† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage value is with respect to GND.

NOTES: 2. To avoid possible damage to these CMOS devices and resulting reliability problems, the following sequence should be followed when
applying power:
1. Connect to GND.
2. Connect VCC.
3. Connect the input signals.
When removing power, follow the preceding steps in reverse order.
3. Voltages at analog inputs and outputs and VCC are with respect to GND.
4. RL and CL should not be applied simultaneously.
