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 (20 mA at V

sient), the following must be observed:

1] The sum of all IOL, for all ports, should not exceed 400 mA.

2] The sum of all IOL, for ports C0 - C5, should not exceed 200 mA.

3] The sum of all IOL, for ports C6, D0 - D4, should not exceed 300 mA.

4] The sum of all IOL, for ports B0 - B7, D5 - D7, should not exceed 300 mA.

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. For temperature range +125°C to +150°C only. For –40°C to +125°C, refer to ATtiny167automotive datasheet.
