LH1539AAC/ LH1539AACTR/ LH1539AB - 1 Form A Photo Darlington Telecomswitch - Vishay Solid State Relays

LH1539AAC/ LH1539AACTR LH1539AB - 1 Form A Photo Darlington Telecomswitch - Vishay Solid State Relays LH1539AAC The LH1539 telecom Switch consists of an optically isolated Solid State Relay (SSR) Form A and a bidirec- tional input Optocoupler in a single 8-pin package. The SSR is ideal for Switch hook and dial-pulse switching while the Optocoupler performs ring detect and loop current sensing functions. Both the SSR and Optocoupler provide 5300 V of input-to-output iso- RMS lation voltage. The SSR is integrated on a monolithic receptor die using smart power 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 sens- ing via two anti parallel GaAs Infrared Emitting Diodes Very high current transfer ratio (CTR) is achieved by coupling to a photodarlington Transistor This high CTR allows the user to minimize the size of the ring detector capacitor.
