U4076B General Description
The three-tone ringing integrated circuit U4076B, in conjunction with a piezo transducer or loudspeaker replaces the normal electromechanical telephone bell. It is operated with the ringing current from the exchange.
There is also a possibility of operating the IC with the dc supply voltage, being developed for large operating range. The integrated circuit is overload protected.
