ISL7119RH, ISL7119EH

Radiation Hardened High Speed Dual Voltage Comparators

DATASHEET

The ISL7119RH, ISL7119EH are radiation hardened, high

speed, dual voltage comparators fabricated on a single

monolithic chip. They are 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, ISL7119EH are fabricated on our dielectrically

isolated Radiation Hardened Silicon Gate (RSG) process, which

provides immunity to Single Event Latch-Up (SEL) and highly

reliable performance in the natural space environment.
