I am looking for
NJU7660D Charge pump I found one at one site in stock however they have a $30 min order It appears this is a discontinued IC at digikey and mouser
There is a direct replacement for the ICL7660. It is the LT1054CN8 by Linear Technology and the LT1054CP by Texas Instruments.
If the starter of this thread is in the US and will send me a PM I be happy to send a couple first class mail.
NJR is New Japan Radio. Maybe they do not copy the American ICL7660 anymore.
Why not use the original one? Digikey has through hole, surface mount and maybe 100,000 of them in stock today.
