suppliers of SII3811ACNU and PDF data of SII3811ACNU

are common l/0 devices, data should not be driven into the device while the outputs are active. The Output Enable (OE) can be deasserted HIGH before presenting data to the DQ and DQP (DQa b c,d,e,f,g}h/DQPa b,c}de,fg<h for CY7C1474V25, DQa,b,c,d/DQPa,b,c,d-for CY7C1470V~5 and DQa,b/DQPa,b for CY7C1472V25) inputs. Doing so will three-state the output drivers. As a safety precaution, DQ and DQP (DQa b,c,d,e,f,g,D/ DQPa,b,c,d,e,f,g,h for CY7C1474V25, DQa,b,c,d/DQPa,b,c,d"for CY7C1470V25 and DQa,b/DQPa,b for CY7C1472V25) are automatically three-stated during the data portion of a Write cycle, regardless of the state of OE.
