† 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.

NOTES:

1. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.

2. This value is limited to 5.5 V maximum.

3. The package thermal impedance is calculated in accordance with JESD 51-7.

4. The package thermal impedance is calculated in accordance with JESD 51-5.

‡ With supply voltages at or near 2 V, the analog switch on-state resistance becomes very nonlinear. It is recommended that only digital signals

be transmitted at these low supply voltages.

NOTE 5: All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to TI application report Implications

of Slow or Floating CMOS Inputs, literature number SCBA004.
