output. The device consists of four phototransistors
as detectors. Each channel is individually controlled.
The optocoupler is housed in a SOT223/10 package.
All the cathodes of the input LEDs and all the collec-
tors of the output transistors are common enabling a
pin count reduction from 16 pins to 10 pins-a signifi-
cant space savings as compared to four channels that
are electrically isolated individually.

Absolute Maximum Ratings
T
amb
= 25 擄C, unless otherwise specified
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Rating for extended periods of the time can adversely affect reliability.
