Out of all the basic logic gates, the NAND gate is the very convenient one. It is because, by using any combinations of NAND gate, the output of any logic can be seen. A NAND gate is the representation of NOT AND. The logic gates look similar to each other. So, when purchasing one, make sure to follow these guidelines.
Look for the proper logic Gate number
There are two standard designs for logic gates. They are CMOS and TTL. In the standard 4000 series, the IC number of the NAND gate is 4011. In the TTL, the 74 series has a wide standard of NAND gates. Since all the gates look alike, there are chances of buying the wrong one. Hence, always look for the proper IC number.
Number of inputs in NAND gate
Generally, in a NAND gate, there are four types of inputs available. They are 2, 3, 4, and 8. There are no specific reasons to select the number of input types. The higher the number of inputs, the more complex it can get. However, for the circuits that need many numbers of inputs, choose the one with the higher one.
Other specifications that matter
Look for the overall dimensions of the logic gate. Also, make sure that the pins are new and sturdy. When used In PCB with continuous removal, then the pin weakens. Hence, look for sturdy material in pins of the gate. The size of the NAND gate differs with the number of pins.
Various applications to be used
There are various uses and applications for the NAND gate. The most common examples in real-life are burglar alarms and freezer warning alarms. It has so many other applications too. There are many more applications too. So, choose the NAND gate that is suitable for the need.
