Note 8:
Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages greater than V
CC
and the pins will have sink current
to V
CC
when biased at voltages greater than V
CC
(the pins do not have source current when biased at a voltage below V
CC
). The effective resistance to V
CC
is 750
(typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 9:
Condition and parameter valid only for part in HALT mode.
Note 10:
Parameter characterized but not tested.
