6. If /OE,/CE and /WE are in the read mode during this period, the I/O pins are in the output low-Z state. Inputs of

opposite phase of the output must not be applied because bus contention can occur.

7. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and

write cycle.

8. If /CE goes low simultaneously with /WE going low or after /WE going low, the outputs remain high impedance state.

10. When /CE is low: I/O pins are in the output state. The input signals in the opposite phase leading to the output

should not be applied.
