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 produc-

tion tested.

2. 3dV references the interpolated capacitance when the input and output

signals switch from 0V to 3V or from 3V to 0V .
