description  
The ABT32245 are 36-bit (quad 9-bit) noninverting 3-state transceivers designed for synchronous two-way  
communication between data buses. The control-function implementation minimizes external timing  
requirements.  
These devices can be used as four 9-bit transceivers, two18-bit transceivers, or one 36-bit transceiver. They  
allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic  
level at the direction-control (DIR) inputs. The output-enable (OE) inputs can be used to disable the device so  
that the buses are effectively isolated.

Products conform to specifications per the terms of Texas Instruments
