DESCRIPTION
The LH1529FP and LH1529GP Telecom switches con-
sist 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 opto coupler pro-
vide 3000 V
RMS
of input to ouput isolation.
The SSR is integrated on a monolithic receptor die using
high voltage technology. The SSR 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 sensing
via two antiparallel GaAs infrared emitting diodes. The
opto channel provides a minimum CTR of 33% at 6.0 mA.
The LH1529FP and LH1529GP come in an 8 pin, 0.080
inch thick plastic flat pak, SMD.
