However, precautions must be taken to avoid applications of any voltage higher than 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 voltage level (e.g.,either GND or Vcc). Unused outputs must be left open.

Ringing Start Voltage (4) Vtr See Figure 1 --36 Notes : 1. Initiation supply voltage (VSI) is the supply voltage required to start the tone ringer oscillating. 2. Sustaining voltage (VSUS) 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 specific.
