description/ordering information
'ABT162245 devices 16-bit noninverting 3-state transceivers designed synchronous two-way communication between data buses. control-function implementation minimizes external timing requirements.
These devices used 8-bit transceivers 16-bit transceiver. They allow data transmission from from bus, depending logic level direction-control (DIR) input. output-enable (OE) input used disable device that buses effectively isolated. A-port outputs, which designed source sink include equivalent series resistors reduce overshoot undershoot. These devices fully specified partial-power-down applications using Ioff. Ioff circuitry disables outputs, preventing damaging current backflow through devices when they powered down. ORDERING INFORMATION
