DESCRIPTION:
Space Electronics’ 82C84ARP (RP for RAD-PAK®) high speed CMOS micro-
circuit features a minimum 100 kilorad (Si) total dose tolerance; depen-
dent upon orbit. Using SEi’s radiation-hardened RAD-PAK® packaging
technology, the 82C84ARP is a high performance clock generator-driver
designed to service the requirements of the Intel’s M80C86 and M8086.
Power consumption is a fraction of that of equivalent bipolar circuits. The
chip contains a crystal controlled oscillator, a divide-by-three counter and
complete READY synchronization and reset logic. Crystal controlled oper-
ation up to 15, 25 MHz utilizes a parallel, fundamental mode crystal and
two small load capacitors. Capable of surviving space environments, the
82C84ARP is ideal for satellite, spacecraft, and space probe missions. SEi’s
RAD-PAK® incorporates radiation shielding in the microcircuit package. It
eliminates box shielding while providing required lifetime in orbit. This
product is available with packaging and screening up to Class S.
