TheĬhart shows the speed-power relationship of common TTL families.ĭigital IC manufacturers are continually trying to minimize the delay-power product and continue to produceįamilies with different characteristics to suit specific needs. Families can be characterized by the relationship between propagation-delay and power. These two tend to be directly related, i.e., higher speedĬonsumes more power. Of each logic family are speed and power consumption. Two important factors in the consideration Many second-generation families, each with different operating characteristics. Technology which exhibits low power and high noise immunity. Another common structure is CMOS ( complementary metal-oxide-silicon) A common structure is the bipolar transistor/transitor logic (TTL) which you willīe using in the laboratory. Problem 10 - Open-collector and tri-stateĭigital logic is implemented using integrated circuits which are classified into families based on their basicĮlectronic structure.Objectives: To present basic characteristic and limitations of gates. 4D6 Lab Manual - Chapter 6 Chapter 6 Gate Characteristics
