PI4ULS3V504AZMAEX

Translators, Level Shifters Overview

The PI4ULS3V504AZMAEX is a 4-bit configurable dual-supply autosensing bidirectional level translator designed for push-pull applications. It operates with VCCA ranging from 0.85V to 2.7V and VCCB from 1.35V to 3.6V, allowing independent supply configurations where VCCA may be greater than, equal to, or less than VCCB. The device supports a maximum data rate of 280 Mb/s at 15 pF load and guarantees 30 pF capacitive drive capability. It features low bit-to-bit skew, overvoltage tolerant I/O pins, non-preferential power-up sequencing, and power-off protection.
