Betreff: Re: [TekScopes] Re: Need MC4035P chip for a DC503
Luis is absolutely right. I am pretty sure that the design of the
DC503 was
before 4000 series of CMOS was invented.
Can somebody confirm this? Is this design THAT old?
Yes the chip design is more than 35 years old.
It appears in my Motorola TTL Integrated Circuits Data Book, First
Edition of 1971
