  1. Lab 1. Introduction Presenter: Chun-Hsien Ko Contributors: Chung-Ting Jiang and Lin-Kai Chiu Dept. of Electrical and Computer Eng., NCTU

  2. Outlines • What is IC (Integrated Circuit)? • Basic Logic Operator: AND, OR, NOT • 74-series ICs: 7408, 7432, 7404 • Tools and Devices • Broad Board, Solid Conductors and Wire Strippers • Power Supply: +5V and GND • LED (Light-Emitting Diode) • Lab 1: DEMO the functions of ICs Dept. of Electrical and Computer Eng., NCTU

  3. What is IC (Integrated Circuit)? • 集成(Integrated)電路(Circuit) • What is circuit: resistance, capacity, bipolar • Inventor: Jack Kilby, 1923－2005 • Put all components in a chip • 7/16 in.=1.11 mm First integrated circuit, 1958 (1 bipolar, 3 resistances and 1 capacity) Dept. of Electrical and Computer Eng., NCTU

  4. Basic Logic Operator: AND, OR, NOT • NOT gate or INVERT (B = ~ A or B = A) • AND gate (Q = AB) • OR gate (Q = A+B) A B Dept. of Electrical and Computer Eng., NCTU

  5. Simulator: CEDAR logic • https://sourceforge.net/projects/cedarlogic/ • https://www.youtube.com/watch?v=4jFuGJgoPHU • Three basic components: • Inputs / Outputs • Logic Devices • Connections Dept. of Electrical and Computer Eng., NCTU

  6. Logic devices 2 input AND gate Inputs/ Outputs Dip switch GND LED Vcc RED: 1, BLACK: 0 Dept. of Electrical and Computer Eng., NCTU

  7. 74-series ICs • The lists of 74-series ICs: • https://en.wikipedia.org/wiki/List_of_7400_series_integrated_circuits • Logic High and Low • The ID of PINs Dept. of Electrical and Computer Eng., NCTU

  8. 7404 7408 7432 Dept. of Electrical and Computer Eng., NCTU

  9. Broad Board The slots under red line are common voltage Dept. of Electrical and Computer Eng., NCTU

  10. Solid Conductors • Wire Strippers Dept. of Electrical and Computer Eng., NCTU

  11. LED (Light-Emitting Diode) • + : long pin (connect to result) • - : short pin (connect to GND) • Logic 1 : bright • Logic 0 : dark • Debug: Logic 0? No signal? LED is broken? • + : long pin (connect to VCC) • - : short pin (connect to result) • Logic 0: bright • Don’t directly connect VCC and GND for a long time ! Dept. of Electrical and Computer Eng., NCTU

  12. Lab 1: DEMO the functions of ICs Dept. of Electrical and Computer Eng., NCTU
