com LH1529 OPTICALLY COUPLED TELECOM SWITCH Preliminary Data Sheet FEATURES • Solid State Relay and Optocoupler in One Package • Package—Single 8 Pin DIP • l/O Isolation, 3750 VRMS • Surface Mount Option • Optocoupler – Bidirectional Current Detection • Solid-state Relay – Typical RON 20 Ω – Load Voltage 350 V – Load Current 120 mA – Current Limit Protection – High Surge Capability – Linear, AC/DC Operation – Clean Bounce Free Switching – Low Power Consumption – High Reliability Monolithic Receptor APPLICATIONS • General Telecom Switching – On/off Hook Control – Dial Pulse – Ring Current Detection – Loop Current Sensing Description The LH1529 Telecom switch consists of an optically coupled solid state relay (SSR) and a bidirectional input optocoupler.
The SSR is ideal for performing switchhook and dial-pulse switching while the optocoupler performs ring detection and loop current sensing functions.
Both the SSR and opto coupler provide 3750 VRMS of input to ouput isolation.
The SSR is integrated on a monolithic receptor die using high voltage BCDMOS technology.
The SSR features low ONresistance, 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 mA.
The LH1529 comes in a 8 pin, plastic DIP.
To order packages with “S” bend leads, specify LH1529X00S.
