Data Sheet
August 2000
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.

• Pin Compatible with NMOS 8254 and the Intersil 82C54
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.
