If you apply 12v to the ICL7660 you will likely burn it up.

If you don't exceed 10V, then there is no problem. If you exceed 10V, you will damage the part. What battery do you intend to use on the Minipulse?

12v

Only if you don't exceed 10V.

Only if you don't exceed 10V.

I mean, there is no problem if you use it

I have this available, is it enough?
ICL7660 up 10v

Thanks

I often use the STTH1L06.

Options for the charge pump:
ICL7660A (up to 12V)
ICL7662 (20V)
MAX1822 (16V)
LTC1044 (12V)
LTC1144 (18V)

You'll need to check data sheets to ensure suitability.

Please give alternatives to the Mur460 diode
Also alternatives to Lt1054

You cannot use CD4098 as a replacement unless you redesign the PCB because the pin-out is completely different.
By the way, the IC you are looking for is MC14538, not MC14358. There are some available in ebay.

Thank you.
I just saw the datasheet and since my suplier have the CD4098 i thought that those could be uses.
Thank you very much. I Will surely have a look on eBay then.
Regards.

friends, i'm not being lazzy, it's just that my usual suplier (Digi-key online + 2 local shops) don't have this MC14358BCP, it's identified as obsolete....
any one knows an alternative, or other suplier?
Thanks in advance.
best regards,

last question of the day...can MC14358bcp be replaced by CD4098BE?

Looks perfectly normal.

[Carl-NC]

It looks ok to me.
