DESCRIPTION
The CNY17F is an optocoupler consisting of a gallium
arsenide infrared emitting diode optically coupled to a
silicon planar phototransistor detector in a plastic plug-in
DIP-6 package.
The coupling device is suitable for signal transmission
between two electrically separated circuits. The potential
difference between the circuits to be coupled is not allowed
to exceed the maximum permissible reference voltages.
In contrast to the CNY17 series, the base terminal of the
F type is not conected, resulting in a substantially improved
common-mode interference immunity.

FEATURES
• Isolation test voltage, 5000 VRMS
• No base terminal connection for improved
common mode interface immunity
• Long term stability
• Industry standard dual-in-line package
• Material categorization: For definitions of
compliance please see www.vishay.com/doc?99912
