IM74AL640AWM General Description
DM74ALS640A Inverting Octal Bus Transceiver This inverting octal bus transceiver is designed for asynchronous two-way communication between data busses.This device transmits data from the A bus to the B bus or from the B bus to the A bus depending upon the level at thedirection control (DIR) input. The enable input (G) can beused to disable the device so the busses are effectively isolated.
