SN74ALVC16260

The SN74ALVC16260 is a 12-bit to 24-bit multiplexed D-type latch 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 address and data information in microprocessor or businterface applications. SN74ALVC16260 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.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.Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.The SN74ALVC16260 is available in TI's shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.

The SN74ALVC16260 is characterized for operation from 40°C to 85°C.
