Which of the following is an advantage of BiCMOS logic?
The correct answer is C: It has the high input impedance of CMOS and the low output impedance of bipolar transistors. Which of the following is an advantage of BiCMOS logic is that it has the high input impedance of CMOS and the low output impedance of bipolar transistors. BiCMOS combines CMOS and bipolar advantages. For amateur radio operators, this is important for digital circuits. Understanding this helps when selecting logic families.
Exam Tip
BiCMOS advantage = high input impedance of CMOS and low output impedance of bipolar. Think 'B'iCMOS = 'B'est of 'B'oth (CMOS input, bipolar output). BiCMOS combines CMOS and bipolar advantages. Not simplicity, not ESD immunity - just high input impedance and low output impedance.
Memory Aid
"BiCMOS advantage = high input impedance of CMOS and low output impedance of bipolar. Think 'B'iCMOS = 'B'est of 'B'oth. BiCMOS combines CMOS and bipolar advantages. Important for digital circuits."
Real-World Application
BiCMOS logic: An advantage is that it has the high input impedance of CMOS and the low output impedance of bipolar transistors. This combines the best of both technologies. This is the advantage - high input impedance and low output impedance.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Simplicity resulting in less expensive devices isn't the advantage - BiCMOS has high input impedance and low output impedance. Simplicity isn't the advantage.
Option B: Incorrect. Immune to electrostatic damage isn't the advantage - BiCMOS has high input impedance and low output impedance. ESD immunity isn't the advantage.
Option D: Incorrect. Since A and B are not correct, 'all of the above' cannot be correct. Only high input impedance and low output impedance is the advantage.
