Radiation Hardened Quad Voltage Comparator
HS-139RH, HS-139EH
Features
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.
• QML qualified per MIL-PRF-38535 requirements
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.
• 100V output voltage withstand capability
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.
• Input offset voltage (VIO). . . . . . . . . . . . . . . . . . . . . 2mV (Max)
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.
