Description

These SSRs (LH1541, 1 Form A) are SPST normally

open switches which can replace electromechanical

relays in many applications. The relays provide a low

capacitance, high-voltage switch contact with high off

resistance and low switch-offset voltage. These char-

acteristics, combined with high-speed actuation,

result 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 photo-

diode array, switch-control circuity, and low-capaci-

tance MOSFET switches.

Order Information

Absolute Maximum Ratings

Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. 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.
