The HS-303CEH is an analog switch and a monolithic device that is fabricated using the Renesas dielectrically isolated Radiation Hardened Silicon Gate (RSG) process technology to ensure latch-up free operation. The HS-303CEH is pinout compatible and functionally equivalent to the HS-303RH. The HS-303CEH offers low-resistance switching performance for analog voltages up to the supply rails. ON-resistance is low and stays reasonably constant across 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 ±15V rails. Specifications See SMD 5962-95813 for detailed electrical specifications.
