NOTES
1 ‘‘Typicals’’ are based on a limited number of samples taken from early manufacturing lots and are not guaranteed The
values listed are at room temp 5V
2 Capacitive loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the VOLs of ALE and Ports
1 and 3 The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins make 1-
to-0 transitions during bus operations In the worst cases (capacitive loading l 100pF) the noise pulse on the ALE pin may
exceed 0 8V In such cases it may be desirable to qualify ALE with a Schmitt Trigger or use an address latch with a Schmitt
Trigger STROBE input
3 Capacitive loading on Ports 0 and 2 may cause the VOH on ALE and PSEN to momentarily fall below the 0 9 VCC
specification when the address bits are stabilizing
