Stresses in excess of the Absolute Maximum Ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to maximum rating conditions for extended periods can adversely affect device reliability.

† Refer to Current Limit Performance Application Note for a discussion on relay operation during transient currents.DescriptionThe LH1505AAC contains two normally open switches that can be used as two independent SPST relays or as one DPST relay. The relay is constructed using a GaAlAs LED for actuation control and integrated monolithic dies for the switch outputs. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuity, and DMOS switches. In addition, the LH1505AAC relay employs currentlimiting circuity, enabling it to pass FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided.
