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 (10mA at VCC = 5V, 6mA at VCC = 3V) under steady state
conditions (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.
4. Although each I/O port can source more than the test conditions (10mA at VCC = 5V, 8mA at VCC = 3V) under steady
state 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.
5. Minimum VCC for power-down is 2.5V.
6. The analog comparator Propogation Delay equals 1 comparator clock plus 30nS. See Section 20. “Analog Compara-
tor” on page 225 for comparator clock definition.
