NOTES: (see electrical characteristics sheet)
1. Initial supply voltage (V_SI) is the supply voltage required to start tone ringer oscillation
2. Sustaining voltage (V_SUS) is the supply voltage required to maintain oscillation.
3. V_TR and I_TR are the conditions applied to trigger to start oscillation for V_SUS ≤ V_CC ≤ V_SI
4. V_DIS and l_DIS are the conditions applied to trigger to inhibit oscillation for V_SI ≤ V_CC
5. Trigger current must be limited to this value externally.
