteresis (e.g., 0.96 V typical at 5.5 V), enabling robust operation with slow edges or noisy waveforms. The IOFF circuitry ensures <2 µA off-state leakage when either supply drops below 100 mV or floats, eliminating backflow current without supply sequencing requirements.
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, and 5.0 V domains |
| Max Data Rate | 250 Mbps (≥1.8 V to 5 V translation) - supports high-speed UART, SPI, and JTAG in automotive ECUs |
| IOFF Leakage | <2 µA when either VCCA or VCCB <100 mV or floating - prevents damaging backflow during partial power-down |
| Input Hysteresis | 0.96 V typical at VCC = 5.5 V - rejects noise up to ±480 mV on slow-rising/falling signals |
| Output Drive | 12 mA sink/source at 4.5 V - drives standard CMOS loads with fast edge rates and low overshoot (<10% VCCO) |
| ESD Rating | HBM ±2500 V, CDM ±1500 V - meets automotive system-level ESD robustness requirements |
| Operating Temp | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications |
Pinout & Package
DHVQFN14 package (SOT762-1), 2.5 × 3 × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA | Supply for A-side I/O | Power domain for inputs A1/A2 and outputs YA3/YA4; sets input reference and output high-level voltage |
| VCCB | Supply for B-side I/O | Power domain for inputs B3/B4 and outputs YB1/YB2; defines B-side logic thresholds and drive strength |
| A1, A2 | A-side data inputs | Schmitt-triggered inputs referenced to VCCA; translate from A-bus to B-bus (YB1/YB2) |
| B3, B4 | B-side data inputs | Schmitt-triggered inputs referenced to VCCB; translate from B-bus to A-bus (YA3/YA4) |
| YB1, YB2 | B-side data outputs | 3-state outputs driven by A1/A2; active HIGH, disabled when OE = LOW |
| YA3, YA4 | A-side data outputs | 3-state outputs driven by B3/B4; active HIGH, disabled when OE = LOW |
| OE | Output enable | Active-HIGH control referenced to VCCA or VCCB via internal VCC(MIN); floating-safe for power-up isolation |
| GND | Ground reference | Common 0 V reference for both supply domains and signal integrity; thermal pad must remain floating or tied to GND |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent VCCA/VCCB rails (0.9–5.5 V each) enable flexible inter-domain communication without level-shifter ICs |
| Schmitt-trigger inputs | Integrated 6.5 MΩ pull-down + hysteresis (0.96 V typ at 5.5 V) suppresses noise on slow-rising signals in noisy automotive environments |
| IOFF partial power-down | Prevents backflow current when either supply is disconnected or <100 mV - eliminates need for external isolation switches |
| OE domain flexibility | OE pin accepts logic levels referenced to VCCA or VCCB - simplifies control routing in mixed-voltage PCB layouts |
| Automotive qualification | AEC-Q100 Grade 1 (-40 °C to +125 °C), JEDEC-compliant standards (JESD8-12 through JESD12-6), and latch-up immunity >100 mA |
Applications
| Automotive Infotainment Head Unit | ADAS Camera Interface Module |
|---|---|
Use Scenario: Interfacing 1.8 V MIPI CSI-2 camera sensor to 3.3 V SoC image processor across separate power domains. IC Role / Device Role / Timing Role: Unidirectional level translation from B-side (sensor) to A-side (SoC) on YA3/YA4, with OE synchronized to sensor frame sync. Use Value: Eliminates discrete resistor-based translators; Schmitt inputs tolerate sensor clock jitter and trace-induced ringing. |
Use Scenario: Connecting 5.0 V radar MCU GPIOs to 1.2 V FPGA configuration pins during boot sequence. IC Role / Device Role / Timing Role: A→B translation (A1/A2 → YB1/YB2) with OE asserted only after both VCCA and VCCB stabilize. Use Value: IOFF protection prevents FPGA damage during staggered MCU/FPGA power-up; suspend mode ensures Hi-Z before full rail establishment. |
| Body Control Module (BCM) | Electric Power Steering (EPS) ECU |
Use Scenario: Isolating 2.5 V LIN transceiver logic from 5.0 V microcontroller I/O during sleep/wake transitions. IC Role / Device Role / Timing Role: Bidirectional translation with OE controlled by MCU wake signal; 3-state isolates buses during deep sleep. Use Value: Low 3 µA static current at 25 °C extends battery life; suspend mode activates automatically if VCCB drops during LIN bus fault. |
Use Scenario: Level-shifting 1.5 V torque sensor SPI interface to 3.3 V motor controller ASIC. IC Role / Device Role / Timing Role: Fixed-direction A→B translation (A1/A2 → YB1/YB2) with Schmitt inputs rejecting EMI from nearby motor drivers. Use Value: 250 Mbps capability exceeds SPI clock requirements; <10% VCCO overshoot ensures signal integrity near high-noise power stages. |
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 |
|---|---|---|---|
| NXU0104-Q100 | 2-bit version, identical VCCA/VCCB range and Schmitt inputs but half the channel count | Lower pin count and smaller footprint; insufficient for 4-signal interfaces like quad-SPI or multi-channel UART | Select when only two bidirectional lines require translation and board space is constrained |
| NXU0304-Q100 | Includes auto-direction sensing (no OE pin); different pinout and timing behavior (enable latency not applicable) | Eliminates OE control logic but lacks deterministic direction control - unsuitable for protocols requiring fixed A→B/B→A paths | Prefer for I²C or SMBus where direction is data-dependent; avoid for UART/SPI/JTAG with explicit direction signals |
Compared with NXU0104-Q100 and NXU0304-Q100, the NXU0204BQ-Q100 provides deterministic 4-channel unidirectional translation with OE control, making it optimal for protocol-constrained automotive interfaces where direction stability and channel density are critical.

FAQ
Can the OE pin be left unconnected during power-up?
Yes. The OE pin supports floating operation due to internal VCC(MIN) circuitry that references OE to the lower of VCCA or VCCB. When left floating or pulled to ground, OE defaults to LOW, placing all outputs in high-impedance state - ensuring safe isolation during power sequencing without external biasing.
What happens if only VCCA is powered while VCCB is disconnected?
The device enters suspend mode: all outputs transition to high-impedance OFF-state, and IOFF circuitry limits leakage to <2 µA. This prevents backflow current from VCCA into the floating VCCB rail, protecting downstream B-side circuitry without requiring external power-good monitoring.
Does the Schmitt-trigger input eliminate the need for external RC filtering?
Yes - the integrated 6.5 MΩ pull-down and hysteresis (e.g., 0.96 V at 5.5 V) provide inherent noise rejection for slow edges and EMI. External RC filters are unnecessary for typical automotive noise profiles; however, if input rise/fall times exceed 100 ns, dynamic current may increase, so layout best practices still apply.
How does the DHVQFN14 package support automated optical inspection (AOI)?
The SOT762-1 package features side-wettable flanks - vertical copper surfaces along the perimeter - enabling AOI systems to inspect solder joint quality from the side rather than relying solely on top-down imaging. This improves defect detection for fine-pitch QFN assemblies in high-reliability automotive manufacturing.
