These optoisolators contain two
pairs of emitters and detectors
packaged in a unique configur-
ation to allow simultaneous,
isolated, bi-directional transmit
and receive capability in a single
package. Separate photo-detector
and output stage allows a speed
performance hundreds of times
faster than a conventional photo-
transistor coupler by minimizing
the base-collector capacitance
and charge storage effects.

appropriate care is required so as
not to overdrive the LEDs.
• Remote Isolation Sensing
A 0.1 µF bypass capacitor must be connected between pins 1 and 3, and between pins 5 and 7.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this
com-ponent to prevent damage and/or degradation which may be induced by ESD.
