Hei to everyone,
I have a strange problem with the ALE signal. Address Latch Enable signal is used to latch the low byte of the address during access of external memory. In my case the ALE signal is directly connected to the Latch Enable input of SN74HCT573. My problem that the Address latch is only working well when an oscilloscoop is connected on the ALE pin. What's the reason for this behaviour? A small condensator, 82pf, over ALE solved the problem. Is this a good solution. Thank you in advance, for help
