The output of an AND gate with three inputs, A, B, and C, is HIGH when ________.

• A = 1, B = 1, C = 0

• A = 0, B = 0, C = 0

• A = 1, B = 1, C = 1

• A = 1, B = 0, C = 1

If a 3-input NOR gate has eight input possibilities, how many of those possibilities will result in a HIGH output?

• 1

• 2

• 7

• 8

If a signal passing through a gate is inhibited by sending a LOW into one of the inputs, and the output is HIGH, the gate is a(n):

• AND Gate
• OR Gate
• NOT Gate
• NAND Gate

When used with an IC, what does the term "QUAD" indicate?

• 2

• 4

• 6

• 8

The output of an OR gate with three inputs, A, B, and C, is LOW when ________.

• At least one input is HIGH
• All inputs are HIGH
• All inputs are LOW
• At least one input is LOW

Which of the following logical operations is represented by the + sign in Boolean algebra?

• AND
• OR
• NOT
• XOR

Output will be a LOW for any case when one or more inputs are zero for a(n):

• AND Gate
• OR Gate
• NAND Gate
• NOR Gate

How many pins does the 7400 IC have?

• 14
• 16
• 18
• 20

The output of a NOR gate is HIGH if ________.

• both inputs are HIGH
• either input is HIGH
• both inputs are LOW
• either input is LOW

The format used to present the logic output for the various combinations of logic inputs to a gate is called a(n):
