HS-303CEH Datasheet, PDF (1/10 Pages) Intersil Corporation – Radiation Hardened BiCMOS Dual SPDT Analog Switch

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
our website for downloading.
