DESCRIPTION
The LH1514 is a DPST normally open (2 Form A) SSR that can be
used in balanced high-frequency applications like T1 switching. With
its low ON-resistance and high actuation rate, the LH1514 is also very
attractive as a general-purpose 2 Form A SSR for balanced signals.
The relays are constructed using a GaAlAs LED for actuation control
and an integrated monolithic die for the switch output. The die, fabri-
cated in a dielectrically isolated Smart Power BiCMOS, is comprised
of a photodiode array, switch control circuitry, and NMOS switches.
In balanced switching applications, internal circuitry shunts high-fre-
quency signals between two poles when the SSR is off. This bal-
anced T termination technique provides high isolation for the load.

Absolute Maximum Ratings, TA=25°C
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.
