5. What is this? AND

6. AND gate Input A Input B Output (Q) 1
Produces an output only if both inputs are on
Input A
Input B
Output (Q) 1

7. Can you draw a circuit that would act like an AND gate?

9. OR Gate Input A Input B Output (Q) 1
Produces an output when one or the other input are active….
Input A
Input B
Output (Q) 1

10. Can you draw a circuit that would act like an OR gate?

12. NOT Gate Input (A) Output (Q) 1 A NOT gate inverts its input1
could play the opposite game?

13. Can you draw a circuit that would act like an NOT gate?

14. Some extras to fry your brain

15. NAND IS AN “INVERTED AND GATE”

16. NOT AND = NAND
Input A
Input B
A.B
Output (Q)=A.B 1

17. Can you draw a circuit that would act like an NAND gate?

18. A NOR gate is simply an inverted OR gate.
Output is high when neither input A nor input B is high:

19. NOT OR =NOR
Input A
Input B
A+B
Output (Q) A+B 1

20. Can you draw a circuit that would act like an NOR gate?

21. An XOR gate is constructed similarly to an OR gate, except with an additional NAND gate inserted such that
if both inputs are high, the inputs to the final NAND gate will also be high, and the output will be low.

22. XOR – Exclusive OR
Input A
Input B
Output (Q) 1
