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.
