Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Voltage range applied to any output in the high-impedance or power-off state.
3. Voltage range applied to any output in the high or low state, and VCC is provided in the recommended
operating conditions table.
