NXU0204PW-Q100J

Translators, Level Shifters Overview

The NXU0204PW-Q100J 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 outputs (YB1, YB2, YA3, YA4). Both VCCA and VCCB operate between 0.9 V and 5.5 V. Data transmits 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 between 1.8 V and 5 V.

Translators, Level Shifters Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Schmitt-trigger inputs with integrated static high ohmic pull-down resistors
• IOFF circuitry provides partial power-down mode operation preventing backflow current
• Suspend mode activates when either supply voltage drops below 100 mV or disconnects

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the component matches the specific TSSOP-14 package configuration designated by the PW suffix. Confirm that the Q100 designation indicates compliance with Automotive Electronics Council Grade 1 requirements. Ensure the ordering code includes the correct temperature range extension for -40 °C to +125 °C operation. Cross-reference the marking code NXU0204 against the physical device to validate authenticity.

Translators, Level Shifters Selection Notes

Select this component when asymmetric bidirectional translation is required, specifically needing three channels flowing from domain A to B and one channel from B to A. Choose this part over symmetric alternatives like the NXU0104 if the application demands mixed-direction data flow within a single package. Verify that the output enable pin can be referenced to the appropriate domain using the VCC(MIN) circuitry.

Translators, Level Shifters Part Context

This device belongs to the Nexperia NXU0x04 family of 4-bit dual-supply voltage level translators. It shares functional similarities with the NXU0104-Q100 and NXU0304-Q100 but differs in channel directionality. The PW suffix identifies the plastic thin shrink small outline package with 14 leads and a body width of 4.4 mm.

Translators, Level Shifters FAQ

How does the NXU0204 handle power supply sequencing?

No power supply sequencing is required. The IOFF circuitry prevents damaging backflow currents if one supply is disconnected or floating, and output glitches during transitions are prevented.

What is the function of the OE pin?

The Output Enable (OE) pin allows connection to either the VCCA or VCCB domain. When set LOW, it disables the outputs and enters a high-impedance OFF-state to isolate the buses.
