TTL

74 - the "standard TTL" logic family had no letters between the "74" and the specific part number.
74L - Low power (compared to the original TTL logic family), very slow
H - High speed (still produced but generally superseded by the S-series, used in 1970s era computers)
S - Schottky (obsolete)
LS - Low Power Schottky
AS - Advanced Schottky
ALS - Advanced Low Power Schottky
F - Fast (faster than normal Schottky, similar to AS)
