Which of the following is an advantage of CMOS integrated circuits compared to TTL integrated circuits?
The correct answer is A: Low power consumption. An advantage of CMOS integrated circuits compared to TTL integrated circuits is low power consumption. CMOS uses very little power, especially when not switching, while TTL consumes more power. For amateur radio operators, this is important for battery-powered equipment. Understanding this helps when selecting logic circuits.
Exam Tip
CMOS advantage vs TTL = low power consumption. Think 'C'MOS = 'C'onsumes 'M'inimal 'O'perating 'S'upply (low power). CMOS uses very little power, especially when not switching. Not power handling, not RF amplification, not power regulation - just low power consumption.
Memory Aid
"CMOS advantage vs TTL = low power consumption. Think 'C'MOS = 'C'onsumes 'M'inimal. CMOS uses very little power, especially when not switching. Ideal for battery-powered equipment."
Real-World Application
You design a battery-powered digital circuit. CMOS logic consumes microamps when idle, while TTL consumes milliamps. This makes CMOS ideal for battery-powered equipment. CMOS's low power consumption is a major advantage over TTL for portable applications.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. CMOS doesn't have high power handling capability - CMOS is low power, not high power. Power handling isn't an advantage.
Option C: Incorrect. CMOS isn't better suited for RF amplification - CMOS is for digital logic, not RF. RF amplification isn't an advantage.
Option D: Incorrect. CMOS isn't better suited for power supply regulation - that's not a CMOS advantage. Power supply regulation isn't the advantage.
