Description
These bi-directional dual channel
optoisolators, packaged in an
industry standard SOIC-8
package, provide full duplex and
bi-directional isolated data
transfer and communication
capability in a compact surface
mount package.
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.
The HCPL-0560 is a V
CC
common
configuration, in which anode of
the LED of one channel is
internally connected to the output
side V
CC
of the second channel.
Thus, the LED input current of
one channel now becomes a
function of the V
CC
of the second
channel in the package, and
appropriate care is required so as
not to overdrive the LEDs.
