i'm using a 4017 counter in a circuit and one output (pin 5) is connected to 5 inputs of 5 ics. (one 74HC00, one 4052 , two 4026s and the enable pin of the same 4017 (pin 13)). when using it practically the voltage at the output pin 5 is set low. thus it doesn't work properly. could it be because fan out? i tried a opamp buffer bt it also doesn't work. would a 4050 buffer would do? does anyone know what could be done to solve this problem? thankyouu!!!
