HS-82C54RH

Radiation Hardened CMOS Programmable

Interval Timer

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.
