Hi all,
I am working on a industrial project[ welding controller ] based on AT 89C55WD, i need clarification on follwing points.......
1] While selecting IC's for industrial projects which family[TTL,CMOS,LS,ALS,HC,HCT ....etc.] should we consider. I am working with 20MHz crystal oscillator. I need low power consumption IC's.
For testing purpose i used IC'S from local market, with which my project is almost on the way of complition. I am using AT89c55wd,74165,74164,74244,AT24c04.
Plz help on this logic family selection as i want to order new ics from FARNELL distributor.
I think with all the logic families pin diagram remains same.
Whether PCB designing changes with Logic Family of IC?
Cheers....Vishal.
