MOS and CMOS, are based on field effect transistors. Furthermore, in order to see how these different logic gates work, they will be used in separate circuits and have their own truth tables, so that it is easier to tell how they differ from each other, and how they would work. These logic gates perform the basic Boolean functions, such as AND, OR, NAND, NOR, Inversion, Exclusive-OR, Exclusive-NOR. Finally, we connect both of Finally, we construct another circuit using 5V DC Power, 7408 (AND gate), 2 SPDT Switches and a ground. <> TTL ICs are usually distinguished by numerical designation as the 5400 and 7400 series. Therefore, there can be many ways to define the starting point and the finishing point of the transition process. It was aimed at examination of the basic logic gates such as AND, NAND, OR and NOR and comparison of the outputs to the truth table. endstream For example, for AND gate when both inputs are true 1, the output is also true 1. This basic logic gate is the combination of AND and NOT gates. Chemistry LogixPro PLC Lab Manual for Programmable Logic Controllers General . )-560!'3!6'728!7-)0( ! Observe the output on a scope. The Boolean expression of AND gate is Y = A.B. In part one, we used a NOT Gate and found the output voltage in two ways. The common ones are; Additionally, these gates can also be found in a combination of one or two. Fan-outspecifies the number of standard loads that the output of a gate can drive without impairing its normal operation. %PDF-1.7 When drawing a truth table, the binary values 0 and 1 are used.
