Notes:
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 VCC = 5V, 10mA at V
CC = 3V) under steady state
conditions (non-transient), the following must be observed:
1.)The sum of all IOL, for ports PB0-PB7, XTAL2, PD0-PD7 should not exceed 100mA.
2.)The sum of all I
OH, for ports PA0-PA3, PC0-PC7 should not exceed 100mA.
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.
4. Although each I/O port can source more than the test conditions (20mA at VCC = 5V, 10mA at V
CC = 3V) under steady state
conditions (non-transient), the following must be observed:
1.)The sum of all IOL, for ports PB0-PB7, XTAL2, PD0-PD7 should not exceed 100mA.
2.)The sum of all I
OH, for ports PA0-PA3, PC0-PC7 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.
