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.

otherwise noted.

Core and external rail.

[3]

3.3 V pad.

[4]

On ADC related pins.

[5]

Including voltage on outputs in 3-state mode.

[6]

[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.
