C - 06 March, 2001 TS80C51RA2/RD2 TS83C51RB2/RC2/RD2 TS87C51RB2/RC2/RD2 For timing purposes a port pin is no longer floating when a 100 mV change from load voltage occurs and begins to float when a 100 mV change from the loaded VOH/VOL level occurs. IOL/IOH ≥± 20mA. 10.5.15. Clock Waveforms Valid in normal clock mode. In X2 mode XTAL2 signal must be changed to XTAL2 divided by two. Figure 33. Clock Waveforms 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 (TA=25°C fully loaded) RD and WR propagation delays are approximately 50ns. The other signals are typically 85 ns. Propagation delays are incorporated in the AC specifications.
