The HS-83C55RH is a radiation hardened ROM and I/O chip 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.

The HS-83C55RH is intended for use with the HS-80C85RH radiation  
hardened microprocessor system.  
A8  
The ROM portion is designed as 16,384 mask programmable cells orga-  
nized in a 2048 word x 8-bit format. A maximum post irradiation access  
time of 340ns allows the HS-83C55RH to be used with the HS-80C85RH  
CPU without any wait states. This ROM is designed for operation utilizing  
a single 5 volt power supply.
