a) One TTL gate is to be used to drive one input of each of three CMOS gates as shown. Check the voltage and current compatibility and how you will solve any sort of incompatibility? [4 Pts] b) Determine how many 74HCTMOS gates can be driven by a single 74LSTTL gate? [2 Pts.] c) Which logic family among these four has the highest propagation delay? What is the origin of this delay? [3 Pts] d) Compare between CMOS and TTL families in terms of: static charge susceptibility, power consumption, , and density of logic functions on a single chip.
