NTE NTE3090 Datasheet
NTE3090
Optoisolator
Schmitt Trigger Output
Description:
The NTE3090 is an optoisolator in a 6–Lead DIP type package and contains a gallium arsenide IRED
optically coupled to a high–speed integrated detector with a Schmitt Trigger output. This device is
designed for applications requiring electrical isolation, fast response time, noise immunity, and digital
logic compatibility.
