Note 4: Pins G6 and RESET are designed with a high voltage input network for factory testing. 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 750X (typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 5: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
