HD74HC640 - Octal Bus Transceivers

Each device has an active enable G and a direction control input, DIR.

when DIR is high, data flows from the A inputs to the B outputs.

When DIR is low, data flows from the B inputs to the A outputs.

The HD74HC640 transfers inverted data from one bus to other and the HD74HC643 transfers inverted dat
