Thanks @YOGI.

CMOS is the advanced version of TTL. So it consumes less power than TTL.

Because ttl logic is replaced by cmos logic to reduce the power.

I'm not sure about how much volt it ll consume but its definetly less than that of TTL opponent because CMOS circuits are less likely to produce power supply transients when switching between states. The transition level between high and low logic states is usually half the supply voltage, which means CMOS has superior noise immunity to TTL.

How much supply voltage?
