SN74HCT645 OCTAL BUS TRANSCEIVERS

ordering information These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable (OE) inpu.
