DESCRIPTION
The LH1505 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-volt-
age dielectrically isolated technology, is comprised of a
photodiode array, switch control circuity, and DMOS
switches. In addition, the LH1505 relay employs current-
limiting circuity, enabling it to pass FCC 68.302 and
other regulatory voltage surge requirements when over-
voltage protection is provided.
