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
mult.-chip hybrid device. Actuation contral 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..

Stresses in excess of the Absolute Maximum Ratings can cause permanent
damage to the device. These are absolute stress ratings only. Functional opera-
tion of the device is not implied at these or any other conditions in excess of
those given in the operational sections of the data sheet. Exposure to maximum
rating conditions for extended periods can adversely affect device reliability.
