Hi all, I have a few 74HC240N (3 state, inverting octal buffer) and similar chips, as well as a MAX3070E (RS232 to TTL signal converter) in my design. Do I need to put 0.1uF bypass capacitors from Vin to GND near each of these chips? What would happen if I don't? I know I probably should, but somehow, I'm 1000/1000 pins max on my license of Diptrace and I can't place another pin, and it's becoming a pain in the ass to add these capacitors. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
