The 4000 series was introduced as the CD4000 COS/MOS series in 1968 by RCA as a lower power and more versatile alternative to the 7400 series of transistor-transistor logic (TTL) chips. The logic functions were implemented with the newly introduced Complementary Metal–Oxide–Semiconductor (CMOS) … See more The 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. It was slowly migrated into the 4000B buffered series after about 1975. It had a much wider supply voltage range than any … See more Logic gates Flip-flops • 4013 – Dual D-type flip-flop.

WebIn networking, time to live (TTL) determines how long to cache either a query or content. The TTL meaning differs based on the kind of TTL being described. As you learn what TTL means, you have to differentiate between Domain Name System (DNS) TTL and content delivery network (CDN) TTL. DNS TTL instructs the DNS resolver as to the amount of ...
