Hi guys,
I'm trying to use a 7805 voltage regulator to drive these ICs:
Three CMOS logic gates (74HC04, 74HC08 & 74HC32).
Two 555 timers.
One 4066 (quad bilateral switch).
The output of the logic gates has excessive noise when i used 7805 supply but the noise is reduced when I use a fixed 5V power supply.
Any ideas on what's causing this distortion?
