Witryna19 mar 2024 · 3.5: TTL NAND and AND gates. Suppose we altered our basic open-collector inverter circuit, adding a second input terminal just like the first: This schematic illustrates a real circuit, but it isn’t called a “two-input inverter.”. Through analysis, we will discover what this Circuit’s logic function is and correspondingly what it should ... Witryna4 wrz 2007 · NAND gates is more preferred than NOR gates because of sizing. NAND is NMOS in series and PMOS in parallel, while NOR is the other way around. As people have already mentioned, the mobility of hole is less than that of the electron. Therefore, to achieve the same delay (current capability), PMOS needs to be approximately 3 …
