U74HCT640 OCTAL BUS TRANSCEIVERS

The U74HCT640 is a octal bus transceivers with 3-state outputs. It is designed for asynchronous two-way communication between data buses. Depending on the direction-control (DIR) input, data are transmitted from the A bus to the B bus or from B bus to the A bus. When OE is high, the buses are effect.
