Description should include
- identifying types of bipolar terminals (i.e., base, collector, and emitter)
- identifying types of terminals (i.e., field-effect, gate, source, and drain)
- describing transistor-transistor logic (TTL) and complementary metal oxide-semiconductor (CMOS) IC families
- reading a pin diagram
- correlating the markings on the chip (e.g., manufacturer code, family, subfamily, function of IC, packaging code)
- identifying types of IC packaging (e.g., round, square, rectangular)
- identifying the IC schematic symbol.
Process/Skill Questions:
- What is a pin diagram?
- Where might you find the subfamily to which the chip belongs?
- Why are there different types of IC packaging?
- How should one test the components within the chip?
