Three-Tone Ringer for Telephone Sets
U4076B
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.
Features
D Three-tone ringing sequence with 800 Hz, 1067 Hz
and 1333 Hz
D Sequence frequency adjustable between 2.5 Hz and
25 Hz
D Adjustable volume
D Push-pull output stage
D Piezo transducer or loudspeaker connection
D Common input for frequency and call recognition
D Reduced pulse duration for electromagnetic
transducers
D Clock oscillator with ceramic resonator or LC series
cct possible
D Input protective diode
D On-chip rectifier bridge
D Protection circuit against ringing in a parallel circuit
