Nexperia USA Inc. NEVB-NXU0104UL

Overview

NEVB-NXU0104UL from Nexperia is a two-layer evaluation board designed for the NXU0104 4-bit dual-supply voltage level shifter in DHXQFN14 (SOT8014-1) package. It implements Schmitt-trigger inputs with 6.5 MΩ pull-downs, OE control selectable between VCCA and VCCB, and supports 0.9 V to 5.5 V operation on both rails. The board enables validation of high-speed level translation up to 250 Mbps in mixed-voltage I²C, GPIO, and UART interconnect applications.

For engineers reviewing the NEVB-NXU0104UL datasheet, NEVB-NXU0104UL pinout, NEVB-NXU0104UL application, or NEVB-NXU0104UL equivalent, this board provides verified signal integrity testing, configurable loading for rise/fall time analysis, OE domain selection flexibility, and direct access to all A/B-side I/O pins via 8-position headers - critical for prototyping low-power, multi-rail embedded interfaces.

Technical Context

The NEVB-NXU0104UL replicates real-world system integration of the NXU0104 device by embedding series 0 Ω resistors and parallel load footprints (C1–C8) on each I/O line. It includes dedicated jumpers for OE biasing to either VCCA or VCCB, enabling domain-aware enable control under asymmetric supply conditions.

Each input features an integrated Schmitt trigger and 6.5 MΩ pull-down resistor, ensuring noise immunity and defined logic state during floating conditions. The board supports suspend mode when either supply drops below 100 mV, matching the IC's native power-loss behavior without external circuitry.

FAQ

What voltage ranges can be tested using the NEVB-NXU0104UL?

The board supports independent VCCA and VCCB supplies from 0.9 V to 5.5 V each, allowing full characterization of level translation across ultra-low-voltage logic (e.g., 0.9 V IO), standard 1.8 V/3.3 V domains, and legacy 5 V peripherals without hardware modification.

How is output enable (OE) configured on this evaluation board?

OE is controlled via a 3-pin header (J5): the center pin connects to the NXU0104 OE input, while outer pins route through 10 kΩ resistors to VCCA or VCCB. A jumper selects the pull-up rail, and an internal OE pull-down ensures safe default state when unconnected.

Can the NEVB-NXU0104UL be used to evaluate timing parameters like propagation delay?

Yes - each I/O line includes a populated 0 Ω series resistor and an unpopulated capacitor footprint (C1–C8) to ground. By adding capacitive loads, users can directly measure rise/fall time degradation and propagation delay variation under realistic loading conditions.

Does the board support both DHXQFN14 and TSSOP14 packages of the NXU0104?

The board is assembled with the DHXQFN14 (SOT8014-1) variant of NXU0104, but includes a secondary footprint compatible with TSSOP14 (SOT402-1). Users may desolder the DHXQFN14 device and mount the TSSOP14 version using standard rework techniques.
