HS-303BRH

Description

The HS-303ARH and HS-303BRH analog switches are monolithic devices fabricated using Intersils dielectrically isolated Radiation Hardened Silicon Gate (RSG) process technology to insure latch-up free operation. They are pinout compatible and functionally equivalent to the HS-303RH, but offer improved 300kRAD(Si) total dose capability. These switches offers low-resistance switching performance for analog voltages up to the supply rails. ON resistance is low and stays reasonably constant over the full range of operating voltage and current. ON resistance also stays reasonably constant when exposed to radiation. Break-before-make switching is controlled by 5V digital inputs. The HS-303ARH should be operated with nominal 15V supplies, while the HS-303BRH should be operated with nominal 12V supplies. Specifications Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed below must be used when ordering. Detailed Electrical Specifications for the HS-303ARH and HS-303BRH are contained in SMD 5962-95813. A hot-link is provided from our website for downloading.
