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 sink more than the test conditions (20mA at V
CC
= 5V, 10mA at V
CC
=
3V) under steady state conditions (non-transient), the following must be observed:
PDIP Package:
3.1. The sum of all IOL, for all ports, should not exceed 200mA.
3.2. The sum of all IOL, for ports A0 - A7 should not exceed 100mA.
