NTE NTE3087 Datasheet
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 multi–stage 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 8–pin mini–DIP.
