1. “Max” means the highest value where the pin is ensured to be read as low.
2. “Min” means the lowest value where the pin is ensured 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 conditions (non-transient), the following must be observed: PDIP, TQFP, and QFN/MLF Package: 1] The sum of all IOL, for all ports, should not exceed 300 mA. 2] The sum of all IOL, for ports C0 - C5 should not exceed 100 mA. 3] The sum of all IOL, for ports B0 - B7, C6, D0 - D7 and XTAL2, should not exceed 200 mA. If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not ensured to sink current greater than the listed test condition.
4. Although each I/O port can source more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed: PDIP, TQFP, and QFN/MLF Package: 1] The sum of all IOH, for all ports, should not exceed 300 mA. 2] The sum of all IOH, for port C0 - C5, should not exceed 100 mA. 3] The sum of all IOH, for ports B0 - B7, C6, D0 - D7 and XTAL2, should not exceed 200 mA. If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not ensured to source current greater than the listed test condition.
5. Minimum VCC for Power-down is 2.5V.
