3.3.2 MSI 163 Synchronous counter
1. Advantages of the 74LS163 over just flip flops.
The 74LS163 Integrated Circuit is a synchronous parallel circuit therefore it has no ripple effect like regular flip flops. 2. Disadvantages to the 74LS163. The 74LS163 cannot be used as a down counter. 3. Analyze the counter and determine the lower and upper count limit. The counter starts at 1 and counts until it reaches 9 then resets. |
3.3.3 MSI 193 Synchronous Counter
1. Advantages to the 74LS193 over the 74LS163
The 193 is able to count down, the 163 is unable to do that, also it is much easier. 2. Difference between a Synchronous Load Input and an Asynchronous one? In a synchronous circuit there is no ripple effect, because it is all parallel, an asynchronous circuit will have a ripple effect because it is in a series and not everything is happening at the same time. 3. Analyze the counter and judge the upper count limit and the lower count limit. The counter will start at 9 and count down to 1. |
