2. Capacitive loading on Ports 0 & 2 may cause spurious noise to be superimposed on the V
OL
s of ALE and Ports 1 & 3. The noise due
to external bus capacitance discharging into the Port 0 & 2 pins when the pins make 1-to-0 transitions during bus operations. In the
worst cases (capacitive loading > 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. Load capacitance for Port 0, ALE & PSEN#= 100pF, load capacitance for all other outputs = 80pF.
4. Capacitive loading on Ports 0 & 2 may cause the V
OH
on ALE and PSEN# to momentarily fall below the V
DD
- 0.7 specification when
the address bits are stabilizing.
5. Pins of Ports 1, 2 & 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its
maximum value when V
IN
is approximately 2V.
6. Pin capacitance is characterized but not tested. EA# is 25pF (max).
