Absolute Maximum Ratings(1)

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. 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%.

NOTES:

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.
