HS-82C85RH

The Intersil HS-82C85RH is a high performance, radiation hardened CMOS Clock Controller/Generator designed to support systems utilizing radiationhardened 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.
