I recently purchased a very old synthesizer that uses CI HCF4060BE and I want to know if it is the memso that CI 74HC4060.

To help here is the CI datasheet HCF4060BE: LINK

Here the dataset of the CI 74HC4060: LINK

Here the base circuit of the synthesizer IC HCF4060BE: enter image description here

One of the IC's burned out (it was a problem in the voltage regulator and one track that feeds the other CIs was broken saving the other ICs HCF4060BE). I am very doubtful because this 74 ... works with 5 or 6v at the most, would that be a problem? why the filter circuit also works with 15v

Thank you all for helping me. I am a hobbyist and I understand the basics of circuits like this so I sent this question.

No. It will not work, as a quick look at the data sheet would tell you. Specifically this table:

enter image description here

The CD40xx CMOS family has a wide range of operation voltages. The 74XXxxx families are 5V at most (except for specialized driver ICs).

But for that reason you can still find plenty of CD4000 & CD4000B series ICs in the market. Even in through-hole packages. The CD4060 is no exception. Both Digikey and Mouser has them by the truckload.

  • \$\begingroup\$ I understood, thanks for the answer, it's that I live in Brazil and it's very difficult to find it. no physical store has it or the internet here in Brazil. \$\endgroup\$ – Gabriel L S Saraiva Feb 6 at 3:21
  • \$\begingroup\$ I'm going to study importing via Mouser, because I think he has business with Brazil. \$\endgroup\$ – Gabriel L S Saraiva Feb 6 at 3:23

    \$\begingroup\$ We are not supposed to promote any particular vendor, however mentioning several of them gets around that issue. There is also Newark and Allied. +1 for a quick, to the point answer. \$\endgroup\$ – Sparky256 Feb 6 at 4:10
