And Gate Ic. An and gate is a logic gate that gives a high output only when all its inputs are high. The function can be extended to any number of inputs.
The following is a list of 7400 series digital logic integrated circuits in the mid 1960s the original 7400 series integrated circuits were introduced by texas instruments with the prefix sn to create the name sn74xx. In other words for a logic and gate any low input will give a low output. An and gate operates on logical multiplication rules.
If all of the inputs are high 1 then the output will also be high.
Due to the popularity of these parts other manufacturers released pin to pin compatible logic devices and kept the 7400 sequence number as an aid to identification of. One of the most popular ic for and gate is 7408 which is a quad two input and gate ic which means that this ic contains 4 independent two input and gates. An and gate is a logic gate having two or more inputs and a single output. 74ls08 is a 14 pin ic.
