DESCRIPTION

The LH1512 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 mult.­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.

Absolute Maximum Ratings, T

Stresses in excess of the Absolute Maximum Ratings can cause permanent
damage to the device. These are absolute stress ratings only. Functional opera­tion 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.
