Hey, Thank you for the reply.. We are using this circuit as a means to generate a frequency based on the conductivity sensor situated between Pins 1 and 5 of SN7414(Please refer the Dig. provided before). the output is taken from pin 4 which goes to the capture pin of our microcontroller. The problem we are facing is that even when the Sensor is kept floating, we are getting random frequencies at pin 4. And also, Even when the Conductivity sensor is kept in a stable Solution, we are getting fluctuating frequencies at the output. Therefore we would appreciate a component wise explanation for our application circuit and for a better understanding , a application design circuit for generating a 50Khz Frequency.
