Rad-Hard Analog Switch

The HS-303CEH is an analog switch and a monolithic device that is fabricated using Intersil’s dielectrically isolated Radiation Hardened Silicon Gate (RSG) process technology to insure latch-up free operation. It is pinout compatible and functionally equivalent to the HS-303RH. This switch 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-303CEH can operate with rails of ±15V.
