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.

Address and/or data information can be stored using the internal storage latches/flip-flops.
