descriptionThe 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 include
multiplexing and/or demultiplexing of address and
data information in microprocessor or
bus-interface applications. This device is 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. The latch-enable (LE1B,
LE2B, LEA1B, and LEA2B) inputs are used to control data storage. When the latch-enable input is high, the
latch is transparent. When the latch-enable input goes low, the data present at the inputs is latched and remains
latched until the latch-enable input is returned high.
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.
