scbs746b ? july 2000 - revised october 2003 2 post office box 655303 ? dallas, texas 75265 description/ordering information (continued) when v cc is between 0 and 1.5 v, the device is in the high-impedance state during power up or power down. however, to ensure the high-impedance state above 1.5 v, oe should be tied to gnd through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. these devices are fully specified for hot-insertion applications using i off and power-up 3-state. the i off circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. the power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict. function table (each buffer) inputs output oe a output y h h h h ll l x z logic diagram (positive logic) 1 1oe 2 1a 1y 3 4 2oe 5 2a 2y 6 10 3oe 9 3a 3y 8 13 4oe 12 4a 4y 11 pin numbers shown are for the d, db, dgv, j, ns, pw, and w packages.
