(1) 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.
(2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.

(1) All unused control inputs of the device must be held at V
CC
or GND to ensure proper device operation. Refer to the TI application report,
Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
(2) Proper connection sequence for use of the B-port I/O precharge feature is GND and BIAS V
CC
= 3.3 V first, I/O second, and V
CC
= 3.3 V
last, because the BIAS V
CC
precharge circuitry is disabled when any V
CC
pin is connected. The control inputs can be connected at any
time, but normally are connected during the I/O stage. If B-port precharge is not required, any connection sequence is acceptable, but
generally, GND is connected first.
