NOTES:
1. Undershoot of V
IL > -1.5V for pulse width less than 10ns is allowed.
2. V
TERM must not exceed VDDQ + 100mV.
3. To select operation at 2.5V levels on the I/Os and controls of a given port, the
OPT pin for that port must be set to V
IL (0V), and VDDQX for that port must be supplied
as indicated above.
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 Bias. No AC Conditions. Chip Deselected.
NOTES:
1. This is the parameter TA. This is the "instant on" case temperature.
