Hi guys,

I have a dude about the capacitors and resistances that are used in the output of a logic circuit as a latch.
I think that they are used to modify the propagation time or the fanout of the gates but Im not sure. what can do a resistance in serie in the output and a capacitor to ground in the output of a latch?

Thanks.
 

Qetion is -dimensions?
You can have as a so called "AC-Termination"; Zzero is your resistor & a cap. in seri as DC block on your frequency...
Or you can it apply as an AC Load

Added after 2 minutes:

If the R-C elements are as an "L" part realised(R is between the 2 logic ICs & C is practically II on Input of second IC):
Because the edges are some slower after your RC-Circuit_ this is a delaying circuit/lowpass filter
