SN74LVCR2245A OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS www.ti.com SCAS581M – NOVEMBER 1996 – REVISED MARCH 2005 DESCRIPTION/ORDERING INFORMATION (CONTINUED) 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.
