7. Limiting values
[1] The following applies to the Limiting values:
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 operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless
otherwise noted.
[2] Core and external rail.
[3] 3.3 V pad.
[4] On ADC related pins.
[5] Including voltage on outputs in 3-state mode.
[6] Only valid when the V
DD
supply voltage is present.
[7] Not to exceed 4.6 V.
[8] Per supply pin.
[9] The peak current is limited to 25 times the corresponding maximum current.
[10] Per ground pin.
[11] Dependent on package type.
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
