This device has an output enable (OE) pin that functions according to . When the outputs of the device are disabled, they are placed into a high impedance state where it will neither source nor sink current. High-impedance outputs are also commonly referred to as three-state or tri-state outputs. The maximum leakage for the output in this state is defined by IOZ in the Electrical Characteristics: SN74LVCH245A table.
