U74AHC640
DESCRIPTION
The U74AHC640 is a octal bus transceivers with 3-state outputs. It is designed for asynchronous two-way munication between data buses. Depending on the direction-control (DIR) input, data are transmitted from the A bus to the B bus or from the B bus to the A bus.
When OE is high, the buses are effectively isolated. When OE is low, the buses are enable.
