Rev 4.00
April 6, 2012 Single Event Radiation Hardened Quad Voltage Comparators
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. Features Electrically Screened to SMD # 5962-01510 QML Qualified per MIL-PRF-38535 Requirements Radiation Hardness
