That covers office equipment, consumer electronics, and lab instruments. Not for an engine bay, rooftop telecom enclosure, or unheated warehouse. If the ambient around the board can dip below freezing, this part is out of its rated range.
The package body is 11.80 mm wide, matching the 28-TSOP I outline.
No. The supply voltage range is 4.5V to 5.5V. It will not operate on a 3.3V rail.
