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.

= 25 C
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Ratings for extended periods of time can adversely affect reliability.
