In order to know about the operation of an IC we need to learn how to use data sheets from the manufacturer.

74HC08; 74HCT08 Quad 2-input AND Gate

Before you come to your first laboratory Make sure you have completed the pre laboratory activity. The laboratory notes provide for you the data sheets for the ICs used in this experiment. If you require datasheets for other ICs in the future then a great place to find them are from online electronic websites such as Element To be able to understand how to use this chip we need to be able to read the manufacturers 74HC08N data sheet.


Click on the hyperlink or go to the data sheet section of the laboratory notes. Task 1 From the datasheet draw the following:.

After completing Task 1 we now know what type of gate is represented in the 74HC08N, as well as knowing how to connect the pins and its performance characteristics.

In section one we looked at the behaviour of basic logic gates using Multisim.

The beauty of Multisim is that it has a massive database of ICs from a large variety of manufacturers. Multisim tries to simulate the operating characteristics of these chips. In the component browser type datadheet ’74HC08N’.

Select the 6V component.

You will now see details about the chip in the ‘Component Browser’. Task 2 Within the Component Browser:. What information is provided? Within Component Browser select ‘OK’ to place the chip. A window will pop up allowing you to select a new chip datasehet 1 of the available gates within a chip. Note that once a logic gate is placed in the work area you have the ability to keep placing more logic gates until you close the ‘Component Browser’.

Now 74hc8n you have one component in place build the circuit below using the knowledge you have obtained so far:. Task 1 From the datasheet draw the following: We are now going to look at a very basic example of how to use this to our advantage. Task 2 Within the Component Browser: Now that you have one component in place build the circuit below using the knowledge you have obtained so far: You can change the keyboard assignment that controls a switch by right clicking on the switch and changing its properties.


Task 3 With the 74hc08 Analyser open click on the ‘play’ button to start the simulation. Try different combinations with the two switches and describe what occurs in the Logic Analyser display. The key to answering this question is to understand the relationship between the output signal and the clock signal. When do changes occur to the output signal in relationship to the clock? When you finish simulating your circuit do not forget to stop the simulation. You cannot make changes until the circuit has been stopped!
