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).
