I
have two C005 timer chips.
Each chip works as a one-shot timer.
Trigger: active LOW.
During timing, OUTPUT = HIGH.
When timing ends, OUTPUT changes to LOW.
My idea is to cross-connect them:
Output A → Trigger B
Output B → Trigger A
At power-up both triggers are pulled HIGH. I manually trigger Timer A once.
My question is:
Will this oscillate indefinitely, or does the C005 require the trigger input to return HIGH before accepting the next falling edge?
Has anyone actually tested this?
