This diagram indicates when signals are clocked internally. The time it takes the signals
to propagate to the pins, however, ranges from 25 to 125 ns. This propagation delay is
dependent on variables such as temperature and pin loading. Propagation also varies
from output to output and component. Typically though (T
WR propagation delays are approximately 50 ns. The other signals are typically 85 ns.
Propagation delays are incorporated in the AC specifications.
