B Absolute Maximum Rating Description Symbol Value Unit DC Supply Voltage (Referenced to GND) VCC + 36 V Power Dissipation in Still Air Plastic DIP PD 400 mW Switch Collector Voltage Tstg -65 to +150 oC Note: * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be rest ricted to the Recommended Operating Conditions. Recommended Operating Conditions Description Symbol Min Max Unit Operating Voltage Vopr 13 36 V Operating Temperature T A -45 +65 oC Note: This device contains protection circuitry circuitry to guard against damage due to high stat ic voltages or electric fidlds. However, precautions must be taken to avoid applic ations of any voltage higher t han maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≦(VIN or VOUT)≦Vcc. Unused inputs must always be tied to an appropriate logic vo ltage level (e.g.,either GND or Vcc). Unused outputs must be left open.

Initiation supply voltage (VSI) is the supply voltage required to start the tone ringer oscillating. 2. Sustaining voltage (V SUS) is the supply voltage required to maintain oscillation. 3. Ringing start voltage is the value of AC supply voltage required to start the tone ringer ringing in FIG.3 4. This product is not designed for protection against radioactive rays. 5. All data and specifications are subject to change without notice.

Figure 3. Test Circuit (2) C1 also provides isolation from DC voltages (48V) on the exchange line. for the tone ringer chip. As this voltage exceeds the initiation voltage (VSI), oscillation starts. With the components shown, the ouptut frequency chops between 512(fh1) and 640Hz(fh2) at a 10Hz(fL) rate. The loudspeaker load is coupled through a 1300W to 8W transformer. The output coupling capacitor C5 is required with transformer coupled loads. When driving a piezo-ceramic transducer type load, the coupling C5 and transformer (1300W:8W) are not required. However, a current limiting resistor is required. The low frequency oscillator oscillates at a rate (fL) controlled by an external resistor (R2) and capacitor (C2).
