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 ...

and you can use A as input 1 and C as input 2, with the gate working as a two-input CMOS NAND gate. Output Y is also high when Q3 is opened and Q1 and Q2 are conducting. The output is low when Q5 ...

Introduction to CMOS circuits including transmission gate, inverter, NAND, NOR gates, MUXEs, latches and registers. MOS transistor theory including threshold voltage and design equations. CMOS ...

Looking at the NAND gate, we see that it requires four transistors and that the output remains on as long as at least one of the inputs is off. This same principle is used to design more advanced ...
