DESCRIPTION
These SSRs (LH1541, 1 Form A) are SPST normally
open switches which can replace electromechanical
relays in many applications. The relays provide a lowcapacitance, high-voltage switch contact with high offresistance and low switch-offset voltage. These characteristics, combined with high-speed actuation, result in
an SSR which is ideal for small signal and dc instrumentation applications.
The relays are constructed by using a GaAlAs LED for
actuation control and an integrated monolithic die for
the switch output. The die is comprised of a photodiode
array, switch-control circuity, and low-capacitance MOSFET switches.

Absolute Maximum Ratings, TA=25°C
Recommended Operating Conditions
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 this document. Exposure to absolute
Maximum Ratings for extended periods of time can adversely affect reliability.
