DESCRIPTION
The SFH6325 and SFH6326 are dual channel optocouplers
with a GaAIAs infrared emitting diode, optically coupled with
an integrated photo detector which consists of a photo
diode and a high-speed transistor in a DIP-8 plastic
package. Signals can be transmitted between two
electrically separated circuits up to frequencies of 2 MHz.
The potential difference between the circuits to be coupled
should not exceed the maximum permissible reference
voltages.
