Electrical Characteristics

1.1

Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this

specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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

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
