FN9000.2
Single Event Radiation Hardened Quad
Voltage Comparator
Features
• Electrically Screened to SMD # 5962-01510
The single event effects and total
dose radiation hardened
• QML Qualified per MIL-PRF-38535 Requirements

• Radiation Hardness
IS-139ASRH consists of four
independent single or dual supply
- Total Dose . . . . . . . . . . . . . . . . . . . . 300krad(Si) (Max)

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 inputs.
- Single Event Latch-up . . . . . . . . . . . . >84MeV/mg/cm

• Operating Supply Voltage Range. . . . . . . . . . . . 9V to 30V
• Input Offset Voltage (V ) . . . . . . . . . . . . . . . . 5mV (Max)

• Quiescent Supply Current . . . . . . . . . . . . . . . . 3mA (Max)
The IS-139ASRH is fabricated on our dielectrically isolated
Rad Hard Silicon Gate (RSG) process, which provides
immunity to single event latch-up and the capability of highly
reliable performance in any radiation environment.
• Differential Input Voltage Range Equal to the Supply
Voltage
• 100V Output Voltage Withstand Capability
