DESCRIPTION
The LH1539 telecom switch consists of an optically isolated 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 sensing functions. Both the SSR and optocoupler provide
5300 VRMS of input-to-output isolation voltage.
The SSR is integrated on a monolithic receptor die using
smart power technology. The SSR features low ONresistance, high breakdown voltage, and current-limit circuitry 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.
