Title: Fear not the shmidtt trigger oscillator
Post by: blackbeard on January 10, 2011, 11:01:13 AM

Why do people use 555 timer chips all the time? A schmidtt trigger oscillator using a 74hc14 is simpler, cheaper, has 8 possible timers and runs at 5v so why do people use 555 timers?

Hi,

I guess size and drive potential are the most important reasons.
