Hi team,
What does the VT range mean? Is it a range of chip by chip variation? If users operates without intermidiate state, user must send >3.15V as high and <0.9V as low?

Best regards,
Hayashi

Yes, these are caused by manufacturing and temperature variations, and you must use the worst-case values. See Understanding Schmitt Triggers.
