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 electromechan-
ical relays in many applications. It is constructed
using a GaAs LED for actuation control and an inte-
grated 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, it employs current-limiting circuitry which
meets FCC 68.302 and other regulatory voltage
surge requirements when overvoltage protection is
provided.
