Power Dissipation
Logic Gates and Logic circuits consume varying amount of power during their operation.
Ideally, logic gates and logic circuit should consume minimal power. Advantages of low power consumption are circuits that can be run from batteries instead of mains power supplies. Thus portable devices that run on batteries use Integrated circuits that have low power dissipation. Secondly, low power consumption means less heat is dissipated by the logic devices; this means that logic gates can be tightly packed to reduce the circuit size without having to worry about dissipating the access heat generated by the logic devices.
Microprocessors for example generate considerable heat which has to be dissipated by mounting small fans. Generally, the Power dissipation of TTL devices remains constant throughout their operation. CMOS device on the other hand dissipate varying amount power depending upon the frequency of operation.
