NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS 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 the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. V TERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns

tested.
2. 3dV references the interpolated capacitance when the input and output signals
switch from 0V to 3V or from 3V to 0V.
