Radiation Hardened
CMOS Dual SPDT Analog Switch
The HS-303ARH and HS-303BRH analog switches are
monolithic devices fabricated using Intersil’s 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.
