A A' Introduction In this lab, the expected learning objectives were to understand the results of improper wiring practices and the functionality and wiring of a three-state and open-collection buffer. After the completion of the lab, I will understand how to use a voltmeter to take voltage readings, understand the thermal and electrical principles of using two conflicting out signals, and understand the ways that three-state and open-collection buffers operate and how to build them. Experiment Results Task 1-1: Effect of Missing Input to TTL Gates Task 1-1: Task Statement In the task, I was asked to set up a regular NOT gate with an input and have an output connected to and LED. I was also asked to take voltage readings for the input and output. I was then asked to disconnect the input and see what effect that had on the voltage readings. Task 1-1: Work Preformed For this task, I connect an input and output to a NOT gate as one would usually do. I then used the voltmeter to take the voltages of the input and output for both input possibilities. The setup is seen below in Figure 1. The voltage readings are seen in Table 1. Figure - Circuit Diagram of NOT Gate A A’ .069 V 3.847 V 5.047 V .011 V Table - Voltage Readings for NOT Gate I was then asked to not connect and input to the NOT gate and record the voltage readings. The setup is seen below in Figure 2. The voltage readings are seen in Table 2.

A A' Figure - Circuit Diagram of NOT Gate without Input A A’ .001 V .001 V Table -Voltage Readings for NOT Gate without Input Task 1-1: What I Learned In this task, I learned that if you do not connect and input to a TTL IC, that it will function as if the input supplied was a zero. However, I also learned that is not a good practice and should not be used to cut corners for less wiring. Task 1-2: Observer How Hot a Chip Gets Task 1-2: Task Statement In the task, I was asked to use the back of my finger to determine how hot an IC gets when it is in use. Task 1-2: Work Preformed For this task, I kept the same setup as Task 1 and used my finger to determine how hot an IC gets when it is in use. I touched the IC and would say that is gets slightly warmer than when not in use. Task 1-2: What I Learned
