DM74ALS640A - Inverting Octal Bus Transceiver

General Description

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 the direction control (DIR) input.

Key Features

  • s Advanced Oxide-isolated Ion-implanted Schottky TTL process s Switching performance is guaranteed over full temperature and VCC supply range s Switching performance specified at 50 pF s PNP input design reduces input loading Ordering Code: Order Number DM74ALS640AWM DM74ALS640AN Package Number M20B N20A Package.

DM74ALS640A Inverting Octal Bus Transceiver August 1985 Revised February 2000 DM74ALS640A Inverting Octal Bus Transceiver General Description 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 the direction control (DIR) input. The enable input (G) can be used to disable the device so the busses are effectively isolated.
