C511 / C513
Notes:
1)
Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the
V
OL
of ALE
and port 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 operation. In the worst case (capacitive loading > 100 pF), the noise
pulse on ALE line may exceed 0.8 V. 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.
2)
Capacitive loading on ports 0 and 2 may cause the
V
OH
on ALE and PSEN to momentarily fall bellow the
0.9
V
CC
specification when the address lines are stabilizing.
