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-
vide 5300 VRMS of input to output isolation.
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.
