81C55中文资料INTERSIL数据手册PDF规格书

The HS-81C55/56RH are radiation hardened RAM and I/O chips fabricated using the Intersil radiation hardened Self Aligned 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 conventional bulk CMOS devices.
