DATASHEET
Radiation Hardened CMOS Dual DPST Analog Switch
HS-302AEH
Features
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
insure latch-up free operation. It is pin compatible and
functionally equivalent to the HS-302RH.
• 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
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.

• Low standby supply current . . ±150µA (maximum, post-rad)
• Radiation assurance
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.
