HS-303RH-T
Radiation Hardened
CMOS Dual SPDT Analog Switch
Intersil’s Satellite Applications FlowTM (SAF) devices are fully
tested and guaranteed to 100kRAD total dose. These QML
Class T devices are processed to a standard ow intended
to meet the cost and shorter lead-time needs of large
volume satellite manufacturers, while maintaining a high
level of reliability.
The HS-303RH-T analog switch is 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). 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, being typically 30 pre-rad and 35
post 100kRAD(Si). Break-before-make switching is
controlled by 5V digital inputs.
Specications
Specications for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed electrical specications for the HS-303RH-T are
contained in SMD 5962-95813. A “hot-link” is provided from
our website for downloading.
Intersil’s Quality Management Plan (QM Plan), listing all
Class T screening operations, is available on our website.
