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 this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. VTERM must not exceed Vcc + 0.5V for more than 25% of the cycle time
or 10ns maximum, and is limited to < 20mA for the period of VTERM > Vcc
+ 0.5V.

1. This parameter is determined by device characteristics but is not
production tested.
2. 3dV references the interpolated capacitance when the input and
output signals switch from 0V to 3V or from 3V to 0V .
