description  
The ’ABTH16460 are 4-bit to 1-bit multiplexed  
registered transceivers used in applications  
where four separate data paths must be  
multiplexed onto or demultiplexed from a single  
data path. Typical applications include  
multiplexing and/or demultiplexing of address and  
data  
information  
in  
microprocessor  
or  
bus-interface applications. These devices also  
are useful in memory-interleaving applications.  
Five 4-bit I/O ports (1A–4A, 1B1–4, 2B1–4, 3B1–4, and 4B1–4) are available for address and/or data transfer.  
The output-enable (OEB, OEB1–OEB4, and OEA) inputs control the bus-transceiver functions. These control  
signals also allow 4-bit or 16-bit control, depending on the OEB level.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
