[simpits-tech] RC Timer delay

[Stig Joergensen]

Hi Gang,

I need some help here. I need to calculate the time for RC (resistor
-Capitor) delay circut. I know the formula is t = r*c, but what are the
units?

more specific, consider the following :

strobe----|
        __|__
         cap
        _____
          |
          |----- out
          |
         | |
         |r|
         |_|
          |
gnd-------|


when stobe goes high, out will go high almost at the same time, but what
should the walues (r and c) be for out to go low, say 5 ms after strobe
drops to low again?
