Radiation Hardened BiCMOS Dual SPDT Analog Switch

HS-303CEH

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.

Specifications

The Detailed Electrical Specifications for the HS-303CEH is

contained in SMD 5962-95813. A “hot-link” is provided from
