Voltage and current measurement of TTL gates using KL-22001 basic electrical/electronic circuit lab and KL-26001 combinational logic circuit experiment module

The experiment carried out on voltage and current measurement on TTL logic gates, by the students of electrical and information engineering in the final year of their studies, in the department's laboratory, which help to understand the voltage and current characteristics of TTL gates and how also how to measure the voltage and current values of TTL gates. This experiment basically shows how voltage and current of TTL gate can be measured. KL-22001 Basic Electrical/Electronic Circuit lab and KL-26001 Combinational Logic Circuit experiment module are the major equipment used to perform the experiment. These were used because it is much more self-explanatory and easier to work with compared other models. It was discovered that Due to its higher resistance value the LS series, TTL gates have lower input current than the standard series TTL gates. Their output currents are about equal.
