The single event effects and total dose radiation hardened
Features
IS-139ASRH, IS-139ASEH consist 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 inputs.
• Electrically Screened to SMD # 5962-01510
• QML Qualified per MIL-PRF-38535 Requirements
• Radiation Hardness

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.
