Figure 10. Clock Waveforms

Figure 39 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. Propagat

ion also varies from output to output and component. Typically though (T

A = 25°C fully loaded) RD and WR propagation

delays are approximat ely 50ns. The other signals are typically 85 ns. Propagation delays are incorporated in the AC

specifications.
