Devices included in this entry:

RCA CD4012AK dual four-input NAND gate (14-pin planar DIP; pictured in thumbnail)
RCA CD4019AK multiplexer (16-pin planar DIP)

The RCA CD4000 series is generally considered to be the first complete family of CMOS logic circuits, and includes functional equivalents of many TTL devices. Despite the much lower power requirements of CMOS, SSI TTL vastly outperforms SSI CMOS in terms of speed, and the CD4000 series does not offer large-scale integration, the primary advantage of a matured MOS technology.
