ESCRIPTION
:
Maxwell Technologies’ 81840 high-performance 128-channel
multiplexer features a typical 300 krad (Si) total dose tolerance.
This datasheet defines the design, performance, and test require-
ments for a hermetic, telemetry multiplexer, multi-chip-module
(MCM), utilizing chip and wire technology to be used in space
systems. The 81840 is intended for use in the environments
encountered by high reliability spacecraft applications. The pat-
ented radiation-hardened R
AD
-P
AK
® technology incorporates radi-
ation shielding in the microcircuit package. Capable of surviving
in-space environment, the 81840 is ideal for satellite, spacecraft,
and space probe missions. It is available up to Class K screening.
