It seems that the HC series CMOS part 74HC(T)00 from the late 1980s is now the cheapest single-quantity equivalent coming in at about 30 cents. A quad 2-input NAND gate is hardly the most exciting ...

Any typical digital design style with CMOS uses complementary pairs of p-type and n-type MOSFETs for logic functions implementation. Naturally, CMOS always ought to provide INVERTED outputs like ...
