TRI-STATEÉ Octal Bus Transceiver
General Description
These octal bus transceiversare designedfor asynchro-
nous two-way communication between data buses. The
control function implementation minimizes external timing
requirements.
The device allowsdata transmission fromtheAbustotheB
busor fromthe Bbustothe Abusdepending uponthe logic
levelatthe direction control (DIR) input. The enable input
(G)canbe usedto disablethe devicesothatthe busesare
effectively isolated.
