The outputs of the SN74AUC07 are open drain and can be connected to other open-drain outputs to implement active-low wired-OR or active-high wired-AND functions. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. www.DataSheet4U.com ORDERING INFORMATION TA PACKAGE† ORDERABLE PART NUMBER TOP-SIDE MARKING –40°C to 85°C QFN – RGY Tape and reel SN74AUC07RGYR MS07 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
