NXU0202DC-Q100H

Translators, Level Shifters Overview

The NXU0202DC-Q100H is a Nexperia automotive-grade, 2-bit dual-supply level translating buffer with Schmitt-trigger inputs and 3-state outputs. It facilitates asynchronous communication between data buses by translating voltages between any nodes within the 0.9 V to 5.5 V range for both VCCA and VCCB supplies. The device supports unidirectional transmission from the A bus to the B bus on three channels and from the B bus to the A bus on one channel. It features low static power consumption of 3 µA at 25 °C and high output drive capability of 12 mA at 5 V. Packaged in an 8-lead VSSOP (SOT765-1) plastic very thin shrink small outline package, it operates reliably from -40 °C to +125 °C.

Translators, Level Shifters FAQ

How does the device handle power supply sequencing?

No power supply sequencing is required. Output glitches during power supply transitions are prevented, ensuring no glitches appear on the outputs during power-up/down.

What happens if one of the power supplies is disconnected?

If either VCCA or VCCB is disconnected (floating) or drops below 100 mV, the device enters suspend mode (Hi-Z), disabling all outputs and engaging IOFF circuitry to prevent backflow current.
