It has excellent noise immunity amongst all families. Of the above mentioned families DL, RTL and DTL are not used these days they have become obsolete.

Now the Bi-MOS logic family is the one that uses both bipolar and MOS devices. Characteristics of CMOS Logic Families. TTL, CMOS, ECL, NMOS and Bi-CMOS are the families which are still used.

Complementary metal–oxide–semiconductor (CMOS), also known as complementary-symmetry metal–oxide–semiconductor (COS-MOS), is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. The members of other logic family i.e. CMOS technology is used for constructing integrated circuit (IC) …

MOS family are PMOS, NMOS family, CMOS family. The 4000A CMOS family has been replaced by its high-voltage versions in the 4000B and 4000UB CMOS families, with the former having buffered and the latter having unbuffered outputs. CMOS supports a very large fan-out, more than 50 transistors.

54/74C, 54/74HC, 54/74HCT, 54/74AC and 54/74ACT are CMOS logic families with pin-compatible 54/74 TTL series logic functions.

The propagation delay is the worst when compared with TTL and ECL families at about 200ns. A logic low voltage for CMOS is about; A logic high voltage for ECL is somewhere between 4.5V to 5V.
