I'm doing a small box that accepts a user trigger. I'd like to flash an LED every time it gets triggered. Something like 100 ms, on a blue LED.
The obvious circuit is a 74lvc1G123 one-shot, set to 100 ms pulse width. But how fast will that work? I'd like to go to 50 or maybe 100 MHz. Would it keep retriggering? I wouldn't want the LED to go out at high trigger rates.
There is a specified "retrigger time", but I'm not sure what that means. Has anyone really over-triggered these things?
I guess I could breadboard and try it, but asking is easier.
