2 / 21 page www.ti.com DESCRIPTION/ORDERING INFORMATION (CONTINUED) GQN OR ZQN PACKAGE (TOP VIEW) 1 2 3 4 A B C D E SN74LVCR2245A OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS SCAS581M – NOVEMBER 1996 – REVISED MARCH 2005 This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The SN74LVCR2245A 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 can be used to disable the device so the buses are effectively isolated. All outputs, which are designed to sink up to 12 mA, include equivalent 26- Ω resistors to reduce overshoot and undershoot. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. 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. 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.
