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 ...

One of the things that every student of digital electronics learns, is that every single logic function can be made from a combination of NAND gates ... PCB-based design. TTL and CMOS logic ...

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 ...
