CD74HC4060: Is it possible to use CD4060 make a 4 hours delay switch

Part Number: CD74HC4060

I would like to make a 4 hours delay circuit.

Is it possible to use CD4060 or some logic circuit to realize this function

  • Hi,

    To accomplish this you would need to set an appropriate clock signal to ensure the counter will count for 4 hours. Using this device, however, will not ensure an accurate timer. If you decide to go this route, we recommend an external 3 inverter oscillator, such as using 3 channels of the SN74LVC3G04 to increase the accuracy of the delay. You may also want to use two counters in series to increase the frequency of the clock needed into the MHz range.
