1. This parameter is determined by device characterization, 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.

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-

INGS 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.
