Logic Gates

Question 1

What is the algebraic equation of the NOT gate?

Answer 1

Y = YNOT

(One side must be on, NOT the other)

Question 2

What is the algebraic expression of the AND gate vs the OR gate?

Answer 2

AND: AB
(One side AND the other must be on)

OR: A + B
(One OR the other, at least must be on)

Question 3

What is the difference between how each gate works (on/off)

Answer 3

NOT: Only one side can be on for the circuit to work
(One side, NOT the other)

AND: BOTH sides must be on for the circuit
(One side AND the other) (1x0)=1

OR: One side OR the other must be on at least (1+ 0= 1)

Question 4

What is the chip number of each logic gate?

Answer 4

NOT: 7404
AND: 7408
OR: 7432

Question 5

How many gates are there in each type of logic gate?

Answer 5

NOT: 6 (input into one side, and out the next)
AND: 4 (input into 2 sides, and out one)
OR: 4 (input into 2 sides, and out one)

Question 6

How many pins are on a logic gate?

Answer 6

14, but one is used to be plugged into the positive rail (power), and another to the negative rail (ground)

Question 7

What is the chip number of a not gate?

Answer 7

7404

Question 8

What is the chip number of an and gate?

Answer 8

7408

Question 9

What is the chip number of an or gate?

Answer 9

7432
