The Intersil 5962-9456201M2A is a radiation-hardened static RAM device fabricated using silicon-on-sapphire (SOS) CMOS technology. It provides an 8K x 8 memory organization with fully asynchronous operation. The component is designed for high reliability in harsh environments, offering exceptional hardness against neutron fluence, total ionizing dose, and cosmic rays. It features low standby power consumption achieved through a gated input buffer design without pull-up resistors. The device is qualified per MIL-PRF-38535 requirements and electrically screened to SMD specification 5962-95823. It operates within a specified temperature range suitable for military and aerospace applications.
This part number belongs to the HS-65647RH family of radiation-hardened static RAMs produced by Intersil. These devices are specifically engineered for space defense and other critical applications where standard CMOS components would fail due to radiation exposure. The 5962 prefix indicates it is a Military Standard (Mil-Spec) part managed by the Defense Supply Center Columbus.
Direct replacements must match the radiation hardness specifications and the 8K x 8 organization. Verify that any substitute component meets the same MIL-PRF-38535 qualification level and has compatible pinout and electrical characteristics as defined in SMD 5962-95823.
