ESCRIPTION
:
Maxwell Technologies 139 consisting of four independent pre-
cision voltage comparators, features a greater than 100 krad
(Si) total dose tolerance, depending upon space mission.
Using Maxwell Technologies radiation- hardened Rad-Pak
packaging technology, the 139 has an offset voltage specifica-
tion as low as 2 mV max for all four comparators. The 139
was also designed specifically to operate from a single power
supply over a wide range of voltages. Operation from split
power supplies is possible and the low power supply current
drain is independent of the magnitude of the power supply
voltage. These comparators also have a unique characteristic
in that the input common-mode voltage range includes
ground, even though operated from a single power supply
voltage.
Maxwell Technologies' patented R
AD
-P
AK
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 space
mission. In a GEO orbit, R
AD
-P
AK
provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.

1. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the com-
mon-mode range, the comparator will provide a proper output state. The low output voltage state must not be less than -0.3

2. Short Circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to

upper end of the common-mode voltage range is V+-1.5V at 25C, but either or both inputs can go to +30V without damage,
