Radiation Hardened CMOS Dual SPDT Analog Switch
HS-303ARH, HS-303AEH, HS-303BRH, HS-303BEH
The HS-303ARH, HS-303AEH, HS-303BRH, HS-303BEH 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.
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,
HS-303AEH, HS-303BRH, HS-303BEH are contained in
SMD 5962-95813. A “hot-link” is provided from our website for
