Wikipedia has related information at series. Wikimedia Commons has media related to: The series is a popular set of logic ICs that can be ordered from many vendors, and used in many applications.
There are exceptions like the Wikipedia has related information at logic family. Each chip has its name printed on top for example, “74HC”describing its logic family and digital logic functionality.
The output pin is high icc when either one, or both, of the input pins are high.
The output pin is low only when either one, or both, of the input pins are high. The output pin is low when both input pins are equal both high or both lowand it is high when one of the input pins is high and at the same time the other input pin is low.
This is called the “odd but not even gate” meaning that an odd number of inputs need to be high in order for the output to be high.

The XNOR gate is just the opposite; called the “even but not odd gate”. The output pin is high only when all input pins are high at the same time.
The output pin is low only when all input pins are high at the same time.
When designing new digital circuits, we may sketch dozens of slightly different kinds of gates —different numbers of inputs, etc. Just about every kind of gate you can imaging has been manufactured somewhere.
However, when it comes time to actually construct a circuit, we typically use only a few kinds of “common” chips rather than every possible chip.
The Apollo Guidance Computer is an example of an entire computer out of only one kind of gate.

If our sketch includes a 4-input AND gate, you might think we would simply grab a off the shelf and wire it up. This is rare in actual practice. It is far more likely that we will do one of:. Very wide gates say, a input NOR gate are typically implemented datahseet a handful of less complicated gates in a “tree” or “funnel”. From Wikibooks, open books for an open world.
