The single event effects and total dose radiation hardened IS-139ASRH 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 inputs.
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.
Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed below must be used when ordering.
Detailed Electrical Specifications for the IS-139ASRH are contained in SMD 5962-01510. A "hot-link" is provided on the Intersil website for downloading.
