DESCRIPTION
The LH1532FP is a Dual 1 Form A (SPST) which can
replace electromechanical relays in many applications.
They are constructed using a GaAlAs LED for activation
control and an integrated monolithic die for the switch
output. The die is comprised of a photodiode array,
switch control circuity and MOSFET switches. The SSR
features low ON-resistance, high breakdown voltage
and current-limit circuitry that protects the relay from
telephone line induced lightning surges.
The LH1532FP comes in an 8 pin, 0.080 inch thick plas-
tic Flat Pack: surface mount leads with100 mil spacing.

Stresses in excess of the absolute Maximum Ratings can cause permanent
damage to the device. These are absolute stress ratings only. Functional oper-
ation 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.
