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.
