Hello everybody i have posted time ago problems to generate frequency with the HC4060 and today i am back with another default on pin 1 2 3 are ok! the other ones have no signal and the circuit is connected on breadboard ! my frequency metter is a velleman dvm4100,
waiting for your opinions!
thanks

 

This is the circuit from the datasheet:

 

If pins 1,2,3 are giving the expected output then the oscillator is working, so it appears you either have bad connections in the breadboard or defective stage outputs. The IC is static-sensitive so subject to electrical damage if carelessly handled.

 

Alec t ok can the 110 VAC 60hz can produce anomaly near the circuit?

 

AlbertHall yes i have tried with the datasheet it doesnt work

 

By bread board, do you mean one of those boards with wires you push into pins in a matrix.

If so, you might have run into the crystal problem.
crystal oscillators are VERY dependent upon capacitance / inductance on their pins, 9 impedance )
these sort of bread boards have notoriously bad impedance,

You can easily stop one of these oscilators on a board by putting a finger near one.
on a bread board, your better off using an oscilator, not a crystal.

can the 110 VAC 60hz can produce anomaly near the circuit?

Possibly, if you have a setup with straggly wires (which act as antennae and pick up interference).

 

hi andrewmm! thank you for this point of view! so i will change my crystall 16mhz for an oscillator of same value on breadboard! do you have an example of schematic? can i put directly a cd4017 with?
regards

 

Alec_t ok thank ,you!

 

Check the data sheet for the 74HC40xx series, to determine whether they can be toggled at 16 Mhz.
Plain CD40xx have a much lower frequency limit.
