Limiting values
[1]
The following applies to Table 10:
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.
[2]
Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k
Ω series resistor.
