Texas Instruments Digital Design Engineer Interview Questions and Answers

NOT gate is a logic gate that inverts the input signal.

• Also known as inverter gate

• Produces output that is opposite of input

• Symbol is a triangle with a small circle at the input

• Example: NOT gate with input 0 produces output 1

NAND gate is a logic gate that produces an output that is the inverse of the AND gate.

• It has two or more inputs and one output.

• The output is low only when all inputs are high.

• It is a combination of an AND gate followed by a NOT gate.

• It is commonly used in digital circuits for its versatility and efficiency.

• Example: CD4011B IC contains four 2-input NAND gates.

State time analysis is a method used to analyze the behavior of digital circuits over time.

• State time analysis involves creating a state diagram to represent the circuit's behavior.

• The state diagram is used to determine the circuit's output at each clock cycle.

• This analysis is useful for verifying the correctness of digital circuits.

• It can also be used to optimize circuit performance.

• Examples of tools used for state ti
