I connected one output (pin 1) of a cd4040 to the clock input of another cd4040. I am driving it with a 32 khz oscillator using a Schmidt trigger. I am using pin 6 and pin 9 as output of the second cd4040 and joining them with an or gate to produce two pulses per second and one pulse every 2 seconds. The problem is the rate seems to double sometimes when I power it on and I don't know if there's an anomaly with the cd4040. I want to drive a clock with it that is not usually driven this way where it would pulse two times per second and once every 2 seconds and this should keep the 60 count per minute. Somehow I feel my mind is affecting the count of the cd4040 and I don't know why it behaves this way.
