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 this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect reliability.
2. V
TERM must not exceed VDD + 150mV for more than 25% of the cycle time
or 4ns maximum, and is limited to
< 20mA for the period of VTERM > VDD
+ 150mV.
3. Ambient Temperature under DC Bias. No AC Conditions. Chip Deselected.
