This is the video of the 2-to-9 Binary Up Counter. This is cause it only has a clock that counts up and since the MSI chip is synchronous you can not make it count down. These four pins accept the input data, if we wish to set the counter to a certain number using the LOAD’ pin.

It was actually very easy to modify the count once I got the concept of the MSI counter.

This is kc video of the 6-to Binary Up Counter. Analyze the counter shown below to determine the counters lower and upper count limit.

The way it works is pretty simple. This is the 4-to Binary Up Counter Video. Test iv simulate the circuit and verify it works as expected. Replacement Transformer Started by 74913 Today at 7: To participate you need to register. A disadvantage about the IC is that it only counts up cause u cant change the parts in the inside of the IC.


This gives us the binary number of so the count will start at 1. But as we learned from the lesson the 74LS has a Asynchronous load which means that when it counts down it adds a number so instead of having the count restarts at 5 it restarts at 6.

As we learned the has a input called a load and it is loaded with a binary count from the ABCD Inputs. It works according to the design and the probes show the binary count that goes into the HEX display.

Datasheets, Manuals or Parts. Please note that I made a mistake in the video and said the circuit uses a but it actually uses a 74LS IC. Their is a big difference between a synchronous and asynchronous load inputs. The probes show the binary count that 7413 into the HEX Display.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Washing machine trip the breaker Started by sew Today at 1: If you’re going to only use one clock pin, tie the other to ground.


The synch’d counters are set up so that one clock pulse drives every stage. Q a jc the low order bit, Q d is the high order bit.

74LS193 IC – Binary Up/Down Counter with Clear IC (74193 IC)

What are the advantages of implementing a synchronous counter with the 74LS integrated circuit versus using discrete flip-flops and gates? This is the 4-to Binary Up Counter that I had to make by modifying the counter.

Use the 74LS to create a Binary up counter. The 74LS is obviously the best choice cause its flexibility. As always, it’s a good idea to tie any input pins we don’t want to use to GND. Welcome to our site! This is a Clear pin, which will instantly reset all the outputs to LOW, or 0. A counter chip comes with a fair number of features on it.
