SpecificationsAbsolute Maximum Ratings, T A =25
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.

DescriptionThe LH1514AAC 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 LH1514AAC are constructed using a GaAlAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated 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-frequency signals between two poles when the SSR is off. This balanced T termination technique provides high isolation for the load.
