*Note:
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage of the device.
Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
Operating Currents TA = 0 to 70 °C(Commercial)/-40 to 85 °C(Extended);
VSS = 0 V; VCC= 2.5 V,VCCQ = 1.8V(Recommended Operating Conditions unless otherwise noted)
Notes:
7.
These parameters depend on the cycle rate and these values are measured by the cycle rate under the minimum value of tCK and
tRC. Input signals are changed one time during tCK.
8.
These parameter depend on output loading. Specified values are obtained with output open.
