*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 greater than those indicated

in the operational sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect reliability.

OPERATING CURRENT CHARACTERISTICS

NOTES:

1. Measured with outputs open.

2. Refresh period is 64ms.
