DESCRIPTION/ORDERING INFORMATION
This 12-bit to 24-bit registered bus exchanger is
designed for 1.65-V to 3.6-V V
CC
operation.
The SN74ALVCH16269 is used in applications in
which two separate ports must be multiplexed onto,
or demultiplexed from, a single port. The device is
particularly
suitable
as
synchronous
DRAMs
microprocessors.

an

high-speed
Data is stored in the internal B-port registers on the
low-to-high transition of the clock (CLK) input when
the appropriate clock-enable (CLKENA) inputs are
low. Proper control of these inputs allows two
sequential 12-bit words to be presented as a 24-bit
word on the B port. For data transfer in the B-to-A
direction, a single storage register is provided. The
select (SEL) line selects 1B or 2B data for the A
outputs. The register on the A output permits the
fastest possible data transfer, extending the period
during which the data is valid on the bus. The control
terminals are registered so that all transactions are
synchronous with CLK. Data flow is controlled by the
active-low output enables (OEA, OEB1, OEB2).
