*2 Current dissipation values assume that V
in the no-load state, and all MOS input pull-ups are off.
Table 20-3 Allowable Output Current Sink Values
Conditions: V

Allowable output Low
current sink (per pin)
Allowable output Low
current sink (total)
Allowable output High
current sink (per pin)
Allowable output High
current sink (total)
Note: To avoid degrading the reliability of the chip, be careful not to exceed the output current sink
values in table 20-3. In particular, when driving a Darlington transistor pair or LED directly,
be sure to insert a current-limiting resistor in the output path. See figures 20-1 and 20-2.
