NXU0104GU12X

Translators, Level Shifters Overview

The NXU0104GU12X is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs. It features four data inputs (An) and four data outputs (YBn). Both VCCA and VCCB operate between 0.9 V and 5.5 V, supporting translation between nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device facilitates asynchronous unidirectional communication from the A bus to the B bus. It includes IOFF circuitry for partial power-down applications and prevents backflow current during power transitions.

Translators, Level Shifters Feature Summary

• Dual-supply operation allows flexible voltage translation across multiple standard logic levels without requiring specific supply sequencing.
• Integrated Schmitt-trigger inputs provide noise immunity and tolerance for slow input signals in noisy environments.
• IOFF protection circuitry ensures safe partial power-down mode by preventing damaging backflow currents when supplies are disconnected or powered down.

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the package type matches the required PCB footprint, specifically the XQFN12 (SOT1174-1) variant for this suffix. Confirm that the operating temperature range of -40 °C to +125 °C aligns with system requirements. Ensure design accounts for the OE pin configuration to manage high-impedance states correctly during power cycles.

Translators, Level Shifters Selection Notes

Select this component when interfacing buses with different voltage domains requiring robust noise filtering. The Schmitt-trigger feature is critical for applications with slow rise/fall times. Consider the 3-state output capability if bus isolation is necessary via the OE pin. Verify that the maximum data rate requirements fit within the specified limits for the target voltage translation direction.

Translators, Level Shifters Part Context

This part belongs to the NXU0104 family of level translators manufactured by Nexperia. It is functionally similar to the NXU0204 and NXU0304 models but offers a 4-bit configuration. The GU12 suffix specifically denotes the XQFN12 package, distinguishing it from TSSOP or other QFN variants in the same logical family.

Translators, Level Shifters FAQ

How does the device handle power-down scenarios?

The NXU0104GU12X utilizes IOFF circuitry to prevent potentially damaging backflow current through the device when it is powered down or if one of the power supplies is disconnected.

What is the function of the OE pin?

The Output Enable (OE) pin controls the 3-state outputs. When set LOW, the outputs enter a high-impedance OFF-state, isolating the buses. It can be referenced to either the VCCA or VCCB domain.
