Note:
  1. “Max.” means the highest value where the pin is guaranteed to be read as low.
  2. “Min.” means the lowest value where the pin is guaranteed to be read as high.
  3. Although each I/O port can source more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed:

    1. The sum of all IOH, for ports C0 - C5, D0- D4, ADC7, RESET should not exceed 100 mA.

    2. The sum of all IOH, for ports B0 - B5, D5 - D7, ADC6, XTAL1, XTAL2 should not exceed 100 mA.


      If IIOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition.

  4. Although each I/O port can sink more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed:

    1. The sum of all IOL, for ports C0 - C5, ADC7, ADC6 should not exceed 100 mA.
    2. The sum of all IOL, for ports B0 - B5, D5 - D7, XTAL1, XTAL2 should not exceed 100 mA.

    3. The sum of all IOL, for ports D0 - D4, RESET should not exceed 100 mA.


      If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition.
