Single Event Radiation Hardened Quad Voltage
Comparators
IS-139ASRH, IS-139ASEH
Features
• Electrically Screened to SMD # 5962-01510
The single event effects and total
dose radiation hardened IS-139ASRH,
IS-139ASEH consist of four
independent single or dual supply
• QML Qualified per MIL-PRF-38535 Requirements
TM
• Radiation Hardness
- Total Dose . . . . . . . . . . . . . . . . . . . . . . . . . 300krad(Si) (Max)
voltage comparators on a single
2
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)
IO
The IS-139ASRH, IS-139ASEH are 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.
• Quiescent Supply Current . . . . . . . . . . . . . . . . . . . . 3mA (Max)
• Differential Input Voltage Range Equal to the Supply Voltage
Applications
• DC-DC Power Conversion
• Pulse Generators
Specifications for Rad Hard QML devices are controlled by the
