CMOS logic families are associated with:

1. Low power dissipation

2. High noise immunity

3. Low Fan-out

4. Comparatively high logic voltage swing 

Complementary Metal-oxide-semiconductor (CMOS) uses complementary & symmetrical pair of P-type & N-type MOSFETS.

1. The two important characteristics of CMOS devices are high noise immunity and low power dissipation.

2. In CMOS, during static operation at a time, only one MOS is ON i.e. either PMOS or NMOS. So there is no direct path from the power supply to the ground. Hence, Power dissipation in CMOS is low in static operation but it has high power dissipation in dynamic operation.

3. Fanout of CMOS is high. 

4. The gate has an almost ideal voltage-transfer characteristic. The logic swing is equal to the supply voltage and is not a function of the transistor sizes. The noise margins of asymmetrical inverter (where PMOS and NMOS transistors have equal current driving strength) approach VDD/2. The steady-state response is not affected by fanout.
