The HS-303ARH and HS-303BRH analog switches aremonolithic devices fabricated using Intersil’s dielectricallyisolated Radiation Hardened Silicon Gate (RSG) processtechnology to insure latch-up free operation. They are pinoutcompatible and functionally equivalent to the HS-303RH, butoffer improved 300kRAD(Si) total dose capability. Theseswitches offers low-resistance switching performance foranalog voltages up to the supply rails. “ON” resistance is lowand stays reasonably constant over the full range ofoperating voltage and current. “ON” resistance also staysreasonably constant when exposed to radiation.Break-before-make switching is controlled by 5V digitalinputs. The HS-303ARH should be operated with nominal±15V supplies, while the HS-303BRH should be operatedwith nominal ±12V supplies.SpecificationsSpecifications for Rad Hard QML devices are controlled bythe Defense Supply Center in Columbus (DSCC).
