Digital Integrated Circuits

I.     Course Prefix/Number: ELT 225

       Course Name: Digital Integrated Circuits

       Credits: 3 (2 lecture; 2 lab)

II.    Prerequisite

ELT 221

III.   Course (Catalog) Description

Hands-on course covers applications of digital integrated circuits. Content includes use of gates, registers, drivers, memory circuits and various circuits that are available as “chips” I.C.s are presented. Course involves lecture and lab experiments, and use of the applications manual.

IV.   Learning Objectives

Student will learn to:

  1. Define and demonstrate the functions of digital integrated circuits for both the CMOS and TTL families.
  2. Describe the application of CMOS and TTL digital integrated circuits
  3. Design and test various application of CMOS and TTL circuits using logic gates.
  4. Analyze circuits using computer simulation software.
  5. Communicate effectively in a technical and non-technical environment
  6. Compile and prepare laboratory reports.
  7. Analyze and troubleshoot digital integrated circuit problems.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

VI.   Sequence of Topics

  1. Binary operations
  2. Logic gates and their symbols
  3. Boolean algebra
  4. Logic and state transitions
  5. Sequential logic
  6. Basic computer organization and register transfer logic
  7. I/O implementations
  8. Microprocessor and microcontroller programming
  9. Computer logic design

VII.  Methods of Instruction

The course will be divided, one half lecture and one half lab.  There will be a heavy concentration on the practical use of these devices.  As a result there will be many construction projects using proto boards and implementing practical circuit approaches.

Course may be taught as face-to-face, hybrid or online course.

VIII. Course Practices Required

  1. Attendance of lectures and lab sessions.
  2. Completing homework and lab assignments.
  3. Building of an AM radio receiver.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

Textbook:  Modern Electronic Communication by Gary M. Miller, 3rd Edition
Lab book and components will be provided.
Project:  Build and test an AM radio.  Student will purchase the AM kit.

X.    Methods of Evaluating Student Progress

Four to five one hour exams 70%
Lab assignments 20%
Homework assignments 10%
A:  90 - 100
B: 80 - 89
C: 70 - 79
D: 60 - 69
F: Below 60

XI.   Other Course Information

Attendance and participation is recommended.  No late assignments will be accepted.  The homework is due on the following session.  A make-up test may be given on the following session if the student had a good excuse (working, out-of-town, sick, etc.).  If the student missed the make-up test too, then he will be awarded the lowest grade of the semester tests, whichever is lower.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.

Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.
