Description
The LH1556FP is robust, ideal for telecom and
ground fault applications. It contains two SPST nor-
mally open switches (1 Form A) that replace electro-
mechanical relays in many applications. It is
constructed using a GaAs LED for actuation control
and an integrated monolithic die for the switch output.
The die, fabricated in a high-voltage dielectrically iso-
lated BCDMOS technology, is comprised of a photo-
diode array, switch control circuitry and MOSFET
switches. In addition, it employs current-limiting cir-
cuitry which meets FCC 68.302 and other regulatory
voltage surge requirements when overvoltage protec-
tion is provided.
