In this lab you will perform some of the experiments listed in Chapter 11, Sections 0 through 2 in your text book.
You may perform experiments not listed in the book. However, you must first discuss them with the instructor and have a clear objective and expected result in mind.
Check-out the following equipment from the Technical Support Center at the beginning of the period.
| 1 | Digi Designer |
| 1 set | Wires (should come with Digi Designer) |
| 1 | Logic Probe |
| 1 | Logic Pulser |
| 1 set | Alligator clips |
| 1 | 74x00 Quad 2-input NAND chip |
| 1 | 74x01 Quad 2-input open collector NAND chip (optional) |
| 1 | 74x02 Quad 2-input NOR chip |
| 1 | 74x03 Quad 2-input open collector NAND chip (optional) |
| 1 | 74x04 Hex inverter chip |
| 1 | 74x08 Quad 2-input AND chip |
| 1 | 74x32 Quad 2-input OR chip |
| 1 | 74x86 Quad 2-input XOR chip |
| 1 | 74x93 4-bit counter chip |
Read sections 11-0 through 11-2 before starting. Complete the corresponding section of the answer sheet before moving on to the next part. Don't forget to connect the power and ground to all your chips and to turn on the Digi Designer.
Use all chips from the same logic family (L, S, H, etc.) if possible. Do not use type N chips.
Perform the experiments under the blue "Truth Tables" heading on page 444 in your text.
Perform the experiments under the blue "Binary Count" heading on page 441 in your text. Remember to use the Chop mode on the oscilloscope to assure the phases of your signals are displayed properly.
Perform the experiments under the blue "BCD Count" heading on page 442 in your text.
Perform the experiments under the blue "Waveforms" heading on page 444 in your text. Display the low order bit (QA) and the gate output. Do only NAND and NOR chips. You may want to run your circuit at a low clock freqency and use the Digi Designer LED rather than the oscilloscope.
Perform the experiments under the blue "NAND Circuit" heading on page 445 in your text.
You may investigate TTL wired-AND operation using 74x01 or 74x03 chips. See the 74x01 and 74x03 data sheets and pages 413-6 in your text.
