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 (20 mA at Vcc = 5V, 10 mA at Vcc = 3V) under steady state
4. Although each I/O port can source more than the test conditions (3 mA at Vcc = 5V, 1.5 mA at Vcc = 3V) under steady state
5. Minimum V
conditions (non-transient), the following must be observed:
1] The sum of all I
2] The sum of all I
3] The sum of all I
If IOL exceeds the test condition, V
than the listed test condition.
