High Speed Optocoupler, Single, 5 MBd, in SOIC-8 Package

DESCRIPTION

The single channel 5 Mb/s SFH6720 and SFH6721 high

speed optocoupler consists of a GaAlAs infrared emitting

diode, optically coupled with an integrated photo detector.

The detector incorporates a Schmitt-trigger stage for

improved noise immunity. A Faraday shield provides a

common mode transient immunity of 1000 V/μs at

SFH6721.
