Notes: 1. If CE1s goes LOW (or CE2s goes HIGH) coincident with or after WE goes LOW, the
output will remain at high impedance.
2. If CE1s goes HIGH (or CE2s goes LOW) coincident with or before WE goes HIGH, the
output will remain at high impedance.
3. If OE is HIGH during the write cycle, the outputs will remain at high impedance.
4. Because I/O signals may be in the output state at this Time, input signals of reverse
polarity must not be applied.
