NXU0204GU12X

Translators, Level Shifters Overview

The NXU0204GU12X is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs. It features four data inputs (A1, A2, B3, B4) and four outputs (YB1, YB2, YA3, YA4). Both VCCA and VCCB operate between 0.9 V and 5.5 V. Data translates unidirectionally from the A bus to the B bus on three channels, and from the B bus to the A bus on one channel. The device supports asynchronous communication with a maximum data rate of 250 Mbps for translations between 1.8 V and 5 V.

Translators, Level Shifters Feature Summary

• Schmitt-trigger inputs with integrated static high ohmic pull-down resistors ensure tolerance for slow and noisy input signals.
• IOFF circuitry prevents damaging backflow current during power-down or floating supply conditions, enabling partial power-down mode operation.
• Suspend mode activates when either supply voltage drops below 100 mV or disconnects, placing all outputs in a high-impedance state.
• Low noise overshoot and undershoot are maintained at less than 10% of VCCO across the operating range.

Translators, Level Shifters Applications

• General purpose I/O level translation
• Noisy environments or slow input signals
• Push-pull voltage translation for UART, SPI, and JTAG protocols

Translators, Level Shifters Procurement Notes

Verify the specific package designation GU12 corresponds to the XQFN-12 form factor before procurement. Confirm that the suffix 'X' aligns with the required reel or cut tape packaging configuration for your assembly line. Ensure the component meets the -40 °C to +125 °C temperature range requirements for your target application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing buses with different voltage domains, such as 1.8 V to 3.3 V or 3.3 V to 5.0 V. The fixed directionality requires careful pin mapping: three channels flow A-to-B, while one flows B-to-A. Use the OE pin to isolate buses during power transitions or when high-impedance states are necessary to prevent signal contention.

Translators, Level Shifters Part Context

This part belongs to the NXU0204 family of voltage level translators manufactured by Nexperia. It shares functional similarities with the NXU0104 and NXU0304 variants but offers specific channel configurations for mixed-direction translation. The GU12 package provides a compact footprint suitable for space-constrained consumer electronics and industrial control boards.

Translators, Level Shifters Replacement Considerations

NXU0104 and NXU0304 offer similar functions within the same product family. Verify channel directionality and pinout compatibility before substitution, as these variants may differ in bidirectional support or specific input/output assignments compared to the NXU0204.
