2 / 11 page SN74AVC245 OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS SCES263B – APRIL 1999 – REVISED DECEMBER 1999 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 description (continued) To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 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. The SN74AVC245 is characterized for operation from –40 °C to 85°C. terminal assignments DGV, DW, OR PW PACKAGE (TOP VIEW) 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 DIR A1 A2 A3 A4 A5 A6 A7 A8 GND VCC OE B1 B2 B3 B4 B5 B6 B7 B8 FUNCTION TABLE (each transceiver) INPUTS OPERATION OE DIR OPERATION L L B data to A bus L H A data to B bus H X Isolation |
