-Replacement, Any D4364C-##L or -##LL:
-:You don't want "CX" or "G" in place of the "C"
-:The original "-20L" part was the slowest they ever made (200ns)
-:The ones you find easier now are all faster, which is fine. (-15/12/10 = 150/120/100 ns)
-:The "L" is low power. "LL" is even better, even lower power (standby memory battery lasts longer)
