NXU0204PWJ

Translators, Level Shifters Overview

The NXU0204PWJ 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) and four data outputs (YB1, YB2, YA3, YA4). Both VCCA and VCCB operate between 0.9 V and 5.5 V. Data translates unidirectionally from the A bus to the B bus on three channels and from the B bus to the A bus on one channel. The maximum data rate reaches 250 Mbps for translations of 1.8 V to 5 V. It includes an output enable input (OE) and IOFF circuitry for partial power-down applications.

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 specific package type matches the design requirements, as the NXU0204 family includes TSSOP-14, DHVQFN-14, DHXQFN-14, and XQFN-12 options. Confirm that the ordering suffix 'PWJ' corresponds to the TSSOP-14 variant. Ensure the selected component meets the required temperature range specifications for the intended operating environment before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when asynchronous communication requires fixed-direction translation across mixed voltage domains. It is suitable for systems needing low static power consumption and robust protection against backflow currents. Consider the available package options based on board space constraints and thermal dissipation needs. Verify compatibility with the target voltage nodes ranging from 0.9 V to 5.5 V.
