DESCRIPTION
The SFH67xx high speed optocoupler series consists
of a GaAlAs infrared emitting diode, optically coupled
with an integrated photodetector. The detector incor-
porates a Schmitt-Trigger stage for improved noise
immunity. Using the Enable input, the output can be
switched to the high ohmic state, which is necessary
for data bus applications. A Faraday shield provides
a common mode transient immunity of 1000 V/
µ
s at
V
CM
=50 V for SFH6700/01/02/05 and 2500 V/
µ
s at
V
CM
=400 V for SFH6711/12/19.
The SFH67xx uses an industry standard DIP8 pack-
age. With standard lead bending, creepage distance
and clearance of
≥
7.0 mm with lead bending options
6, 7, and 9
≥
8 mm are achieved.
