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