Note:
  1. VIL source < (GND – 0.3). Characterized but not tested.
  2. VIH source > (VDDIO + 0.3) for non-5V tolerant pins only.
  3. Digital 5V tolerant pins do not have an internal high side diode to VDDIO, and therefore, cannot tolerate any positive input injection current.
  4. Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted provided the absolute instantaneous sum of the input injection currents from all pins do not exceed the specified ∑IICT limit. To limit the injection current, the user must insert a resistor in series RSERIES (in other words, RS), between the input source voltage and device pin. The resistor value is calculated according to:
    • For negative Input voltages less than (GND – 0.3): RS ≥ absolute value of | ((VIL source – (GND – 0.3)) / IICL) |
    • For positive input voltages greater than (VDDIO + 0.3): RS ≥ ((VIH source – (VDDIO +0.3))/ IICH)
    • For Vpin voltages greater than VDDIO + 0.3 and less than GND – 0.3: RS = the larger of the values calculated above
  5. High load = 50 pF and Standard load = 30 pF.
