8. A CD4011 gate package is operating from an 8 volt power VDD supply. What should the values VOH, VOL, VIH, and VOL be for each gate in this IC package? 9. Repeat Problem 8 for VDD=12 V. 10. What is "latch up" in an integrated circuit and what is the most common cause of this condition? (Cite your source of information when answering this question.) 11. One of the NOT gates in a CD4049 package is to be used to drive multiple 7404 gate inputs. The CD4049 is operating from VDD=5V, and the 7404 gates are operating from Vcc=5V. a) Are these two families compatible as interfaced? (Cite the four voltage specifications from the data sheets a simple yes or no answer is insufficient.) b) What is the DC fan-out? 12. A CD4011 NAND gate is operating from 3.3 V and one of its inputs is driven from a 74HC04 NOT gate operating from 5 V. What might happen with this particular interconnection and how could you prevent this from happening?
