The LMC555 is not a 555. It is a completely different chip that just happens to behave exactly like a 555. I am talking about a 555. A 555 is just a TTL chip.
It is exactly the same as all the TTL 7400 series. None of the 7400 are CMOS. But a 74cxxxx is a CMOS version of a TTL chip and performs an almost identical function but possibly not to the same high frequency of the TTL version, but consumes less current.
The original poster had a heading on this article: "555" This means just the 555 TTL timer chip.
He should have written "555 TTL timer and 7555 CMOS Timer."
Do you just like to argue, is that your thing? below is directly from the data sheet.
The LMC555 is a CMOS version of the industry standard
555 series general purpose timers.
You do speak English do you not?
