DESCRIPTION
The LH1503 relays are DPST normally open switches
(2 Form A) that can replace electromechanical relays in
many applications. The relays are constructed using a
GaAlAs 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 circuity,
and DMOS switches. In addition, these relays employ
current-limiting circuity, enabling them to pass FCC
68.302 and other regulatory voltage surge requirements
when overvoltage protection is provided.

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 maximum
rating conditions for extended periods can adversely affect device reliability.
