PRODUCTION DATA
Similar to the data I/O's, floating control inputs can cause high current consumption. This device has integrated weak static pull-downs of 5-MΩ typical on the control inputs (DIR and OE) to help avoid this concern. These pull-downs are always present. For example, if the DIR pin is left floating, then the B port will be configured as an input and the A port will be configured as an output.
