A very early CD4029A counter IC, in 16-pin ceramic dual in-line package (DIP-16), manufactured by RCA Colorized IC die and schematics of CD4011BE NAND gateThe 4000 series was introduced as the CD4000 COS/MOS series in 1968 by RCA [1] as a lower power and more versatile alternative to the 7400 series of transistor-transistor logic (TTL) chips.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...

Commerce Secretary Gina Raimondo said 20% of "leading edge logic" chips can be made in the US by the end of the decade. The US currently makes 0%. Biden wants the US to make 20% of all high-end ...
A decade counter may have each (that is, it may count in binary-coded decimal, as the 7490 integrated circuit did) or other binary encodings. A decade counter is a binary counter designed to count to 1001 (decimal 9). An ordinary four-stage counter can be easily modified to a decade counter by adding a NAND gate as in the schematic to the right.

The Schmitt trigger was invented by American scientist Otto H. Schmitt in 1934 while he was a graduate student, [1] later described in his doctoral dissertation (1937) as a thermionic trigger. [2] It was a direct result of Schmitt's study of the neural impulse propagation in squid nerves. [2]
