DESCRIPTION
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 and/or demultiplexing of address and data
information in microprocessor or bus-interface applications. This
device is alto 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.
To ensure the high-impedance state during power-up or
power-down, OE should be tied to V
CC
through a pull-up resistor;
the minimum value of the resistor is determined by the current
sinking capability of the driver.
The 74ALVT16260 is available in a 56-pin Shrink Small Outline
Package (SSOP) and 56-pin Thin Shrink Small Outline Package
(TSSOP).
