This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is 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. terminal assignments 1234 A A1 DIR VCC OE B A3 B2 A2 B1 C A5 A4 B4 B3 D A7 B6 A6 B5 E GND A8 B8 B7 FUNCTION TABLE INPUTS OPERATION OE DIR OPERATION L L B data to A bus L H A data to B bus H X Isolation logic diagram (positive logic) DIR OE A1 B1 To Seven Other Channels 1 2 19 18 Pin numbers shown are for the DB, DGV, DW, FK, J, N, NS, PW, RGY, and W packages.
