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 cou-
pler 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 ON-
resistance, high breakdown voltage and current-limit cir-
cuitry 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.
