    I run the 4060B with recommended voltage of 3v. I want to know how to output the same voltage (3v) coming into the 4060B (vdd) Q4-Q4 output pins.

    I have options to increase the voltage from 3v, 4v and 6v. So if I increase the voltage going into the 4060B, say 4v, I want the same voltage coming out from the output pins Q4-Q14 to be 4v. Same with 6v coming in, and 6v coming out. Any ideas?

    As far as I see in the datasheet, when the pulses are HI, voltages come out at around 1v. If the outputs are LO, voltage is lower than 1v. I want to output the voltages at 3v, 4v, or 6v if I choose to.

    I don't know what part of the data sheet you were looking at but the high output voltage should be within 0.5 Volts of the supply voltage. The output low voltage will be approx. 0.05 Volts

    Thanks for the reply.

    Is there a way to add high or low voltage connection after the pulsing outputs from Q4-Q14 so I can pulse 2Hz, 4Hz or 8Hz based on the voltages I choose? Maybe a transistor could help do this? Im using a 9v battery for this project.

    My issue is I am trying to make frequencies pulse based on certain voltages. I am trying to avoid the 555 timer as much as possible because its not accurate. Frequencies from 2Hz, 4Hz or 8Hz I need to pulse on any voltages I switch the power to (3v, 4v or 6v). Do you know an IC for this?

    the LED's flashing from the outputs Q4-Q14 are just indicators that the frequencies are working. Thats all. my problem is I need those frequencies to work on voltages.

    Please let me know if I am not clear on this so I can clarify.

    If you can use the lower voltage set to 3 Volts then you could use the CD4060 and just adjust its supply voltage for what you need i.e 3,4,6,8 Volts. You can do this with a adjustable regulator by switching in different resistor values. Otherwise it gets a bit more complex.

    Thanks for the reply.

    My problem is adjusting the output voltages from Q4-Q14 which are HI at 0.5v and low at 0.05v. I need to somehow raise the output voltages from there to 3v, 4v and 6v. Does this require external components? If so, does a transistor work for this?

    I just learned that transistor/power transistor can do the trick.

    Thanks for helping!

    As Adam said, the Qn output voltages on a 4060 should swing all the way between VDD (when high) and VSS (when low). If you're only getting 0.5V at the outputs when they're high, you must have something loading the outputs down. Show us a schematic.

    He has stated in another forum he has LED's on the outputs with no current limiting resistors. He has been told this will clamp the output voltages at the Vf of the LED's.

    I second that.
