74LS640 Datasheet

Octal Bus Transceivers

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

74LS640 Overview

OCTAL BUS TRANSCEIVERS These octal bus transceivers are designed for asynchronous two-way munication between data buses. Control function implementation minimizes external timing requirements. These circuits allow data transmission from the A bus to B or from the B bus to A bus depending upon the logic level of the direction control (DIR) input.
