HS-82C54RH

The Intersil HS-82C54RH is a high performance, radiation hardened CMOS version of the industry standard 8254 and is manufactured using a hardened field, self-aligned silicon gate CMOS process. It has three independently programmable and functional 16-bit counters, each capable of handling clock input frequencies of up to 5MHz. Six programmable timer modes allow the HS-82C54RH to be used as an event counter, elapsed time indicator, a programmable one-shot, or for any other timing application. The high performance, radiation  hardness, and industry standard configuration of the HS-82C54RH make it compatible with the HS-80C86RH radiation hardened microprocessor.

Static CMOS circuit design insures low operating power. The Intersil hardened field CMOS process results in performance equal to or greater than existing radiation resistant products at a fraction of the power.
