The HS-302AEH is a dual Double-Pole, Single-Throw (DPST) analog switch fabricated using Intersil’s dielectrically isolated Radiation Hardened Silicon Gate (RSG) process technology to ensure latch-up free operation. It is pin compatible and functionally equivalent to the HS-302RH.

This switch 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 over the full range of operating voltage and current as well 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.

Key Features

• Electrically screened to DLA SMD# 5962-95812
• No latch-up, dielectrically isolated device islands
• Pin and functionally compatible with Intersil HS-302RH series analog switches
• Analog signal range equal to the supply voltage range
• Low leakage: 150nA (maximum, post-rad)
• Low rON: 60Ω (maximum, post-rad)
• Low standby supply current . . ±150μA (maximum, post-rad)
• Radiation assurance
  • High dose rate (50 to 300rad(Si)/s): 100krad(Si)
  • Low dose rate (0.01rad(Si)/s): 50krad(Si)*
• Single event effects
  • For LET = 60MeV•mg/cm2 at 60° incident angle, <150pC charge transferred to the output of an off switch* Product capability established by initial characterization. The EH version is acceptance tested on a wafer-by-wafer basis to 50krad(Si) at low dose rate.
