DESCRIPTION:

•

Rad-Pak® technology-hardened against natural space

radiation

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.

Total dose hardness:

- >100 krad (Si), depending upon orbit and space mission

Single Event Effects:

- SEL > 59.8 MeV/mg/cm²

•

Package:

- 14 pin Rad-Pak® flat package

Wide supply voltage range

- 2 VDC to 36 VDC or ±1 VDC to ±18 VDC

Very low supply current drain:

•

- (0.8 mA) - independent of supply voltage

Low input biasing current: 25 nA

Differential input voltage range equal to the power supply

voltage

•

Low output saturation voltage: 250 mV at 4 mA

Power drain suitable for battery operation

Allows sensing near GND

Maxwell Technologies' patented R^AD-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 space

mission. In a GEO orbit, R^AD-PAK provides greater than 100

krad (Si) radiation dose tolerance. This product is available

with screening up to Class S.

Eliminates need for dual supplies

Output voltage compatible with TTL, DTL, ECL, MOS and

CMOS logic systems

•

Low input offset current and offset voltage:

- +5 nA, +3 mV
