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
standard warranty. Production processing does not necessarily include
testing of all parameters.
