DESCRIPTION
The Mii 66143 -002, -003 and -004 are optically coupled isolators, consisting of four GaAlAs LEDs and four silicon
phototransistors mounted and coupled in a miniature surface mount hermetic leadless chip carrier. All electrical
characteristics of each channel are identical to the JEDEC registered 4N47 (-002), 4N48 (-003) and 4N49 (-004). Each unit
contains four channels. These solid state couplers are ideal for designs where board space and device weight are important
design considerations.
