HD74HCT640 Datasheet - Hitachi Semiconductor

HD74HCT640 Octal Bus Transceivers (with 3-state outputs)

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 other. The HD74H.

HD74HCT640 Features
