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.
Isolation test voltage, 5300 V
RMS
TTL compatible
Bit rates: 1 MBit/s
High common mode transient immunity
Bandwidth 2 MHz
Open collector output
Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
AGENCY APPROVALS

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
(1)
Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
