The variable I C C H represents the dc supply current from V C C when all outputs of an 1C are HIGH. The variable I C C L represents the dc supply current when all outputs are LOW. For a 74LS00 1C, determine the typical power dissipation when all four gate outputs are HIGH. (See data sheet in Figure 3-640.)

R2 R1 RL R3 Given 1 = 4 A R1 = 72 R2 = 20 R3 = 32 For the above circuit, determine VTh and RTh to the left of the (a,b) terminals. Additionally, find RL for maximum power transfer and find that max power, Pmax, delivered to the load resistor RL. You must show all your work, including redrawing circuits as necessary. Clearly show your steps for finding VTh RTh RL, and pmax: Finally, put a box around each of your answers for VTh, RTh: RL, and pmax- Take a picture of your handwritten analysis and upload it as a single PDF or JPG for this problem. 治
Using a decoder and external gates, design the combinational circuit defined by the following three Boolean functions:1. (a) F 1 = x ′ y z ′ + x z F 2 = x y ′ z ′ + x ′ y F 3 = x ′ y ′ z ′ + x y2. (b) F 1 = ( y ′ + x ) z F 2 = y ′ z ′ + x ′ y + y z ′ F 3 = ( x + y ) z
The input of an IC requires a constant 5 V, but the supply voltage is 9 V. Use thevoltage divider equations to create a voltage divider with an output of 5 V. Assumethe IC has such a high input resistance (10 MΩ) that it practically draws nocurrent from the divider.
