What is the power dissipation for TTL?
power dissipation of a logic circuit is usually defined as the supply power required for the gate to operate with a 50% duty cycle at a specific frequency.
What measures the performance of a logic circuit using propagation delay and power dissipation?
Speed-Power-Product or SPP
What logic gate characteristic is the product of the DC supply voltage and the average supply current?
Power Dissipation
What is interference between ic ttl and cmos?
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.

Which logic family dissipates the minimum power?
Cmos logic family, because it has no resistors attached who consume active power.
What is the difference between power consumption and power dissipation?
