Description

The FODM8061 is a 3.3V/5V 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 Fairchild’s

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 13mA

(fan out of 8).
