Absolute Maximum Ratings
[6]
This device contains circuitry to protect the input against
damage due to high static voltages or electric fields; however,
precautions should be taken to avoid application of any
voltage higher than the absolute maximum rated voltages to
this circuit. For proper operation, V
IN
and V
OUT
should be
constrained to the range, V
SS
< (V
IN
or V
OUT
) < V
DD
. All digital
inputs are tied high or low internally. Refers to electrical speci-
fications for operating supply range.
