† _{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 clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.

In applications with fast edge rates, multiple outputs switching, and operating at high frequencies, the output may have little or no level-shifting
effect.
NOTE 3: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report,

§ _{This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.}
¶ _{Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined}
by the lower of the voltages of the two (A or B) terminals.
