DESCRIPTION
The IL329 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 opto- coupler performs ring detection and loop current sensing functions. Both the SSR and opto coupler provide 2500 VRMS of input to ouput isolation. The SSR is integrated on a monolithic receptor die using high voltage BCDMOS technology. The SSR features low ON-resistance, high breakdown volt- age 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 IL329 comes in a 18 pin, plastic surface mount package.
