[1] The following applies to Table 9:
a) 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.
b) Parameters are valid over ambient temperature range unless otherwise specified. All voltages are with respect to VSS unless
otherwise noted.
