NXU0204BZZ

Translators, Level Shifters Overview

The NXU0204BZZ 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), four data outputs (YB1, YB2, YA3, YA4), and an output enable input (OE). Both VCCA and VCCB can be supplied at any voltage between 0.9 V and 5.5 V. The device facilitates asynchronous communication between data buses with fixed direction translation from the A bus to the B bus on three channels and from the B bus to the A bus on one channel.

Translators, Level Shifters Feature Summary

• Schmitt-trigger inputs with integrated static high ohmic pull-down resistor
• IOFF circuitry provides partial power-down mode operation
• Suspend mode when either supply voltage is below 100 mV or disconnected

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the package type DHXQFN-14 matches the design footprint requirements. Confirm that the operating temperature range of -40 °C to +125 °C aligns with the system environment. Ensure the OE pin configuration supports the required high-impedance state during power transitions.

Translators, Level Shifters Selection Notes

Select this component for applications requiring unidirectional translation across mixed voltage domains. The wide supply voltage range accommodates various logic levels. The integrated IOFF protection eliminates the need for external components in partial power-down scenarios.

Translators, Level Shifters Part Context

This part belongs to the Nexperia NXU0x04 series of 4-bit dual-supply voltage level translators. It shares functional similarities with the NXU0104 and NXU0304 variants within the same product family, designed for efficient bus isolation and signal translation.

Translators, Level Shifters FAQ

How does the device handle floating power supplies?

If either VCCA or VCCB drops below 100 mV or becomes disconnected (floating), the product enters suspend mode where all outputs are disabled and enter a high-impedance OFF-state.

What is the function of the OE pin?

The output enable (OE) input allows connection to the VCCA or VCCB domain. When set LOW, the outputs are disabled and enter a high-impedance OFF-state which isolates the buses.
