The 4000 series is a family of CMOS logic integrated circuits that became industry-standard components for digital logic design. Introduced by RCA in the late 1960s as the "COS/MOS" series, these devices offer low power consumption and wide operating voltage range compared to contemporary bipolar logic families. The 4000 series includes basic logic gates, flip-flops, counters, and other digital building blocks that remain relevant for many applications today.
This series is particularly noted for its:
The 4000 series finds use in numerous digital applications, particularly where power consumption is a critical factor:
The 4000 series is available in several standard package configurations:
The 4000 series follows standard industry part numbering conventions:
Example order codes:
Proper decoupling is essential for reliable operation:
CMOS inputs must never be left floating:
