DESCRIPTION
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 RAM portion is designed as 2048 static cells organized as 256 x 8. A maximum post irradiation access time of 500ns allows the HS-81C55/56RH to be used with the HS-80C85RH CPU without any wait states. The HS-81C55RH requires an active low chip enable while the HS-81C56RH requires an active high chip enable. These chips are designed for operation utilizing a single 5V power supply.FEATURES
