Description
The FOD0721/0720/0710 family utilizes Fairchild’s
patented coplanar packaging technology, Optoplanar
and optimized IC design to guarantee minimum 20kV/µs
Common Mode Noise Rejection (CMR) rating.
These high-speed logic gate optocouplers consist of a
high-speed AlGaAs LED driven by a CMOS IC coupled
to a CMOS detector IC, comprising an integrated photo-
diode, a high-speed transimpedance amplifier and a
voltage comparator with an output driver. The CMOS
technology coupled to the high efficiency of the LED
achieves low power consumption as well as very high
speed (40ns propagation delay, 6ns pulse width
distortion).
These devices are available in a compact 8-pin small
outline package.
