DESCRIPTION
The LH1540 relay is an SPST normally open switch
(1 form A) in small-outline packages (SOP). It requires a
minimal amount of LED drive current to operate, making
them ideal for battery powered and power consumption
sensitive 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 BCDMOS technology, is comprised of
a photodiode array, switch-control circuitry, and MOSFET
switches. In addition, the relays employ current-limiting
circuitry enabling it to pass lightning surge testing as per
ANSI/TIA-968-B and other regulatory surge requirements
when overvoltage protection is provided.
