DESCRIPTION

The LH1502 relays contain normally open and normally

closed switches that can be used independently as a 1 form

A and 1 form B relay, or when used together, as a 1 form C

relay. 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.
