HS-82C54RH Data Sheet 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.

Sep 15, 2015 CMOS Programmable Interval Timer
The Intersil 82C54 is a high performance CMOS
Programmable Interval Timer manufactured using an
advanced 2 micron CMOS process.
The 82C54 has three independently programmable and
functional 16-bit counters, each capable of handling clock
input frequencies of up to 8MHz (82C54) or 10MHz
(82C54-10) or 12MHz (82C54-12).
The high speed and industry standard configuration of the
82C54 make it compatible with the Intersil 80C86, 80C88,
and 80C286 CMOS microprocessors along with many
other industry standard processors. Six programmable
timer modes allow the 82C54 to be used as an event
counter, elapsed time indicator, programmable one-shot,
and many other applications. Static CMOS circuit design
insures low power operation.
The Intersil advanced CMOS process results in a significant
reduction in power with performance equal to or greater than
existing equivalent products. Features 8MHz to 12MHz Clock Input Frequency Compatible with NMOS 8254
