Telecom Switch - 1 Form A Solid-State Relay

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

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.
