Note
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent
damage to the device. This is stress rating only and the functional operation of the device under these or
any other conditions above those indicated in the operation of this specification is not implied.
Exposure to the absolute maximum rating conditions for extended period may affect reliability.

Note:
1. H=VIH, L=VIL, X=don't care(VIH or VIL)
2. UB, LB(Upper, Lower Byte enable)
These active LOW inputs allow individual bytes to be written or read.
When LB is LOW, data is written or read to the lower byte, I/O1 -I/O8.
When UB is LOW, data is written or read to the upper byte, I/O9 -I/O16.
