MC34017 - Motorola

MC34017 TELEPHONE TONE RINGER BIPOLAR LINEAR

Pin 1, 8 5 4 2, 3 7 6 Symbol AC1, AC2 RS RI RO1, RO2 RG RC Description The input terminals to the full–wave diode bridge. The ac ringing signal from the telephone line energizes the ringer through this bridge. 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.
