Answer to Question #56005 in Physics for irebami

Question

The main advantage of CMOS digital ICs over TTL is found in their _________
Low power consumption
Cheaper price rate
Availability in the market
Compatibility with several boards

Answer 1

The major advantage of CMOS over TTL is that CMOS has almost no static current.
Since CMOS only draws power during a transition, low-power devices - such as wristwatches - typically use CMOS at low transition rates (lower losses).
Even devices that run at very high speeds often have lower power consumption with CMOS than other digital logic families, because typically only a few gates make a transition at a time - the vast majority of gates that don't transition save more than enough energy to make up for the few gates that transition and briefly consume more energy than TTL gates.
Answer: Low power consumption.
