Hi, Ant. It depends. You have to look at the data sheet to see if a
very slow-rise reset is OK for your chip. This will take dozens of
milliseconds to go through the intermediate area between logic "0" and
logic "1", which might be a problem for the reset circuitry internal to
your chip. Look on the data sheet for maximum reset pulse rise and
If it is a problem, or if you're not sure, and you have a spare
inverter gate and no time to research, it might be just best to reverse
the R and C, and then use the inverter to square it up anyway. No
points off here. The hysteresis of a 74HC14 can be invaluable for
this. If I need an inverter on a board, I'll spec one of these so I
can have this squaring up capability.
Good luck with your project. I hope things are going well.
