Radiation Hardened CMOS Static Clock
Controller/Generator
The Intersil HS-82C85RH is a high performance, radiation
hardened CMOS Clock Controller/Generator designed to
support systems utilizing radiation hardened static CMOS
microprocessors such as the HS-80C86RH. The
HS-82C85RH contains a crystal controlled oscillator, reset
pulse conditioning, halt/restart logic, and divide-by-256
circuitry. These features provide the means to stop the
system clock, stop the clock oscillator, or run the system at a
low frequency (CLK/256), enhancing control of static system
power dissipation and allowing system shut-down during
periods of external stress.
Static CMOS circuit design insures low operating power and
permits operation with an external frequency source from
DC to 15MHz. Crystal controlled operation to 15MHz is
guaranteed with the use of a parallel, fundamental mode
crystal and two small load capacitors. Outputs are
guaranteed compatible with both CMOS and TTL
specifications. The Intersil hardened field CMOS process
results in performance equal to or greater than existing
radiation resistant products at a fraction of the power.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-95820. A “hot-link” is provided
on our homepage for downloading.
