Absolute Maximum Ratings:
(Note 1)
This device contains input protection
against damage due to high static
voltages or electric fields; however,
precautions should be taken to avoid
application of voltages higher than the
maximum rating.
Notes:
1. Exceeding these ratings may cause
permanent damage, functional
operation under these conditions is
not implied.
