DESCRIPTION
The L3234 is a monolithic integrated circuit which
is part of a kit of solid state devices for the sub-
scriber line interface. The L3234 sends a ringing
signal into a two wires analog telephone line in
balanced mode. The AC ringing signal amplitude
is up to 60Vrms, and for that purpose a positive
supply voltage of +100V shall be available on the
subscribercard.
The L3234 receives a low amplitude ringing sig-
nal (950mVrms) and provide the voltage/current
amplification (60Vrms/70mA) when the enable in-
put is active (CS > 2V). In disable mode (CS <
0.8V) the power consumption of the chip is very
low (<14mW).
The circuit is designed with a highvoltage bipolar
technology(V
CEO
> 140V / V
CBO
> 250V).
The package is a mouldedplastic power package
(Heptawatt)suitable also for surfacemounting.
