SDN137
Digital High Speed Optocoupler
10MBd, Logic Output
Description
The SDN137 consists of a high efficient AlGaAs Light
Emitting Diode and a high speed optical detector. This
design provides excellent AC and DC isolation between the
input and output sides of the Optocoupler.
The output of the optical detector features an open
collector Schottky clamped transistor. The enable function
allows the optical detector to be strobed. The internal
shield ensures high common mode transient immunity. A
guaranteed common mode transient immunity is up to
15,000V/μS.
The SDN137 comes standard in an 8 pin DIP package.
Applications
 High Speed Logic Ground Isolation
 Replace Slower Speed Optocouplers
 Line Receivers
 Power Transistor Isolation
 Pulse Transformer Replacement
 Switch Mode Power Supplies
 Digital Fieldbus Isolation
 Ground Isolation – Analog Signals
