Octal Bus Transceivers (inverted 3-state outputs)

REJ03D0487–0200

Rev.2.00

Feb.18.2005

This octal bus transceivers is designed for asynchronous two-way communication between data buses. The device

transmit 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 that the buses are effectively isolated.
