DESCRIPTION
The Mii
66342
optically coupled isolator consists of four 850 nm GaAlAs LEDs and four silicon phototransistors mounted and
coupled in a 16 pin dual-in-line package. Test studies have shown this LED to be even more radiation tolerant than the 660
nm LED typically used in radiation tolerant applications. Each unit contains four channels. These solid state couplers are
ideal for designs where board space and device weight are important design considerations.
