Radiation Hardened CMOS Dual DPST Analog Switch
HS-302RH, HS-302EH
Intersil’s Satellite Applications Flow™ (SAF) devices are fully
tested and guaranteed to 100kRAD Total Dose. These QML
Class T devices are processed to a standard flow intended to
meet the cost and shorter lead-time needs of large volume
satellite manufacturers, while maintaining a high level of
reliability.
The HS-302RH, HS-302EH analog switches are a monolithic
device fabricated using Radiation Hardened CMOS technology
and the Intersil dielectric isolation process for latch-up free
operation. Improved total dose hardness is obtained by layout
(thin oxide tabs extending to a channel stop) and processing
(hardened gate oxide). These switches offer 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,
being typically 30Ω pre-rad and 35Ω post 100kRAD(Si). These
devices provide break-before-make switching.
Specifications
Specifications for Rad Hard QML devices are controlled by the
Defense Logistics Agency Land and Maritime (DLA). The SMD
