Answer Notes
CMOS (Complementary Metal-Oxide-Semiconductor) and TTL (Transistor-Transistor Logic) are two major families of digital integrated circuits. The standout advantage of CMOS over TTL is its extremely low power consumption.
CMOS circuits use complementary pairs of MOSFETs. Because one transistor in the pair is always off during a static state, almost no current flows except during the brief moment the logic state switches. This makes CMOS ideal for battery-powered devices.
In contrast, TTL logic uses bipolar junction transistors that draw a continuous baseline current even when not switching. While CMOS is great for low power, it is not inherently designed for high power handling, RF amplification, or power supply regulation, making those distractors incorrect.
