General Description

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 conventional bulk CMOS devices.

The HS-81C55/56RH is intended for use with the HS-80C85RH radiation hardened microprocessor system.
