Description
The FODM8071 is a 3.3 V / 5 V high−speed logic gate output
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−immunity, characterized by high common mode
rejection specifications.
This high−speed logic gate output optocoupler, housed in a compact
5−pin Mini−Flat package, consists of a highspeed AlGaAs LED at the
input coupled to a CMOS detector IC at the output. The detector IC
comprises an integrated photodiode, a high−speed transimpedance
amplifier and a voltage comparator with an output driver. The CMOS
technology coupled with a high−efficiency LED achieves low power
consumption as well as very high speed (55 ns propagation delay,
20 ns pulse width distortion).
