NTE3087 Optoisolator High Speed, Open Collector, NAND Gate Output Description: The NTE3087 is an optoisolator which combines a GaAsP LED as the emitter and an integrated high gain multistage high speed photodetector. The output of the detector circuit is an open collector, Schottky clamped transistor capable of sinking 50mA. The open collector output provides capability for bussing, ORing and strobing. The NTE3087 is packaged in a plastic 8pin miniDIP.
