Description
The MCA230/ MCA231/ MCA255 are industry standard optocouplers, consisting of a gallium arsenide
infrared LED and a silicon photodarlington. These
optocouplers are constructed with a high voltage
insulation packaging process which offers 7.5 kV

Absolute Maximum Ratings
T
= 25 °C, unless otherwise specified
amb
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.
