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.
