1. 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
3. Although each I/O port can sink more than the test conditions (20mA at V
CC
= 5V) under steady state conditions (non-
transient), the following must be observed:
1] The sum of all IOL, for all ports, should not exceed 400mA.
2] The sum of all IOL, for ports C0 - C5, should not exceed 200mA.
3] The sum of all IOL, for ports C6, D0 - D4, should not exceed 300mA.
4] The sum of all IOL, for ports B0 - B7, D5 - D7, should not exceed 300mA.
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
