"Buffer" is taught in logic class, no?

    Where is the "Buffer?" "Buffer" is taught in logic class, no?

    I am just curious.

    A buffer is a type of logic chip that does nothing more than add additional power to drive more logic chips. That is, if the output of one chip must drive the input of more than 6 other chips, the current may not be sufficient. Therefore, a buffer chip is used to add more driving power.

    That really does not answer the OPs question which is imposible to answer. There is no way to know if a particular logic class teaches about buffers without having access to the class sllybus.

    By itself, "buffer" is a generic term indicating an amplifier with unity gain (Av=1). It can best be thought of as an impedance matching device or a current amplifier.

    Being a generic term a particular buffer may be designed for either digital or analog use.

    One will also see "inverting buffers" where the gain is -1.

    In general "buffers" do nothing for logic and are commonly left out of conversations or classes strictly about logical operations and binary math. They are only an electrical necessity so, the answer is, it depends on the course and professor. I could see both situations.

    There are such things as inverting buffer and non-inverting buffer.
