Proton Radiation Tolerant, Quad Channel, Hermetic 20 Pin LCC, Optically Coupled Isolator

66171-103
The 66171 is an optically coupled isolator, consisting of four Red 660nm LEDs and four silicon phototransistors mounted and coupled in a miniature surface mount hermetic leadless chip carrier. The 66171 uses an LED proven to be more tolerant to proton radiation. All electrical characteristics of each channel are similar to the JEDEC registered 4N49. Each unit contains four channels. These solid state couplers are ideal for designs where board space, device weight and radiation tolerance are important design considerations.
