81C55 Datasheet (Intersil Corporation) - Radiation Hardened 256 x 8 CMOS RAM

81C55, Radiation Hardened 256 x 8 CMOS RAM

The HS-81C55/56RH are radiation hardened RAM and I/O chips fabricated using the Intersil radiation hardened SelfAligned Junction Isolated (SAJI) silicon gate technology.

Latch-up free operation is achieved by the use of epitaxial starting material to eliminate the parasitic SCR effect seen in conven
