NXU0104BQ-Q100X

Translators, Level Shifters Overview

The NXU0104BQ-Q100X is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs. It facilitates asynchronous communication between data buses, supporting unidirectional transmission from the A bus to the B bus across four channels. Both VCCA and VCCB supply voltages operate within a range of 0.9 V to 5.5 V, enabling translation between standard nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device achieves maximum data rates up to 250 Mbps for translations between 1.8 V and 5 V.

Translators, Level Shifters FAQ

How does the device handle power supply transitions?

No power supply sequencing is required. The device prevents output glitches during power supply transitions, ensuring that glitches do not appear on the output during power-up or power-down phases.

What happens if one of the supply voltages disconnects?

If either VCCA or VCCB drops below 100 mV or becomes disconnected (floating), the product enters suspend mode. All outputs are disabled and enter a high-impedance OFF-state to isolate the buses.
