Voltage Comparator The ISL7119RH is a radiation hardened high speed dual voltage comparator fabricated on a single monolithic chip. It is designed to operate over a wide dual supply voltage range as well as a single 5V logic supply and ground. The open collector output stage facilitates interfacing with a variety of logic devices and has the ability to drive relays and lamps at output currents up to 25mA. The ISL7119RH is fabricated on our dielectrically isolated Rad-hard Silicon Gate (RSG) process, which provides immunity to Single Event Latch-up (SEL) and highly reliable performance in the natural space environment. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed below must be used when ordering. Detailed Electrical Specifications for the ISL7119RH are contained in SMD 5962-07215. A “hot-link” is provided on our website for downloading.
