DESCRIPTION

The LH1501 relays are SPST normally closed switches

(1 form B) that can replace electromechanical relays in many

applications. The relays are constructed as a multi-chip

hybrid device. Actuation control is via an infrared LED. The

output switch is a combination of a photodiode array with

MOSFET switches and control circuity. The relays can be

configured for AC/DC or DC only operation.
