Optocoupler
Features
Compact, moisture resistant package
Low "on" resistance
Low LED current
Fast rise and decay time
Passive resistance output
Best distortion characteristics
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 when the LED current is "on".
