SN74AC245-EP Overview
/ordering information The SN74AC245 octal bus transceiver is designed for asynchronous two-way munication between data buses. The control-function implementation minimizes external timing requirements. When the output-enable (OE) is low, the device passes noninverted 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.
