Integrated Circuit 74LS164
Through a few of my previous articles I have tried to cover the working principles of a couple of versatile ICs like the and Unlike ordinary CMOS ICs which has also been discussed in many of my previous articles , the above ICs are equipped with many different built-in features which may be accessed or activated by just applying the appropriate logic inputs or components to their relevant pin-outs. Similarly the IC requires only an external clock signal to make its outputs swing into action and produce interesting logic sequences. Referring to the figure on the left we see that externally it looks just like an ordinary pin dual in-line chip. The extreme top left pin from the printed side is the first pin in the order, and the pin just opposite to it on the other row is the last or the 14th pin. The serial inputs pin 1 and 2 of the IC has a special purpose of resetting the above procedure in an interesting pattern.
