Capacitive loads on Port 0 and Port 2 may degrade the LOW level output voltage of ALE, Port 1 and Port 3.
During a HIGH-to-LOW transition on the Port 0 and Port 2 pins and a capacitive load
>
100 pF, the ALE LOW level
may exceed 0.8 V. In the case that it is necessary to connect ALE to a Schmitt trigger input respectively use an
address latch with a Schmitt trigger STROBE input.
