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 sink more than the test conditions (20mA at V
4. Although each I/O port can source more than the test conditions (20mA at V
conditions (non-transient), the following must be observed:
ATmega48:
1] The sum of all IOL, for ports C0 - C5, should not exceed 70 mA.
2] The sum of all IOL, for ports C6, D0 - D4, should not exceed 70 mA.
3] The sum of all IOL, for ports B0 - B7, D5 - D7, should not exceed 70 mA.
ATmega88/168:
1] The sum of all IOL, for ports C0 - C5, should not exceed 100 mA.
2] The sum of all IOL, for ports C6, D0 - D4, should not exceed 100 mA.
3] The sum of all IOL, for ports B0 - B7, D5 - D7, 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.
