1. General description
2. Features
The 74ALVT16260 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 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 to A12, 1B1 to 1B12 and 2B1 to 2B12) are available for address
or data transfer. The output enable inputs (OE1B, OE2B, and OEA) control the bus
transceiver functions. OE1B and OE2B also allow bank control in the A to B direction.
Address or data information can be stored using the internal storage latches. The latch
enable inputs (LE1B, LE2B, LEA1B and LEA2B) 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.
To ensure the high-impedance state during power-up or power-down, all output enable
inputs should be tied to V
is determined by the current sinking capability of the driver.
The 74ALVT16260 is available in a SSOP56 and a TSSOP56 package.
