1, 8
AC1, AC2
The input terminals to the full-wave diode bridge. The AC ringing signal from the
telephone line energizes the ringer through this bridge.
5
RS
The input of the threshold comparator to which diode bridge current is mirrored and
sensed through an external resistor (R3). Nominal threshold is 1.2 V. This Terminal
internally clamps at 1.5 V.
4
RI
The positive supply terminal for the oscillator, frequency divider, and output buffer
circuits.
2, 3
RO1, RO2
The tone ringer output terminals through which the sound element is driven.
7
RG
The negative terminal of the diode bridge and the negative supply terminal of the tone
generating circuitry.
6
RC
The oscillator terminal for the external resistor and capacitor which control the tone
ringer frequencies (R2, C2).
