Write Cycle No WE Controlled15, 19, Data I/O

CY62146DV30

Write Cycle No. 1 (WE Controlled)[15, 19, 20]

DATAIN

NOTE 21

tHZOE

Notes:

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

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

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