The '''4000 series''' is a [[CMOS]] [[logic family]] of [[integrated circuits]] (ICs) first introduced in 1968 by [[RCA]].<ref name="CH_CMOS">{{cite web |title=1963: Complementary MOS Circuit Configuration is Invented |url=https://www.computerhistory.org/siliconengine/complementary-mos-circuit-configuration-is-invented/ |website=[[Computer History Museum]] |archiveurl=https://web.archive.org/web/20190723142758/https://www.computerhistory.org/siliconengine/complementary-mos-circuit-configuration-is-invented/ |archivedate=July 23, 2019 |url-status=live}}</ref> It was slowly migrated into the 4000B buffered series after about 1975.<ref>{{cite web |last1=Marston |first1=Ray |title=Understanding Digital Logic ICs - Part 4 |url=https://www.nutsvolts.com/magazine/article/understanding_digital_logic_ics_part_4 |publisher=Nuts and Volts |archive-url=https://web.archive.org/web/20161101080115/https://www.nutsvolts.com/magazine/article/understanding_digital_logic_ics_part_4 |archive-date=November 1, 2016 |date=October 2006 |url-status=live}}</ref> It had a much wider supply voltage range than any contemporary logic family (3V to 18V recommended range for "B" series). Almost all IC manufacturers active during this initial era fabricated models for this series. Its naming convention is still in use today.
