Electrical and Electronic Technology II

This page compiles key materials for Electrical and Electronic Technology II, along with exam preparation tips for quick reference.

Exam Tips

TTL Tri-State Gates (Likely Exam Topic)

The following points must be mastered:

1. Three states: High level, low level, and high-impedance state
2. Input characteristics: TTL inputs allow floating (treated as high level / 1)
3. Internal structure: TTL uses bipolar transistors internally, as opposed to CMOS which uses field-effect transistors (FETs)
4. Unused input handling: Refer to textbook P248

Additional Notes

• Content with triangle symbols may also be tested; foundational knowledge should still be reviewed
• Open-collector gates (OC gates): Not tested
