Actually bus is set of wires so why not use wires in place of bus . As you said I tried but Mike said I don't need to use hc244.I don´t think you need the 74HC244s at all, because the 74HC173 already has a tri-state output controlled by the OE pins, and also has input enable on the E pins.
Normally you would have an input bus connected to inputs of all your registers, and an output bus connected to all outputs from those registers.
All you need then is one 74HC244 that makes the connection from the output bus to the input bus, to allow you transfer contents of one register into another.
I don´t really undestand. I don´t care if the four data wires are bundled in a bus the way your program shows it or are standalone four wires, it still is a bus.Actually bus is set of wires so why not use wires in place of bus . As you said I tried but Mike said I don't need to use hc244.
HelloI totally agree with kubeek. In your first post you do not say what function you want the circuit to perform.
