Description

A Telecom Switch consists of an optically isolated, SPST solid-state relay (SSR) and a bidirectional input optocoupler in a single package. The LH1549AACTR is ideal for performing switch hook and dial-pulse switching while the optocoupler performs ring detect and loop current sensing functions.

The LH1549AACTR is integrated on a monolithic receptor die. It features low ON-resistance, high breakdown voltage, and current-limit circuitry that protects the relay from telephone line induced lightning surges.

The optocoupler provides bidirectional current sens- ing via two anti parallel GaAIAs infrared emitting diodes. The optocoupler provides a minimum current transfer ratio (CTR) of 33 %.
