  1. Integrated Circuits •  Object / purpose: • To apply information about IC circuits in the design of various applications.

  2. Read the Handout or Listen to Lecture and take notes. • 1) The abbreviated term for Integrated Circuits is _____________________

  3. 2) An IC is a _______________________________________ •  3) ICs are popular because of ______________, _________________ • 4) Two commonly used IC packages are ______________ and ________________

  4. 5) ICs are classified into two basic categories • _________aka _____, numbered by ________ • _________aka ______, numbered by _______ • 6) TTL ICs are a little __________ to work with whereas CMOS can be damaged by ________________

  5. 7) ICs use the same basic logic and materials as Transistors accept they are built by __________________. • 8) What is the acceptable voltage for a TTL IC? _____________________________

  6. 9) List the names of the 8 pins on a 555 IC timer and describe its usage • Name Usage • 1 __________________   • 2 __________________   • 3 __________________   • 4 __________________ • 5 __________________ • 6 __________________ • 7 __________________   • 8 __________________  

  7.  a) Define the following terms below • TTL CMOS IC Packet Notch/dot IC Pin # • b) Draw the Pin Out Schematic of a 555 IC circuit, define and number each pin.

  8. 2) Draw and then Build project 1 Single Oscillator

  9. 3) Draw and then Build project 2a “Rail Road” lights

  10. 4) Change project # 2a into project # 2b “Variable lights” • In a short paragraph describe the essential changes that were made and what pins were effected and why. Use the terms threshold and discharge in you answer.

  11. 5) Draw and then Build prjt # 3a “Audio Generator”  • Answer: why is the Transistor in the circuit?

  12. 6) Change project # 3a into project # 3b “Wake-Up Alarm” • In a short paragraph describe the essential changes that were made and what pins were effected and why.

  13. 7) Draw and then build project # 4a “English Police Siren” • What makes the tone change?

  14. 8) Change project # 4a into project # 4b • What is a double oscillator? • In a short paragraph describe the essential changes that were made and what pins were effected and why?

  15. 9) Draw and then build either one of the two projects #5A and #5B (your choice) Work with another student so you build one and s/he builds the other. • In a short paragraph describe how projects #5A and #5B are different.
