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.

1. H = VIH, L = VIL, X = Don't Care (VIL or VIH)
2. SUB, SLB (Upper, Lower Byte Enable). These active LOW inputs allow individual bytes to be written or read. When SLB is
LOW, data is written or read to the lower byte, I/O0 - I/O8. When SUB is LOW, data is written or read to the upper byte, I/O9
- I/O16.
