The 'ABTH162260 are 12-bit to 24-bit multiplexed D-type latches used in applications where two 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 are also useful in memory-interleaving applications.

Three 12-bit I/O ports (A1-A12, 1B1-1B12, and 2B1-2B12) are available for address and/or data transfer. The output-enable (OE1B\, OE2B\, and OEA\) inputs control the bus-transceiver functions. The OE1B\ and OE2B\ control signals also allow bank control in the A-to-B direction.

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