† 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. All voltages referenced to GND unless otherwise specified.

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

NOTES:

3. All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report,

Implications of Slow or Floating CMOS Inputs, literature number SCBA004.

4. In certain applications, the external load resistor current may include both VCC and signal-line components. To avoid drawing VCC

current when switch current flows into the transmission gate inputs, the voltage drop across the bidirectional switch must not exceed

0.6 V (calculated from ron values shown in electrical characteristics table). No VCC current flows through RL if the switch current flows

into the COM OUT/IN A terminal.
