Three-Tone Ringer for Telephone Sets

Description

The three-tone ringing integrated circuit U4076B, in There is also a possibility of operating the IC with the dc

conjunction with a piezo transducer or loudspeaker supply voltage, being developed for large operating

replaces the normal electromechanical telephone bell. It range. The integrated circuit is overload protected.

is operated with the ringing current from the exchange.

Features
