the series is the 7416xxx variant, representing mostly the 16-bit-wide counterpart of otherwise 8-bit-wide "base" chips with the same three ending digits. Thus e.g. a "7416373" would be the 16-bit-wide equivalent of a "74373". Some 7416xxx parts, however, do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, which needs making use of the 7416xxx series' higher pin count. For more details, refer primarily to the Texas Instruments documentation mentioned in the References section. For CMOS (AC, HC, etc.) subfamilies, read "open drain" for "open collector" in the table below. There are a few numeric suffixes that have multiple conflicting assignments, such as the 74453. Logic gates Since there are numerous 7400-series parts, the following groups related parts to make it easier to pick a useful part number. This section only includes combinational logic gates. For part numbers in this section, "x" is the 7400-series logic family, such as LS, ALS, HCT, AHCT, HC, AHC, LVC, ... Normal inputs / push–pull outputs {| class="wikitable" |- ! Configuration !!
