ESCRIPTION
:
Maxwell Technologies’ 306 high-performance, high-precision,
monolithic, CMOS analog multiplexer features a greater than
50 krad (Si) total dose tolerance, depending upon space mis-
sion. The patented radiation-hardened R
AD
-P
AK®
technology
incorporates radiation shielding in the microcircuit package.
Using Maxwell’s radiation hardened R
AD
-P
AK
packaging tech-
nology, this single-ended 1-of-16 device offers very low (less
than 100
Ω
) on-resistance which is matched to within 5
Ω
between channels and remains flat over the specified analog
signal range. The 306 also offers low leakage over tempera-
ture and fast switching speeds. The 306 operates with a single
+4.5V to +30V supply, or bipolar ±4.5V to ± 20V supplies,
while retaining TTL/CMOS- logic input compatibility and fast
switching.
Maxwell Technologies' patented Rad-Pak packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or a space
mission.In a GEO orbit, Rad-Pak provides greater than 50
krad (Si) total radiation dose tolerance, dependent upon space
mission. This product is available with packaging and screen-
ing up to Class S.
