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. Propa-
gation also varies from output to output and component. Typically though (T
delays are approximately 50 ns. The other signals are typically 85 ns. Propagation delays are incorporated in the AC
specifications.
