Octal Bus Transceivers (with 3-state outputs)

Description Both the HD74HCT640 and the HD74HCT643 have one active low enable input (G), and a direction control (DIR). When the DIR input is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from B to A. The HD74HCT640 transfers inverted data from one bus to the o
