As a digital designer, you will occasionally
need to redesign an existing circuit. In doing so, you will come across part numbers that you are not
familiar with. Use the Internet to identify the functionality and manufacturer of each of the part
numbers listed below. Note that many parts will have several manufacturers. For the purpose of
completing this table, list one. Also, do not print these datasheets. Simply view them online and
extract the necessary information.
a. | DM74LS75 | d. | SN74LS86 | b. | MAN6760 | e. | SN74LS02 | c. | DM74LS00 |

When you design a digital logic circuit, you
will often need a gate that performs a specific function. You may be unsure of its part number. Use
the Internet to identify the 74LS series part number for each of the following five gates. Again, do
not print these datasheets. Simply view them online and extract the necessary
information.

Throughout this course you will use an ever-increasing
list of integrated circuits. You will need to obtain datasheets for these circuits. Since the focus
of this unit is the Board Game Counter design, we will obtain the datasheets for each integrated
circuit used in this design. Using the Internet, locate the manufacturer datasheet for each of the
following integrated circuits. The connection diagram and function table of each IC is needed.
Therefore, print only pages 1 and 2 of each data sheet.
· 74LS04 Hex Inverter
Gates
· 74LS08 Quad 2-Input AND Gates
· 74LS32 Quad 2-Input OR
Gates
· 74LS74 Dual Positive-Edge-Triggered D Flip-Flops with
Preset and Clear
· LM555 Timer
You will use these when you are breadboarding. Write the word
“completed” without the quotes for your answer below once you have done
this.
