Description should include the operational similarities and differences of the 7400 and 4000 families of logic gates. It should also include
- bipolar junction transistors (BJT) vs. field effect transistors (FET)
- voltage requirements
- prefix (usually 74 or 40)
- metal-oxide-semiconductor (MOS) chips compared to TTL chips.
Process/Skill Questions:
- What is the prefix for a TTL family chip?
- What is the prefix for a MOS family chip?
- Which family is more prone to damage by static electricity?
- Which chip functions better in higher voltage?
- Which chip functions better in lower voltage (5V or less)?
