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

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.
