Shocked! Next sem teaching load (ATA)

I was very surprised when I saw ATA for the next sem. I have to teach ELE361, Digital electronics for electronics students. It is a major subject for electronics and I don't qualify to teach a major subject for electronics. I can teach general subject for electrical engineering,  but not the major subject for electronics and instrumentation. It is not my field. In computer engineering, I am also not qualified to teach networking subject (CISCO). Honestly, I am not interesting. I prefer digital design and microprocessor. 

The contents of ELE361 :

• Intro. to the IC technology
• Bipolar transistor as a switch 
• Logic gates characteristics and parameters
• Datasheet representation
• TTL ICs
• CMOS ICs
• TTL-CMOS interfacing
• Schmitt Trigger ICs
• Transmission line behavior

Honestly, these are not my familiar topic and I never learnt about them in details as their syllabus.  I exchanged with Siti Aishah because she is in electronics field. I take her one group of Linear subject (ESE242). Then, I exchange with Baiti to take Digital system 2 (ECE361).
