Below is a video log outlining the key features of the MSI Synchronous Logic Gates 74LS163 and 74LS193. It also contains examples of the circuits completed in assignments 3.3.2 and 3.3.3.
Conclusion Questions
- What are the advantages of implementing a synchronous counter with the 74LS163 integrated circuit versus using discrete flip-flops and gates? Using the MSI 74LS163 is preferable over flip-flops and gates because it uses less gates and wires thus maximizing efficiency. It is also easier to understand and utilize within a design.
- Disadvantages? The one thing about 74LS163 integrated circuits that is worse that using flip-flops and gates is that the integrated circuit cannot count down. The flip-flops are extremely basic and thus easy to manipulate and utilize in variety of situations, whereas the integrated circuit can only carry out its one job. Granted it does this very well.
- What are the advantages of implementing a synchronous counter with the 74LS193 IC over the 74LS163? What is the difference between a synchronous load input (i.e., 74LS163) and an asynchronous load input (i.e., 74LS193)? Using a 74LS193 is preferable over the 74LS163 because it has the ability to count both up and down. However, one difference that may be considered a disadvantage of the 74LS193 is that due to it being an asynchronous load input one must remember to set the count to reset on the number after the number they last wanted to display (i.e. upwards I wanted to display 7 and restart at 2, I would need to have it reset at the binary equivalent of 8).
