The Radiation Hardened HS-139RH, HS-139EH consists of four
independent single or dual supply voltage comparators on a
single monolithic substrate. The common mode input voltage
range includes ground, even when operated from a single
supply and the low supply current makes these comparators
suitable for low power applications. These types were designed
to directly interface with TTL and CMOS.
Features
• QML qualified per MIL-PRF-38535 requirements
• Radiation environment
- Latch-up free under any conditions

- SEU LET threshold . . . . . . . . . . . . . . . . . . . 20MeV/cm /mg
The HS-139RH, HS-139EH are fabricated on our dielectrically
isolated Rad Hard Silicon Gate (RSG) process, which provides
an immunity to Single Event Latch-up and the capability of
highly reliable performance in any radiation environment.
- Low dose rate effects immunity
• 100V output voltage withstand capability
• ESD protection to >3000V
