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.
Specifications subject to change without notice contact your sales representatives for the most recent information.
