Learners follow steps to trace logic signals from the inputs of several interconnecting logic gates to one output.

In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.

Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

Learners view the operation of the 7485 integrated circuit magnitude comparator in this animated object. A quiz completes the activity.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.
