Description
The LH1529FP and LH1529GP Telecom switches
consist of an optically coupled solid state relay (SSR)
and a bidirectional input optocoupler. The SSR is
ideal for performing switch hook and dial-pulse
switching while the optocoupler performs ring detec-
tion and loop current sensing functions. Both the SSR
and opto coupler provide 3000 V_RMS of input to output
isolation.
The SSR is integrated on a monolithic receptor die
using high voltage 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.
The opto channel provides a minimum CTR of 33 %
at 6.0 mA.
The LH1529FP and LH1529GP come in an 8 pin,
0.080 inch thick plastic flat pak, SMD.
