HS-139RH-T

Radiation Hardened Quad Voltage

Comparator

tested and guaranteed to 100kRAD total dose. These QML

Class T devices are processed to a standard flow intended

to meet the cost and shorter lead-time needs of large

volume satellite manufacturers, while maintaining a high

level of reliability.

The Radiation Hardened HS-139RH-T 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 make these comparators

suitable for low power applications. These types were

designed to directly interface with TTL and CMOS.

The HS-139RH-T is 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

Specifications for Rad Hard QML devices are controlled by
