2 / 19 page SN74AVC20T245 20BIT DUALSUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3STATE OUTPUTS SCES566F − MAY 2004 − REVISED APRIL 2005 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 description/ordering information (continued) The SN74AVC20T245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input is used to disable the outputs so that the buses are isolated. The SN74AVC20T245 is designed so that the control (1DIR, 2DIR, 1OE, and 2OE) inputs are supplied by VCCA. 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 VCC isolation feature ensures that if either VCC input is at GND, both ports are in the high-impedance state. 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. terminal assignments 12 34 5 6 A 1B1 1B2 1DIR 1OE 1A2 1A1 B 1B3 1B4 GND GND 1A4 1A3 C 1B5 1B6 VCCB VCCA 1A6 1A5 D 1B7 1B8 GND GND 1A8 1A7 E 1B9 1B10 1A10 1A9 F 2B1 2B2 2A2 2A1 G 2B3 2B4 GND GND 2A4 2A3 H 2B5 2B6 VCCB VCCA 2A6 2A5 J 2B7 2B8 GND GND 2A8 2A7 K 2B9 2B10 2DIR 2OE 2A10 2A9 FUNCTION TABLE (each 10-bit section) INPUTS OPERATION OE DIR OPERATION L L B data to A bus L H A data to B bus H X Isolation GQL OR ZQL PACKAGE (TOP VIEW) J H G F E D C B A 2 13 4 6 5 K |
