The Intersil HS-65647RH is a fully asynchronous 8K x 8 radiation hardened static RAM. This RAM is fabricated using the Intersil 1.2 micron silicon-on-sapphire CMOS technology. This technology gives exceptional hardness to all types of radiation, including neutron fluence, total ionizing dose, high intensity ionizing dose rates, and cosmic rays. Low power operation is provided by a fully static design. Low standby power can be achieved without pull-up resistors, due to the gated input buffer design. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-95823. A "hot-link" is provided on our homepage for downloading. www.intersil.com/spacedefense/space.asp
