AVTE 316 - 2C Midterm Examination

Which of the following is an output pin?

• pin 8 of 4071

• pin 12 of 7404

• pin 4 of 4081

• pin 6 of 7432

This is an output pin for 7411 IC.

• 12

• 9

• 8

• 6

This gate produces a low output if both inputs are high.

• NAND

• NOR

• NOT

• XOR

This gate produces a low output if both inputs are low.

• AND

• OR

• XOR

• NOT

Which of the following is a NAND gate IC?

• 7412

• 7420

• 4012

• 4073

Which of the following is incorrect regarding OR gates?

• F = 1 if A = 0 and B = 0

• F = 0 if A = 1 and B = 1

• F = 0 if A = 0 and B = 1

• F = 0 if A = 1 and B = 0

Which of the following is an AND gate IC?

• 4073

• 4072

• 7421

• 7411

Which of the following is correct regarding NOR gates?

• F = 0 if A = 1 and B = 0

• F = 1 if A = 0 and B = 0

• F = 0 if A = 1 and B = 1

• F = 0 if A = 0 and B = 1

Which of the following is incorrect regarding XOR gates?

• F = 1 if A = 1 and B = 1

• F = 0 if A = 1 and B = 0

• F = 1 if A = 0 and B = 0

• F = 0 if A = 0 and B = 1

The logic function F = AB'C' + A'B'C + A'BC' will have a high output on F if:

• A = 1, B = 1 and C = 1

• A = 0, B = 0 and C = 1

• A = 0, B = 1 and C = 0

• A = 1, B = 0 and C = 0
