DESCRIPTION

The LH1529A and LH1529B Telecom switches consist

of an optically coupled solid state relay (SSR) and a

bidirectional input optocoupler. The SSR is ideal for per-

forming switchhook and dial-pulse switching while the

optocoupler performs ring detection and loop current

sensing functions. Both the SSR and optocoupler pro-

The SSR is integrated on a monolithic receptor die using

high voltage technology. The optocoupler provides bidi-

rectional current sensing via two antiparallel GaAs infra-

red emitting diodes. The opto channel provides a

minimum CTR of 33% at 6.0 mA.
