*Note : 1. Initiation supply voltage (Vsi) is a supply voltage required to start oscillation of the tone ringer.
ELECTRICAL CHARACTERISTICS
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
ABSOLUTE MAXIMUM RATINGS
2. Sustaining supply voltage (Vsus) is a supply voltage required to maintain oscillation of the tone ringer.
3. Oscillation frequency is determined by the following equations 1, 2, and 3.
