Which is not a characteristic of logic families

Answer – D. Gain

Gain is not a characteristic of logical families. 

Solution

Logic families indicate the types of logic circuits used in the IC. The main categories of logic families include:

• TTL (Transistor-Transistor Logic)
• CMOS (Complementary MOS)
• ECL (Emitter Coupled Logic)

Characteristics of Logic Families

The key traits of Logic families are as follows

• Speed: The amount of time that passes between applying input and changing the circuit’s output is what defines a logic circuit’s speed.
• Fan-in establishes the maximum number of inputs the logic gate can process.
• Fan-out: determines how many circuits a gate is capable of driving.
• Noise immunity: The most noise a circuit can handle without harming the output.
• Dissipation of Power: Power is lost when a circuit changes from one state to the next. 

Hence, Option (D) is the correct answer.
