DESCRIPTION

typ.
The LH1539 telecom switch consists of an optically iso-
lated solid state relay (SSR) Form A and a bidirectional
input optocoupler in a single 8-pin package. The SSR is
ideal for switchhook and dial-pulse switching while the
optocoupler performs ring detect and loop current sens-
ing functions. Both the SSR and optocoupler provide
Part Identification

The SSR is integrated on a monolithic receptor die using
smart power technology. The SSR features low ON-
resistance, high breakdown voltage, and current-limit cir-
cuitry that protects the relay from telephone line induced
lightning surges.
The optocoupler provides bidirectional current sensing
via two antiparallel GaAs infrared emitting diodes. Very
high current transfer ratio (CTR) is achieved by coupling
to a photodarlington transistor. This high CTR allows the
user to minimize the size of the ring detector capacitor.

Absolute Maximum Ratings, T =25°C
Recommended Operating Conditions
A
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.
