This 12-bit to 24-bit multiplexed D-type latch is
designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH16260 is 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
address
and
data
information
in
microprocessor or bus-interface applications. This
device
also
is
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.
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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16260 is characterized for operation from -40
°C to 85°C.
