A)Find the DC noise margin for the TTL-LS 74LS** or 54 LS ** logic family using the data sheet provided (Blackboard)or a similar one that you find on-line. Circle the voltage values that you used on the data sheet. b) Calculate the Fan-Out for this circuit. Circle the current value that you used on the data sheet.

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction
