DESCRIPTION
The 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 detection and loop current
sensing functions. Both the SSR and optocoupler provide
3000 V_RMS of input to output 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 anti parallel GaAs infrared emitting diodes. The opto
channel provides a minimum CTR of 33 % at 6 mA.
The LH1529FP and LH1529GP come in an 8 pin, 0.080"
thick plastic flat pak, SMD.
