Description

The SN54ABT16260 and SN74ABTH16260 are 12-bit to 24-bit multiplexed D-type latches used in applications in which two separate data paths must be multiplexed onto, or demultiplexed from, a single data path. Typical applications of SN54ABT16260 and SN74ABTH16260 include multiplexing and/or demultiplexing of address and data information in microprocessor or bus-interface applications. This SN54ABT16260 and SN74ABTH16260 device is also useful in memory-interleaving applications.Three 12-bit I/O ports (A1A12, 1B11B12, and 2B12B12) 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.
