All chips in the following sections are available 5 to 10 pin surface mount packages. The right digits, after the 1G/2G/3G, typically has the same functional features as older legacy chips, except for the multifunctional chips and 4-digit chip numbers which are unique to these newer families. The "x" in the part number is a place holder for the logic family name. For example, 74x1G14 in "LVC" logic family would be "74LVC1G14". The previously stated prefixes of "SN-" and "MC-" are used to denote manufacturers, Texas Instruments and ON Semiconductor respectively.
