Description
The FODM8061 is a 3.3 V/5 V high−speed logic gate output (open
collector) optocoupler, which supports isolated communications
allowing digital signals to communicate between systems without
conducting ground loops or hazardous voltages. It utilizes onsemi’s
patented coplanar packaging technology, OPTOPLANAR®, and
optimized IC design to achieve high noise immunity, characterized by
high common mode transient immunity specifications.
This optocoupler consists of an AlGaAS LED at the input,
optically coupled to a high speed integrated photo−detector logic gate.
The output of the detector IC is an open collector schottky−clamped
transistor. The coupled parameters are guaranteed over the wide
temperature range of −40°C to +110°C. A maximum input signal
of 5mA will provide a minimum output sink current of 13 mA
(fan out of 8).
