DESCRIPTION
The LH1547 is a SPST normally open unidirectional relay that can switch dc signals. The relay is constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuitry, and a DMOS switch.
