what do you expect me to do when I can't find the 74VHC244? My search returned 30 results! Ashwin said:
All I asked was CAN i or CAN'T i use th 74HCT244E for 89s52. And all I said is: "Look at the schematic and TRY to find out why the 74VHC244 is needed!" Have a look at the datasheets of 74HC244 and 74VHC244 and try to find out where the difference is. Is this too much asked, if you are not willing to make a search here and read the links?? Have you had a look at the schematic I gave you? What is D1 needed for?? Kai |
