pins must be connected to the power supply.
2. All GND pins must be connected to the ground supply
Absolute Maximum Ratings
(1)
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUMRATINGS may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Exposure
to absolute maximumrating conditions for extended periods may affect
reliability.
2. V

must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum and is limted to < 20mA for the period of V

(T
A
= +25°C, f = 1.0MHz) TQFP only
NOTES:
1. This parameter is determned by device characterization but is not
production tested.
2. 3dV references the interpolated capacitance when the input and
the output signals switch from0V to 3V or from3V to 0V.
