The HS-139RH is a quad voltage comparator produced by Intersil Corporation. It is fabricated using the dielectrically isolated Rad Hard Silicon Gate (RSG) process, which provides an immunity to Single Event Latch-up (SEU) and the capability of highly reliable performance in any radiation environment.
The HS-139RH integrates four independent voltage comparators on a single monolithic substrate. It operates from single or dual supplies, offers a differential input range equal to the supply voltage, and features low quiescent current suitable for low‑power applications. The device is fabricated using a rad‑hard silicon gate process that provides immunity to single‑event latch‑up and reliable performance in radiation environments.
Key specifications include a 100 V output voltage withstand capability, ESD protection exceeding 3000 V, a maximum input offset of 2 mV, and a quiescent supply current of 2 mA. Ordering information, pinouts, die dimensions, and material details are provided for designers and procurement engineers.
