NXU0104BQX

Translators, Level Shifters Overview

The NXU0104BQX 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 like 1.2 V, 1.8 V, 3.3 V, and 5.0 V. Data transmits unidirectionally from A to B bus. The OE pin isolates buses when LOW. IOFF circuitry prevents backflow current during power-down.

Translators, Level Shifters Feature Summary

• Dual-supply operation allows flexible voltage translation across multiple standard logic levels
• Schmitt-trigger inputs provide noise immunity for slow or noisy signals
• IOFF protection prevents damaging backflow currents in partial power-down states
• Suspend mode automatically disables outputs if supply voltages drop below thresholds

Translators, Level Shifters Applications

• General purpose I/O level translation
• UART, SPI, and JTAG protocol support
• Consumer electronics interfaces

Translators, Level Shifters FAQ

How does the device handle power supply sequencing?

No power supply sequencing is required. The device prevents output glitches during power supply transitions and enters suspend mode if either supply drops below 100 mV or becomes floating.

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 VCCA or VCCB domain.
