HM2510 RAM 1K Hitachi Static 1024x1 RAM Fast IC MIL Hermetic 1976 Rare Collectible

These rare, collectible, working, nostalgia items are genuine Hitachi Semiconductor made, early, fast Static 1K RAM (Random Access Memory) organized as 1024x1 units in unused condition. Although they are not the first memory IC (Integrated Circuit) made, but they are early static TTL (Transistor Transistor Logic) RAM parts as shown by the 1976 date/factory code. Not very many of the two different types available.

These full Military tempearture range, radiation hardened ICs are made in a white ceramic sidebraced 16 pin DIL (dual-inline) package with gold plated case and leads. They are excellent when speed is important - not many parts faster than bipolar static RAMs, for a longevity study, experimentation, special circuit design or for factory new replacement parts for vintage equipment restoration. These are real hard to find collector's choice semiconductors.
