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 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 10ns
maximum, and is limited to < 20mA for the period of VTERM > VCC + 10%.
3. Ambient Temperature Under DC Bias. No AC Conditions. Chip Deselected.

NOTES:
1. These parameters are determined by device characterization, but are not
production tested.
2. 3dV references the interpolated capacitance when the input and output
switch from 0V to 3V or from 3V to 0V.
3. COUT also references CI/O.

NOTES:
1. This is the parameter TA. This is the "instant on" case temperature.
NOTES:
1. VTERM must not exceed VCC + 10%.
2. V
