Note1: Under steady state (non-transient) conditions, IOL must be externally
Limited as follows: Maximum IOL per port pin : 10mA
Maximum IOL per 8-bit port : port 0 :26mA
port 1,2,3 :15mA
Maximum total IOL for all output pins : 71mA
If IOL exceeds the condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
Note2 : Minimum VCC for Power-down is 2V.
