(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. 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 value of VCC is provided in the recommended operating conditions table.

VCCI is the VCC associated with the input port.

(2)

VCCO is the VCC associated with the output port.

(3)

All unused data inputs of the device must be held at VCCI or GND to ensure proper device operation. See Implications of Slow or

Floating CMOS Inputs, SCBA004.

(4)

For VCCI values not specified in the data sheet, VIH min = VCCI × 0.7 V, VIL max = VCCI × 0.3 V.
