Notes:
12. Address valid prior to or coincident with CE1 transition LOW and CE2 transition HIGH.
13. Data I/O is high-impedance if OE = VIH.
14. If CE1 goes HIGH / CE2 LOW simultaneously with WE going HIGH, the output remains in a high–impedance state.
15. CE above is defined as a combination of CE1 and CE2. It is active low.
