LH1546AAB

Absolute Maximum Ratings, TA=25°C
Stresses in excess of the Absolute Maximum Ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional opera- tion 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 maximumrating conditions for extended periods can adversely affect device reliability.

The LH1546AAB is robust, ideal for telecom and ground fault applications. It is a SPST normally open switch (1 Form A) that replaces electromechanical relays in many applications. It is constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. In addition, LH1546AAB employs current-limiting cir- cuitry which meets FCC 68.302 and other regulatory voltage surge requirements when overvoltage protec- tion is provided.
