Briefly, TTL uses more power than more modern families.
Power dissipation.
The term used to describe how much heat a circuit dissipates is "power dissipation." It refers to the amount of power that is converted into heat as the circuit operates, usually measured in watts.
Logic families refer to groups of digital logic circuits that share similar characteristics, such as voltage levels, power consumption, and speed. Common logic families include TTL (Transistor-Transistor Logic), CMOS (Complementary Metal-Oxide-Semiconductor), and ECL (Emitter-Coupled Logic), each offering trade-offs between speed, power efficiency, and complexity. TTL is known for its robustness and moderate speed, CMOS boasts low power consumption and high density, while ECL provides the fastest switching speeds at the cost of higher power use. The choice of logic family depends on the specific requirements of an application, such as speed, power consumption, and integration density.
A figure of merit correlated with the energyefficiency of a device. It can be calculated by the product of propagation delay time with power dissipation.

Solution: Characteristics of CMOS logic: 1. Dissipates low power: The power dissipation is dependent on the power supply voltage, frequency, output load, and input rise time. At 1 MHz and 50 pF load, the power dissipation is typically 10 nW per gate. 2. Short propagation delays: Depending on the power supply, the propagation delays are usually around 25 nS to 50 nS. 3. Rise and fall times are controlled: The rise and falls are usually ramps instead of step functions, and they are 20 - 40% longer than the propagation delays. 4. Noise immunity approaches 50% or 45% of the full logic swing. 5. Logic levels in a CMOS system will be essentially equal to the power supplies since the input impedance is so high.Characteristics of TTL logic: 1. Power dissipation is usually 10 mW per gate. 2. Propagation delays are 10 nS when driving a 15 pF/400 ohm load. 3. Logic levels vary from 0 to 5 voltsSolution: Characteristics of CMOS logic: 1.

Saturated and unsaturated logic families refer to the operating states of transistors in digital circuits. In a saturated logic family, transistors are driven into saturation during the "on" state, allowing for faster switching and lower output impedance, which can improve performance but may increase power consumption. In contrast, unsaturated logic families operate in the active region, where transistors are not fully saturated, leading to higher output impedance and slower switching speeds, but typically lower power consumption. Each type has its trade-offs, affecting the design choices in integrated circuits.
It develops the power to apply logic and logic in an integral part of mathematics.
