Single Event Radiation Hardened Quad Voltage

Comparators

IS-139ASRH, IS-139ASEH

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.
