Notes
1 All voltages are with respect to
GND
.
2 This is a stressrating onlyand functional operationof thedeviceat theseor anyother conditions
beyond those indicated in the operating sections of this specification is not implied. Stresses
greater than those listed may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
3 This devicecontains circuitrytoprotecttheinputs againstdamage causedbyhighstaticvoltages
or electrical fields. However, it is advised that normal precautions be taken to avoid application
of any voltage higher than the absolute maximum rated voltages to this high impedance circuit.
Unused inputs should be tied to an appropriate logic level such as
VDD
or
GND
.
4 The input current applies to any input or output pin and applies when the voltage on the pin is
between
GND
and
VDD
.
