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 ...

1 NAND inverting gate and AND non-inverting gate Standard CMOS gates used in IC design are inverting for ... an inverter when the inversion can be optimized away in the logic by using an inverting ...

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 ... TTL and CMOS logic chips made their ...
