HS-139RH, HS-139EH

Radiation Hardened Quad Voltage Comparator

DATASHEET

The Radiation Hardened HS-139RH, HS-139EH 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.

The HS-139RH, HS-139EH are fabricated on our dielectrically

isolated Rad Hard Silicon Gate (RSG) process, which provides

an 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 HS-139RH, HS-139EH

are contained in SMD 5962-98613. A “hot-link” is provided on

our homepage with instructions for downloading.
