Output Drivers

Active output drivers in the FDC37N869 will always achieve the minimum specified DC Electrical Characteristics

shown in Table 120.

Note: If there is a pull-up on an external node driven by an active output driver the FDC37N869 may sink current

from the pull-up through the low impedance source.
