Optoisolator
Features
Compact, moisture resistant package
Low LED current
Passive resistance output
Description
This optoisolator consists of an LED input optically
coupled to a photocell. The photocell resistance is
high when the LED current is "off" and low resistance
when the LED current is "on".
