Maxwell Technologies 139 consisting of four independent precision 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 specification 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 RAD-PAK packaging technology incorporates radiation shielding in the microcircuit package. 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, RAD-PAK 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 common-mode range, the comparator will provide a proper output state. The low output voltage state must not be less than -0.3
VDC (or 0.3 VDC below the magnitude of the negative power supply, if used) (at 25°C).
2. Short Circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to
ground, the maximum output current is ~20mA independent of the magnitude of V+.
3. 1.5 kΩ in series with 100 pF.

1. At output switch point, VO=1.4V, RS=0Ω with V+ from 5VDC to 30 VDC; and over the full input common-mode range (0VDC to
V+-1.5VDC).
2. The direction of the input current is out of the IC due to the PNP input stage. This current essentially constant, independent of
the state of the output so no loading change exists on the reference or input lines.
3. The input common-mode voltage or either input voltage signal should not be allowed to go negative by more than 0.3V. The
upper end of the common-mode voltage range is V+-1.5V at 25°C, but either or both inputs can go to +30V without damage,
independent of the magnitude of V+.
4. The response time specified is for a 100mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be
obtained.
5. Positive excursions of input voltage may exceed the power level as long as the other voltage remains within the common
mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3 VDC (or
0.3VDC below the magnitude of the negative power supply, if used) (at 25°C).
