The single event effects and total dose radiation hardened 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. 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. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed below must be used when ordering. Detailed Electrical Specifications for the IS-139ASRH, IS-139ASEH are contained in SMD 5962-01510.
