Circuit 74HCT597

  1. Jan 9, 2010 #1
    Hello,

    I want to study about an Electronic Circuit Component, I need answer for these questions :

    Figures 1 and 2 below show that we can decompose 74HCT597 the circuit into two parts
    distinct (2 circuits in 1).

    Figure 1:

    Figure 2 :
    2.jpg

    What is the function performed by each of these parties?
    Justify the use of two circuits 74HCT597 to acquire input data.

    what is the role of the RCK input of storage register.
    what is the role of input /SRCLR, SRCK and /SRLOAD the shift register.
    What does the SER input of the first cell of shift register?

    Welcome to PhysicsForums!

    When trying to decipher the operation of an IC (in this case, a shift register), one of the first (and often the best) places to go is the datasheet:

    You can find a truth table as well as a timing diagram within the datasheet which should allow you to decipher the operation of the shift register and answer your questions. Here at PhysicsForums, we can't give you answers to homework, but will try to help you through them.

    If you don't have much exposure to shift registers, here's the Wikipedia article:
