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 Vcc = 3V) under steady state
4. Although each I/O port can source more than the test conditions (20mA at Vcc = 5V, 10mA at Vcc = 3V) under steady state
conditions (non-transient), the following must be observed:
PDIP Package:
1] The sum of all IOL, for all ports, should not exceed 200mA.
2] The sum of all IOL, for port A0 - A7, should not exceed 100mA.
3] The sum of all IOL, for ports B0 - B7,C0 - C7, D0 - D7 and XTAL2, should not exceed 100mA.
TQFP and QFN/MLF Package:
1] The sum of all IOL, for all ports, should not exceed 400mA.
2] The sum of all IOL, for ports A0 - A7, should not exceed 100mA.
3] The sum of all IOL, for ports B0 - B4, should not exceed 100mA.
4] The sum of all IOL, for ports B3 - B7, XTAL2, D0 - D2, should not exceed 100mA.
5] The sum of all IOL, for ports D3 - D7, should not exceed 100mA.
6] The sum of all IOL, for ports C0 - C7, 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.
conditions (non-transient), the following must be observed:
PDIP Package:
1] The sum of all IOH, for all ports, should not exceed 200mA.
2] The sum of all IOH, for port A0 - A7, should not exceed 100mA.
3] The sum of all IOH, for ports B0 - B7,C0 - C7, D0 - D7 and XTAL2, should not exceed 100mA.
TQFP and QFN/MLF Package:
1] The sum of all IOH, for all ports, should not exceed 400mA.
2] The sum of all IOH, for ports A0 - A7, should not exceed 100mA.
3] The sum of all IOH, for ports B0 - B4, should not exceed 100mA.
4] The sum of all IOH, for ports B3 - B7, XTAL2, D0 - D2, should not exceed 100mA.
