When the power is turned on, the output that goes to the high Iogic Ievel is not necessarily the output To guarantee that when the power is tumed on the counting begins from the output “0" going to the “1 " state and aII others remain at the configuration shown here is recommended The resistor may assume values between 10 k ohm and 100 k ohm and capacitor values between 0.01 µF and 0.47 µF. The maximum input frequency is 5 MHz when the circuit is powered from a 10 V source.
