Is this brief enough?

7400		Original TTL
74F00		I dunno
74ALS00		Advanced Low-Power Schottky, improved noise immunity over LS
74AS00		Advanced Schottky
74C00		CMOS
74HC00		High-Speed CMOS, 'LS' Comparable speed
74HCT00		High-Speed CMOS, TTL Voltage Compatible
74H00		High-Speed TTL
74L00		Low-Power TTL
74S00		Schottky
74LS00		Low-Power Schottky

Anyone have a rule of thumb for compatible types, incompatible types?
