The HS-302AEH is a dual Double-Pole, Single-Throw (DPST) analog switch fabricated using the Renesas dielectrically isolated Radiation Hardened Silicon Gate (RSG) process technology to ensure latch-up free operation. The HS-302AEH is pin compatible and functionally equivalent to the HS-302RH. The HS-302AEH offers convenient switching controlled by 5V digital inputs and 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 and as over exposure to radiation. The HS-302AEH is available in a 14 Ld CDFP or die form and operates across the extended temperature range of -55°C to +125°C.
