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.
