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 (10mA at V
4. Although each I/O port can source more than the test conditions (10mA at Vcc = 5V, 8mA at Vcc = 3V) under steady state

ditions (non-transient), the following must be observed:
1] The sum of all IOL, for ports B0 - B1, C2 - C3, D4, E1 - E2 should not exceed 70mA
2] The sum of all IOL, for ports B6 - B7, C0 - C1, D0 -D3, E0 should not exceed 70mA
3] The sum of all IOL, for ports B2 - B5, C4 - C7, D5 - D7 should not exceed 70mA
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
conditions (non-transient), the following must be observed:
1] The sum of all IOH, for ports B0 - B1, C2 - C3, D4, E1 - E2 should not exceed 100mA
2] The sum of all IOH, for ports B6 - B7, C0 - C1, D0 -D3, E0 should not exceed 100mA
3] The sum of all IOH, for ports B2 - B5, C4 - C7, D5 - D7 should not exceed 100mA
If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition
