DescriptionThe LH1529FP and LH1529GP Telecom switches consist of an optically coupled solid state relay (SSR) and a bidirectional input optocoupler. The SSR is ideal for performing switch hook and dial-pulse switching while the optocoupler performs ring detec- tion and loop current sensing functions. Both the SSR and opto coupler provide 3000 VRMS of input to output isolation.
The SSR LH1529GP 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 LH1529GP provides bidirectional current sens- ing via two anti parallel 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.
