Write Cycle No WE Controlled17, 21, Data I/O

CY62147DV30

Write Cycle No. 1 (WE Controlled)[17, 21, 22]

DATAIN

NOTE 23

tHZOE

Notes:

21.Data I/O is high impedance if OE = VIH.

22.If CE goes HIGH simultaneously with WE = VIH, the output remains in a high-impedance state.

23.During this period, the I/Os are in output state and input signals should not be applied.
