connecting two totem pole outputs together

In order to put into perspective where the above devices fit into the scheme of things and how far we have come, Sub-families with their characteristics and designations The following table is a growing list of various 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. As a result, output line 7 is driven LOW.4D6 Lab Manual - Chapter 6 Chapter 6 Gate Characteristics The input at the 1, 2, 4, 8 inputs to a 4-line to 16-line decoder with active- low outputs is 1110.How many outputs would two 8-line-to-3-line encoders, expanded to a 16-line-to-4-line encoder, have?.Which output goes LOW when the inputs are 1001?

A certain BCD-to-decimal decoder has active-HIGH inputs and active- LOW outputs.For the device shown here, assume the D input is LOW, both S inputs are HIGH, and the input is HIGH.Which of the following logic gives the complementary outputs?.

MULTIPLEXER, ARE CONNECTED TOGETHER THROUGH A 4-INPUT

THE FOUR OUTPUTS OF TWO 4-INPUT MULTIPLEXERS, CONNECTED TO FORM A 16-INPUT.

A TTL totem-pole circuit is designed so that the output transistors:.

A standard TTL circuit with a totem-pole output can sink, in the LOW state (IOL(max)),.
