Description

The PS2841-4A and PS2841-4B are optically coupled isolators containing GaAs light emitting diodes and NPN silicon phototransistors. These products include four channels in a single package for high-density mounting applications. The PS2841-4A and PS2841-4B are the world's smallest class of photocouplers and realize about 50%reduction in mounting area compared with the PS280x and PS281x Series.
