Description

The LH1521 dual 1 Form B relays are SPST normally

closed switches that can replace electromechanical

relays in many applications. The relays are con-

structed as a multi chip hybrid device. Actuation con-

trol is via an Infrared LED. The output switch is a

combination of a photodiode array with MOSFET

switches and control circuity.
