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 + 10% for more than 25% of the cycle time or 10%
maximum, and is limited to < 20mA for the period of VTERM > Vcc + 10%.

1. These parameters are determined by device characterization but are not
production tested (TQFP Package only).
2. 3dV references the interpolated capacitance when the input and output signals
switch from 0V to 3V or from 3V to 0V.
