NXU0304GU12-Q100X

Translators, Level Shifters Overview

The NXU0304GU12-Q100X is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs. It supports data rates up to 250 Mbps for translations between 1.8 V and 5 V. The device operates with supply voltages (VCCA and VCCB) ranging from 0.9 V to 5.5 V. It features low power consumption of 3 µA at 25 °C and includes IOFF circuitry for partial power-down protection. The component is automotive qualified to AEC-Q100 Grade 1 and housed in an XQFN-12 package.

Translators, Level Shifters Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Schmitt-trigger inputs with integrated static high ohmic pull-down resistors
• IOFF circuitry prevents damaging backflow current during power-down or floating supply conditions
• Output enable pin allows connection to either VCCA or VCCB domain

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the AEC-Q100 Grade 1 qualification aligns with the target automotive application requirements. Ensure the XQFN-12 footprint dimensions are compatible with the PCB layout constraints before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when asynchronous communication between buses requires bidirectional translation capabilities. The inclusion of three unidirectional channels and one bidirectional channel distinguishes it from similar models like the NXU0104. Verify that the required data rate does not exceed the specified maximum for the target voltage translation range.

Translators, Level Shifters Part Context

This part belongs to the NXU0x04 family of voltage level translating buffers manufactured by Nexperia. It shares functional similarities with the NXU0104 and NXU0204 but offers distinct channel configurations. The GU12 suffix indicates the XQFN-12 package variant, which is designed for space-constrained applications requiring robust solder joint inspection via side-wettable flanks.

Translators, Level Shifters FAQ

How does the device handle floating power supplies?

If either VCCA or VCCB drops below 100 mV or becomes disconnected, the device enters suspend mode, disabling all outputs to a high-impedance state.

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.
