Optocoupler
Features
Compact, moisture resistant package
Lowest "on" resistance
Very low LED current
Passive resistance output
Low distortion
Ideal for applications requiring matched devices
Description
This optocoupler 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".
