Limiting values
[1]
Stresses above those listed under
Table 7 “Limiting values”
may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in
Table 8 “DC electrical characteristics”
and
Table 9 “AC characteristics”
of this specification are not implied.
This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless otherwise
noted.
