DESCRIPTION
The LH1546AD (4 Pin DIP) 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
GaAs LED for actuation control and an integrated mono-
lithic die for the switch output. The die, fabricated in a
high-voltage dielectrically isolated BCDMOS technol-
ogy, is comprised of a photodiode array, switch control
circuitry and MOSFET switches. In addition, it employs
current-limiting circuitry which meets FCC 68.302 and
other regulatory voltage surge requirements when over-
voltage protection is provided.
