1 Transistors as Digital Switches: Intro to Logic Gates Circuits that really count

2 Operation in Saturation and Cutoff

3 Binary/Digital Representation Digital “1” = +5 V = high Digital “0” = 0 V = low

4 Inverter (NOT logic gate)

5 NAND gate

6 Design an OR gate ABY 000 101 011 111

7 NOR gate

8 Exclusive OR (XOR)

9 Logic Gate Library

10 Digital combos Green LED illuminates when proper code is entered. Ready, set crack the code!

11 Teddy KGB’s Oreos Stash

12 And now, your joke of the day There are only 10 types of people in the world. Those who understand binary, and those who don’t.
