NXU0104BZZ

Translators, Level Shifters Overview

The NXU0104BZZ is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs. It features four data inputs (A1-A4) and four data outputs (YB1-YB4). Both VCCA and VCCB operate between 0.9 V and 5.5 V, supporting translation between nodes like 1.2 V, 1.8 V, 3.3 V, and 5.0 V. Data transfers unidirectionally from A to B at up to 250 Mbps. The device includes an output enable pin (OE), IOFF circuitry for partial power-down protection, and operates from -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Schmitt-trigger inputs with integrated static high ohmic pull-down resistors
• IOFF circuitry prevents backflow current during power-down or floating supply conditions
• Suspend mode activates when either supply voltage drops below 100 mV or disconnects
• Low noise overshoot and undershoot maintained below 10% of VCCO

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the package type DHXQFN-14 (SOT8014-1) matches your PCB footprint requirements. Confirm that the operating temperature range of -40 °C to +125 °C meets your environmental specifications. Ensure supply voltages remain within the 0.9 V to 5.5 V limits for both VCCA and VCCB domains to maintain proper functionality.

Translators, Level Shifters Selection Notes

Select this component for applications requiring asynchronous communication between buses with different voltage levels. The fixed unidirectional transfer direction from A to B suits simple interface buffering. Consider the DHXQFN-14 package if space constraints require a compact, leadless thermal enhanced design with a 0.4 mm pitch.

Translators, Level Shifters Part Context

This part belongs to the Nexperia NXU0x04 family of 4-bit dual-supply level translating buffers. Similar functional variants include the NXU0204 and NXU0304. The NXU0104BZZ specifically utilizes the DHXQFN-14 package, distinguishing it from other package options like TSSOP-14 or DHVQFN-14 within the same logical family.

Translators, Level Shifters FAQ

How does the OE pin behave during power-up?

The OE pin can be left floating or externally pulled down to ground to ensure the outputs remain in a high-impedance state during power-up or power-down transitions.

What happens if one supply voltage is disconnected?

If either VCCA or VCCB becomes disconnected (floating) or drops below 100 mV, the device enters suspend mode, disabling all outputs and entering a high-impedance OFF-state.
